Gold geothermal energy underground carbon storage and more up for debate at

first_imgThe revival of Victoria’s gold sector, coupled with emerging opportunities in other base metals, mineral sands, geothermal energy, and some of Australia’s most likely locations for underground carbon storage, will all be on the agenda at the 2009 Paydirt Resources Victoria Conference. Since 2008, Victoria’s minerals industry has been bolstered by a variety of legislative and incentive-driven advances – most notably the passage in February of the 2009 Resource Industries Legislation Amendment Act, which from next year will begin to reduce regulatory burdens on mining and exploration ventures across the State. Victoria’s Department of Primary Industries has gone on the front foot in attracting greater mineral exploration through its ‘Rediscover Victoria’ initiative, which has committed an initial A$5 million to support drilling programs and other exploration work in new or previously unexplored parts of the State.At Melbourne’s Hilton on the Park from August 17 – 19, the Paydirt Conference – which follows on from a highly successful inaugural event at the same location last year – will be officially opened by Victoria’s Minister for Energy and Resources, the Honourable Peter Batchelor, shortly after 9 AM on Monday August 17.More than 300 delegates are expected to attend over the three-day conference, including a broad variety of mining and exploration executives, bankers and brokers, industry analysts, engineers, geologists, mining services and equipment suppliers, and heritage and community relations specialists.Despite the recent scaling back of Lihir Gold’s Ballarat mine, gold production continues to flourish at Victoria’s two largest operating gold mines in Stawell and Fosterville near Bendigo – and the State Government is confidently predicting that production this year will easily outstrip the 6 t of gold produced in Victoria in 2008.High on the agenda at next week’s Conference will be the key role that Victoria has to play in the growing demand for geosequestration, or deep underground storage, of greenhouse gases, which has developed into an important plank of the Australian Government’s long-term carbon reduction strategy.Among the key speakers will be Peter Cook, CEO of the Cooperative Research Centre for Greenhouse Gas Technologies (CO2CRC), one of the world’s leading carbon capture and storage (CCS) research organisations, which only last week was boosted by a A$20 million grant from the Federal Government’s Cooperative Research Centres Program.CO2CRC now has three CCS demonstration projects in operation, including the widely watched Otway project in southwest Victoria, where carbon dioxide has been successfully injected and stored 2 km underground. Also presenting at the Paydirt Conference will be Charlie Speirs, Director of the newly formed State Government body, Clean Coal Victoria, which has been handed the complex challenge of engineering lower-emissions uses for Latrobe Valley’s huge brown coal reserves – source of 90% of Victoria’s power generation.Major industry bodies that will provide presentations during the first two days of the Conference include GeoScience Victoria, the Australian Geothermal Energy Association, and the Australian Petroleum Production and Exploration Association.On the third day of the Conference – August 19 – a technical forum offers delegates the opportunity to access the latest world class geoscientific data and information from GeoScience Victoria, including new seismic data from its ‘Gold Undercover’ project and new regional 3D models from the Rediscover Victoria initiative.last_img read more

Volvo L250G wheel loader provides flexibility in limestone operation

first_imgVolvo Construction Equipment (Volvo CE) chose a German wheel loader customer to demonstrate the new L250G wheel loader – which is transforming the way the company does business. The L250G has revolutionised efficiency for LBT. It provides a perfectly sized machine for loading semitrailer trucks in rehandling applications and rigid haulers at the rock face. The L250G effortlessly tackles a variety of tasks. And rather than making four cycle loads, the L250G can finish the job in only three because of its larger bucket. This is saving time and money – as well as fuel.Löderburger Baustoff + Transport (LBT) operates a quarry in the small town of Stassfurt in Germany. Part of the larger Ferdinand Wesling Group, LBT owns a number of rock and sand quarries scattered across northern Germany, as well as other holdings like logistics companies, concrete plants – and even a museum called Dino Park, a showcase for a dinosaur footprint discovered in a quarry in Münchehagen. The Wesling Group is a major Volvo CE customer, running a fleet of 35 wheel loaders across Germany – 10 of which are at work in the Stassfurt quarry – and purchasing two or three new machines each year.The business has been in Ferdinand Wesling’s family since his grandfather, also named Ferdinand, founded it in 1925. After the present Ferdinand took over the company, he saw an opportunity for expansion into then-newly opened East Germany, and in 1991, he acquired the Stassfurt quarry, which now yields more than 2 Mt/y of limestone. The stone is used for shaft furnace bricks for the local sodium carbonate producer, chippings for concrete and asphalt mixtures for road construction, building blocks and other road construction materials. The 50-ha mine, now 55 m deep, is so busy feeding the sodium carbonate factory that LBT employees work seven days a week, 365 days a year, with Volvo loaders putting in 10- to 16-hour days. Which is one major reason why Ferdinand uses Volvo machines: he counts on receiving specialised service as soon as he needs it. At the dealership in nearby Magdeburg, two service technicians have specific knowledge of each machine in LBT’s fleet. The dealer’s flexibility and Saturday service are important for a company that can’t afford any downtime.In 2008, LBT switched its entire fleet of excavators over to Volvo wheel loaders. “They’re just flexible for our needs,” says Ferdinand. “They’re easier for us to work with and more versatile, and we’ve found that – for our purposes in this quarry, at least – we can achieve better fuel efficiency with wheel loaders doing the work.”With the newest acquisition, LBT found that it can achieve even better fuel efficiency. Because of its history with Volvo CE, LBT was chosen to test out the new Volvo L250G wheel loader. It’s not unusual for the Wesling Group to be on the cutting edge of new machinery and technology: it was also one of the first customers in Germany to acquire the new L350F wheel loader after it came out in 2008.The demo machine will soon leave the Wesling Group’s hands and move on to job sites in southern Germany and Austria; other L250G demonstration units will also go to work in Sweden and the Netherlands. But as its first user, Ferdinand is impressed. “Once we can specify an L250G to meet our exact needs, it will be the perfect machine for us.”last_img read more

At present, there are seven 10-Mt coal mines and three 20-Mt coal mines in the coalfield.Also last year, in October, the Zhunneng Heidaigou opencast coal mine, which is the largest opencast coal mine in China with a design annual output of 20 Mt/y, achieved safe production of 2,000 days with “zero death and type-B & non-casualty incidents,” the company reported. During this period, the mine produced a raw coal output of 139 Mt and a total exploitation volume of 601 million m3, “setting two new records in the annual exploitation volume and raw coal output efficiency in opencast coal mines of China.last_img read more

Tenova TAKRAF supplies reverse pulse bagfilters to PPC

first_imgTenova TAKRAF Africa has been awarded two contracts by South Africa’s leading cement producer, Pretoria Portland Cement (PPC), to supply reverse pulse bagfilters to replace existing  electrostatic precipitators (ESPs) at PPC’s slurry facility near Mahikeng, North West Province, and its De Hoek cement plant in the Western Cape.  Tenova TAKRAF Africa is part of the global Tenova Mining & Minerals Group.Replacement of the ESPs with reverse pulse bagfilter technology is part of  a PPC company-wide initiative to upgrade its dust control systems.  This initiative is in line with the company’s ongoing commitment to ensuring a safe and clean work environment, meeting increasingly more stringent requirements of South Africa’s National Environmental Management: Air Quality Act.Tenova TAKRAF‘s scope of work on both contracts covers design, supply, delivery, installation, commissioning and performance testing of the bagfilters, as well as  stripping of existing ESPs.  The contract for PPC Slurry was awarded in July 2013, and for PPC De Hoek in September 2013. Both are due for completion at the end of May 2014.The reverse pulse bagfilter for PPC Slurry is being installed on two finishing mills, handling an inlet dust load of 400 g/Am3, at a flow rate of 30,000 Am3/h. The guaranteed emission rate is less than 20 mg/Nm3. The two reverse pulse bagfilters at PPC De Hoek are being installed on the kiln and raw mill, handling an inlet dust load of 75 g/Am3, at a flow rate of 300,000 Am3/h. The guaranteed emission rate is also less than 20 mg/Nm3. Tenova TAKRAF Africa had previously supplied a bagfilter for installation on the plant’s mill some three years ago.Tenova TAKRAF Africa has an extensive business relationship with PPC, with a reference list covering the supply of cement plants through to belt conveyor and dust control systems.  Its reverse pulse bagfilter technology has found wide acceptance, with some 2,000 installations in place in southern Africa in a vast variety of applications and in many different industries. The bagfilters handle flow rates from 0.5 to 100 m3/s and enable economical collection of dust at high filter rates with collection efficiencies >99.99 %. These high efficiencies are maintained under variable operating conditions by reverse pulse action, with the bagfilter being able to operate 24 h/day under arduous conditions. Filterbag inspection is easy and replacement of the bags is done from the clean-air side, minimising any risk to the maintenance staff.last_img read more

Whats best and who in surface mining

first_imgWe will be closing the nominations for the International Mining Technology Hall of Fame in August. Do you wish to nominate someone who has contributed in an outstanding way to technology development in surface mining or efficiency, safety, productivity, etc.in that discipline? Contact john@im-mining.com about nominations.The chosen nominees will be inducted at the International Mining Technology Hall of Fame gala dinner at the Hyatt Regency at Colorado Convention Center, Denver on February 25, 2019. The dinner is a key event in the SME Annual Conference week.The current nominations shortlist in the Surface Mining has MineWare founder and CEO Andrew Jessett, who has been actively involved in the advancement of Australia’s dragline and shovel monitoring systems over the last decade including the pioneering Universal Dig and Dump (UDD) dragline technology. Andrew founded MineWare after creating and commercialising the world’s most advanced dragline monitoring system, Pegasys.Pekka Heikkonen (pictured on the right) is the man behind the development of the Rammer Hammer and that great hydraulic breaker line that is now part of the Sandvik Mining offering.Aleksandr Egorov, General Design Engineer, Belaz headed the engineering team that made the first attempt to create an ultrahigh payload capacity dump truck (more than 400 tonnes) back in 1997-1998. This eventually led to the development of the BELAZ-75710 haul truck. The truck has two entries in the Guinness World Records book.The last on the shortlist is Dr Shahram Tafazoli (current CEO of Motion Metrics International Corp) who led a team of just three engineers with the goal of solving some of the mining industry’s most challenging problems. In 2003, a big break came when an oil sands mine in Alberta asked for a solution to a serious problem they were having: the bucket teeth on their shovels were unknowingly breaking off and ending up in the crusher, which would end up blocking the crusher for hours, costing them hundreds of thousands of dollars for each occurrence, and creating a very dangerous situation for the mine. Tafazoli solved this problem.The last inductee was Kenneth F. Lane who led the way for value based optimisation of the full scope of mining activities; in particular, showing how cutoff grade policies bridge the disciplines and he developed the framework for maximising the whole project value by optimising this policy every year as the resource was depleted. This work led to more valuable mining in many of the largest surface mines in the world and for the underground projects that have used these principles. http://www.im-halloffame.com/surface-mining/There is a total of 12 categories and nominations are welcomed for all of them: Bulk Handling, Concentration, Comminution, Exploration, Environmental Management and Stewardship, Metallurgy, Mining Software, Safety, Surface Mining, Underground Development, Underground Production and Outstanding Innovator.www.im-halloffame.comlast_img read more
