Iron ore processing experts announce collaboration on major beneficiation projects

first_imgCDE Global and ProMet Engineers have announced the signing of an agreement which will enhance the options available to iron ore processors requiring beneficiation systems in order to maximise efficiencies from their operations. The agreement will focus on the development of a new suite of iron ore beneficiation plants aimed at small and medium sized processors for whom the current plant offering does not cater.“We are focusing on the development of range of iron ore beneficiation plants for operators requiring capacities up to 2.4 million tons per year” explains CDE Asia Managing Director, Manish Bhartia. “Up until now this is a segment of the market that has been overlooked by existing suppliers to the industry. The agreement we have signed with ProMet Engineers will allow for both companies to bring together their individual expertise to create new, innovative processing systems for the iron ore industry.”CDE identified this gap in the market following the experience they have gained in recent years in the design and delivery of turnkey iron ore washing plants to steel producers in India. “The expansion of our offering to include full beneficiation is the next logical step as we seek to expand our market coverage in India” explains Bhartia. “As we examined how we can best achieve this it became clear to us that ProMet Engineers were the perfect match.”For many small to medium sized steel producers there are significant benefits to be enjoyed from the introduction of a full beneficiation plant but the level of investment currently required in order to get a system like this fully operational is a significant barrier. “Our iron ore washing plants are delivering significant efficiency improvements for operators thanks to the reduction in silica and alumina levels and the subsequent increase in Fe content they are delivering” says Bhartia. “The development of this new suite of beneficiation plants will give smaller operators the opportunity to further improve efficiencies within their processing operations and enhance their capability to grow.”ProMet Engineers mirror the enthusiasm from CDE for the new collaboration as they seek to develop coverage in India. The company has developed significant experience working in the Australian and African markets through its offices in Perth and Cape Town and in recent times has been concentrating considerable efforts on building a project portfolio in the Indian market. “We can count some of the largest iron ore processing companies in the world among our customers” explains Chairman of ProMet Engineers, Jim Cribbes. “Given this experience and the levels of iron ore available in India it is a market that is of significant interest to us. The new agreement with CDE will allow us to marry our process engineering expertise in iron ore processing with CDE’s capability in the delivery of turnkey mineral processing projects.”In addition to the processing of iron ore, ProMet Engineers also has significant experience with a range of industrial minerals and have also worked on many coal and non ferrous processing systems including gold, nickel, silver, zinc and lead among others. “This agreement with Promet in India is the first stage of a process that will allow both companies to take advantage of the opportunities that exist for our systems on an international level”  says Chairman of CDE Global, Tony Convery. This is echoed by ProMet Engineers Managing Director, David Glynn who says “The ProMet Engineers CDE partnership moves us both closer to our long term strategic objectives. The significance of this development not only for both of our companies but in terms of the enhanced product offer it creates for mineral processing companies in India cannot be over emphasised.”last_img read more

German mining technology aims to make Colombian mines safer

first_imgGerman technology and German knowhow are to help the Colombian coalmining sector, underground mining in particular, to become safer and increase its production. A strategic co-operation is planned that is to comprise not only a safety partnership but also technology transfer. Juan Gabriel Ceballos Campuzano is the owner of Colombia’s old-established family mining firm Soc Central de Activos Mineros, based in the Colombian capital of Bogotá. Aiding the development of heavy industry in the country on behalf of the government Ceballos’ grandfather laid the foundation stone for the firm over half a century ago. Today about 350 people are employed at Ceballos’ mine. Last year he produced 150,000 t of high-grade coking coal and the figure is set to rise considerably in the near future. In about four years, he says, “we want to increase production tenfold to 1.5 Mt”. The Colombian wants to generate the necessary capital for this – a not inconsiderable EUR10 million – on the US stock exchange. He wishes to buy new machines – for which an initial sum of some EUR7 million has been budgeted – primarily from Germany. Although the machinery does cost “about 50% more there” seen in the medium and long term this is still a “good move”.Ceballos was part of a 27-man delegation of Colombian mine operators and mining experts recently visiting Germany on a week’s tour of the Saarland, a region with a long mining tradition. The program included visits to suppliers, an underground colliery tour and a seminar on mining safety. In 2010 alone official statistics list the number of deaths resulting from mining accidents in the Andean nation as 173. In the last three years the figure was over 400 while the number of unreported cases is likely to be considerably higher. Some 80,000 people in total are employed in coal mining and about 35,000 of these in open-pit mining.Commenting on standards Manfred Schmidt from the German Engineering Federation (Verband Deutscher Maschinen- und Anlagenbau – VDMA) in charge of visit co-ordination said a large proportion of underground coal mining in Colombia is “at the stage of coal mining in Germany 50 to 100 years ago”. Schmidt is planning a project supported amongst others by the German-Colombian Chamber of Commerce which is aimed at remedying as quickly as possible the still frequent serious shortcomings prevalent in the mining sector especially underground. The aim here is to build up a strategic co-operation that will include both a safety partnership as well as technology and knowledge transfer. Ceballos says the Colombians are particularly interested in special solutions due to the often difficult extraction conditions faced there.Of the 79 Mt of coal produced by the South American country last year some 70 Mt were extracted at open-pit mines. The remaining 9 Mt were mined underground by about 4,000 mainly small or micro mining operations. With a few exceptions these operators scarcely attain annual production of more than 10,000 t each. Furthermore, half of them are operating illegally. These mines have neither mining authorisations nor any other necessary permits and documents. “Only about 5% of these mines” says Ceballos, “are properly equipped”. His country, he said, could learn a lot from the Germans, adding that the nation is now in the process of restructuring mining controls. Major changes are already pending over the coming months, he said. The new rules are to be far stricter than those of the past. Ceballos is convinced “the sector will continue to consolidate.” Small operations will have to merge with larger ones to deal with the stricter regulations in financial terms. Here, too, help from abroad is welcome. This, he said, would not only improve mining safety but also environmental protection. There is still “a lot to do” in both these fields.Colombia boasts one of the best grades of coking coal in the world. At present some 5 Mt are produced annually, largely for export. This makes the country the world’s fourth largest exporter of coking coal. Existing resources are estimated at some 2,000 Mt. Ceballos says over the next ten to 15 years they want to increase exports to an annual 20 to 30 Mt. This is double the amount currently produced in Germany. Costs for this stand in the high double-digit millions. Ceballos says: “To produce a million more tons of coking coal we need additional investment of $ 3-4 million.” If the cooperation with Germany runs to plan not an inconsiderable proportion of this money will flow into the coffers of German mining suppliers.last_img read more

National Mining Association NMA welcomes new member Hitachi Consulting

first_imgNMA recently welcomed new member Hitachi Consulting, the global management consulting and IT services business of Hitachi Ltd, a global technology leader and a catalyst of sustainable societal change. In that same spirit—and building on its technology heritage—Hitachi Consulting is a catalyst of positive business change by delivering measurable, sustainable business results and a better consulting experience. Recently, Hitachi Consulting helped Shell Albian Sands increase truck availability to 83% and sustain it at that level, improving the mine’s production potential. Hitachi Consulting says it “has more than 25 years in the metals and mining sector spanning over 100 successful projects worldwide delivering over $700 million in operational value. Our mission is to preserve mining portfolio value by optimising and sustaining the performance of physical, human, systems and data assess across mining operations. We deploy technology enabled management consulting services from mines to mills to markets.” As a Hitachi Ltd company, it can partner with clients across all of mining capital, environmental and safety requirements to fulfil its “social innovation vision of contributing to society through the development of superior, original technology and products.”An example of its work is the Mobile Maintenance Excellence Initiative (MMEI) Shell Albian Sands launched in partnership with Celerant Consulting (now Hitachi Consulting), Caterpillar and Finning. The goal of the program was an ambitious double-digit increase in truck availability.High truck availability is a key to achieving production at or near Shell Albian’s Muskeg River mine’s design capacity of 155,000 barrels of bitumen per day.Shell Albian Sands invited Caterpillar and Finning to participate in MMEI. Finning supplies Shell Albian Sands with heavy equipment as well as mechanics to perform on site maintenance and repair. About 200 Finning employees work at the Muskeg River mine alongside the roughly 1,300 employed there by Shell Albian Sands.MMEI team members from Shell Albian Sands, Finning and Caterpillar gathered weekly with Celerant to shape the improvement initiative; clearly define and document the improved processes and the respective roles and responsibilities for Finning and Shell Albian Sands personnel; review project progress and assign new action items to remove barriers and move MMEI forward. Once the maintenance process was redesigned, Celerant worked with the MMEI team to customise the management control and reporting system (MCRS®). Today the MCRS drives timely, coordinated decision making and ensures that people at each level of authority have ready access to critical data as well as the power to influence the results for which they are accountable.Truck availability increased to 83% and sustained at that level, improving the mine’s production potential. Also, operating costs were trimmed more than C$30 million. Mean time between truck stoppages increased from 42 to 72 hours. Preventive maintenance completion rate improved from 52% to 100%.last_img read more

Sonic Drillings Ray Roussy joins the International Mining Technology Hall of Fame

first_imgDeveloper of the sonic drill, Canadian Ray Roussy will be inducted in the Exploration category at the gala dinner in the Brown Palace Hotel, Denver on February 16 ( Roussy, President of Sonic Drilling Ltd and the Sonic Drill Corp is the patent holder and the developer of modern day sonic drilling technology – a technology that has made a significant impact on the mining industry. Today, seven out of 10 sonic rigs are purchased for mining exploration. Although the diamond drill has long been the preferred tool for mineral exploration in hard rock, in unconsolidated material, it has two unfortunate drawbacks. First, it doesn’t drill well in unconsolidated materials and, secondly, it can’t provide accurate core samples from that kind of formation. Only a sonic drill can recover a continuous core including boulders, clays, silt, sand and gravel and lay it in its stratigraphic sequence – from the surface all the way down to 100 m and deeper.Using Roussy’s innovative sonic drill head, samples, ranging from 3” to 8” in diameter, can be obtained from a wide variety of mineral deposits including hard-to-extract oil sands, slag piles, mine tailings and heap leach pads. Extruded into clear plastic sleeves and then neatly laid out, these core samples can be subjected to a detailed visual examination and analysis, followed by sampling, photographing and archiving for a permanent record of the existing mineral conditions and a comprehensive evaluation.Building his first sonic drill rig in his backyard more than 30 years ago, Roussy’s lifetime work has resulted in three prestigious awards, thanks to the unique features of his sonic drilling technology. The Roussy sonic drill head can:Drill three to five times faster (some users report ten times faster)Produce 70% less mess on siteDrill without the use of drilling mudDrill through mixed soils with easeProduce continuous core samples to 100 m+Use 50% less powerOffer many environmentally-friendly benefits including less noise, less waste, lighter engines, reduced fuel consumption, a smaller footprint and “green” hydraulic oil.Roussy’s sonic drill has overcome all of the traditional hurdles to cost-effective mineral exploration in unconsolidated material, making him a worthy member of the International Mining Technology Hall of Fame.The Sonic drilling technology has recently been nominated for a fourth award. The Northern Ontario Institute of Technology (NOIT) has nominated Roussy for an Ontario Premier’s award.Roussy is an alumni of NOIT where he was first introduced to mechanical engineering before continuing onto Lakehead University where he graduated with a Bachelor of Mechanical Engineering degree in 1974.Today, 40 years later, Roussy holds dozens of patents involving sonic drilling technology and is solely responsible for the successful commercialisation of it when others failed to make it work. If Roussy wins the Ontario Premier’s award, it will be the fourth award since 2008 for his technology.Today, award-winning sonic drill rigs, patented and built by the Sonic Drill Corp, are in use on six continents and in every application imaginable. Due to its non-intrusive abilities, sonic drilling technology has often been used (and specifically requested in government contracts) for sensitive projects such as dam remediation, nuclear site investigations and hazardous waste site reclamation.Because vibrations from the drill bit are not transmitted very far beyond the drill, penetrations can occur into very sensitive areas such as critical eco-systems, unstable terrain or vulnerable situations where traditional drilling would cause more harm or be impossible to complete.Initially, sonic drilling technology was seen as a powerful environmental investigation drill due to its ability to provide undisturbed core samples but, now, the technology has broadened in use to excel at geothermal installations, piling and mineral exploration.last_img read more

Leach thickener upgrade by FLSmidth boosts performance at gold mine

first_imgFollowing test work, a process review and structural analysis of the bridge and thickener tank, the FLSmidth team recommended a combination of the E-DUCÒ feed dilution technology and the E-Volute™ feedwell. The E-DUCÒ system uses feed stream momentum to induce large volumes of feed dilution prior to the feedwell, thus optimising flocculation due to improved mixing profiles and residence times.“The E-Volute feedwell is characterised by excellent feed stream energy dissipation, optimal mixing energy and shear profiles. Subsequently, it promotes even feed distribution into the thickener with minimal floccule breakage, therefore improving the overall sedimentation performance. Specialists at the FLSmidth Supercentre in Perth completed the project from on-site test work and inspection, to process and mechanical design, fabrication of all components, installation, and finally, commissioning. No other OEM has the ability to provide such a breadth and depth of service.”“Having control of the project meant we could keep to the required tight delivery schedule, while remaining in control of quality and planning on-site. This ability helped to shave three full shifts off the installation, allowing the site to return to full production far earlier than they had thought possible,” says Smith.Initial data analysis shows a reduction in flocculant dose of approximately 34% and an increase in underflow density by approximately 2 wt% during the first two months. As the plant continues to optimise the new system under FLSmidth’s recommended control setup, flocculent savings are maintained and underflow densities have increased up to 8 percentage points from 48 wt% to 56 wt% (6% on average), limited only by the rake drive torque.In addition to the achieved flocculent savings, the increase in leach feed density reduced total volumes reporting to the CIL, the minerals recovery process, by around 16.5%. Decreasing cyanide and lime requirements while significantly increasing available leach residence time, promoting gold recovery. The results are such that the 34 m leach feed thickener with FLSmidth technology is producing higher densities than the 44 m tailings thickener with non-FLSmidth OEM technology. Reduced flocculant consumption and improved operational performance are the results of a thickener upgrade at a large Australian gold mine. A leach feed thickener was creating a bottleneck in a gold mine in Western Australia. The installed thickener was a preinstalled ‘off-the-shelf’ product, neither supplied nor installed by FLSmidth. As the on-site maintenance contractor, the client asked FLSmidth’s team of specialists to assess the performance and offer a solution to improve productivity and overall performance. As a result, FLSmidth’s engineers identified several improvements to the thickener’s control set-up.“The customer realised their feed system was under-sized and hampered by air entrainment. The density-reliant dilution system meant that the feed stream was not being diluted, resulting in high flocculant consumption, poor overflow quality and lower than desired underflow density,” explains Dane Smith, Dewatering Product Manager at FLSmidth.last_img read more

Sandvik mining order intake up 15 year on year and operating profit

first_imgIn divestments, the Mining Systems conveyor components business, including the closely related specialist conveyor systems business in Hollola (Finland), was divested to NEPEAN. Mining Systems has been reported in discontinued operations and the divested businesses has as of 2 November 2017 been deconsolidated from Sandvik’s financial statements. The projects to be finalised during 2018–2019 by Sandvik, through an operational agreement with FLSmidth, will however remain reported in discontinued operations.Sandvik is also evaluating the strategic options for Sandvik Drilling and Completions (Varel). The business being reviewed relates to the oil and gas industry, representing about 70% of the total revenues of approximately 2 billion SEK generated in 2017 by Sandvik Drilling and Completions. The remaining approximately 30% which manufactures and services application specific roller cone bits primarily to the mining industry, is not included in the review and continues to be core operations of Sandvik Mining and Rock Technology. In its just released Q2 2018 report, Sandvik reports that business is booming – its Mining and Rock Technology business saw order intake improve organically by 15% year-on-year on strong development in most product areas. Revenues increased organically by 16% supported by strong order intake in recent quarters and favorable demand in the aftermarket business.Key items impacting order intake and revenues compared with the year-earlier period:• Order intake was driven by high demand for replacement mining equipment as well as expansion of activities inalready existing mines and high customer activity in the aftermarket business.• Strong growth for both underground and surface mining equipment.• In the equipment business, drilling, crushing and screening accounted for the strongest growth in relative terms.• Growth in the aftermarket business improved significantly, with strong development for both parts & service andconsumables.• All geographies noted a strong underlying activity level. The greatest increase in order intake in relative terms wasnoted in North America, while the timing of orders implied a negative development for Australia.• The aftermarket business accounted for 60% of revenues while the equipment business accounted for 40%.Operating profit improved by 24% and the operating margin increased to 17.1% (16.0), including an adverse impact from changed exchanged rates. Items impacting operating profit and operating margin:• Positive organic growth in revenues of 16% improved the absorption of fixed costs in production.last_img read more
