BHP Billiton Acts to Protect Floodplains
- BHP Billiton recently announced new initiatives for the Caroona coal project to ensure protection of the prime agricultural land on the floodplain and deep alluvial irrigation aquifers in the Liverpool Plains from long wall and open cut mining. "BHP Billiton and the NSW Government are committed to ensuring the protection of key agricultural land and the region’s water supply, through an amendment to the existing Exploration Licence 6505 that governs the Caroona Coal Project," said Jimmy Wilson, president-energy coal, BHP Billiton. BHP Billiton undertook a review of its exploration and development plans and has provided recommendations to help address community concerns …. read

Signal Peak Begins Production in the U.S
- Developers of a reactivated mine in southcentral Montana started shipping coal during early September to Midwestern power plants along a new 35-mile rail line, according to the Associated Press. The Signal Peak mine south of Roundup has undergone a $400-million expansion over the past year under the ownership of two Ohio companies, Boich Group and FirstEnergy. On September 3, 2009, Montana Governor Brian Schweitzer joined mining executives and Burlington Northern Sante Fe Railroad Chief Executive Matt Rose to dedicate a rail station that.…... read more

Feast, Famine and Faith
The Nordic region’s mining firms and technology suppliers have not escaped the chill winds that swept through the world’s financial and trading centers. But neither have they stopped key investment programs.
For some companies, particularly those producing zinc, 2008 was generally negative. But for most it was a year of two moods. Up until September, things seemed to be going very well, as was still the view of most mining and technology attendees at MINExpo in Las Vegas late in that month. A month later, when the first Euro Mine Expo took place in Skellefteå, Sweden, exploration drilling in the Nordic countries had pretty much been stopped, demand for industrial metals was disappearing, equipment orders were being postponed or withdrawn and equity markets slumped……. read

Mining High Latitude, Low Grade Magnetite
Iron ore production in the Nordic region is set to increase substantially with old mines being redeveloped, new resources exploited and existing mines expanded.
North of the Arctic Circle, the Fenno- Scandian Shield rocks of the Nordic countries host substantial magnetite deposits and some hematite. Substantial exploitation of these resources in three main areas started in the early 20th century. Although production by LKAB in Sweden has continued, the mines in Finland and Norway ceased working in 1988 and 1996. But the rapid growth in demand for iron ore in the present decade has occasioned a reevaluation of the resources previously mined in these locations...... read

New Boliden Keeps New Aitik on Track
The Aitik 36 project is expected on stream next March. Smaller precious and base metal miners have experienced varying degrees of success.
The Aitik open-pit mine near Gällivare is the largest single supplier of copper concentrates to Boliden’s Rönnskär smelter at Skelleftehamn, a 400-km haul by rail. The Aitik 36 project is intended to keep this feed stream cost competitive. The project will extend the mine’s lifespan from 2016 to 2027 and will double the amount of ore mined from 18 to 36 million mt/y. Aitik 36 is by far the largest of the series of expansions Boliden has undertaken since the company started the mine in 1968. It will cut the production cost per ton of metal for the mine and will enable ore with lower grades than at present to be mined profitably. New Aitik is expected to achieve full capacity in 2014...... read

Drills Stopped, Now Turning
Just as mineral producers in the Nordic countries reacted rapidly to the "credit crunch" so did explorers—possibly even faster.
Anders Wangby, working with Västerbotten County in northern Sweden, reports that in the weeks following the financial crisis there were no new applications for exploration permits and many of the junior companies stopped their drilling programs. This had a severe impact on the contract drilling companies, resulting in one bankruptcy. The foreign-based exploration companies were particularly affected, whereas the Swedish mining and exploration companies did not cut their programs as dramatically, and some continued at normal levels with their drilling activities. In Finland, exploration activities did not slow down as much as in Sweden, mainly because GTK, the government geological survey, continued its...... read

Time to Master Chess
Economic forecasting may be fraught with difficulty but thinking several moves ahead has become a necessity for technology providers
Some of the world’s major suppliers of mining and mineral processing technology and equipment owe their existence to the Nordic region’s domestic mining sector. Not neglecting those roots has provided a useful base load of "domestic" business for several companies during the downturn, for example Atlas Copco, Metso, Outotec and Sandvik’s ongoing commitments at Aitik. Neighboring markets in the CIS have also been of some help. Likewise, working with the construction as well as the mining industry has been an advantage; for example, Grindex pumps draining four locks on the Trollhätte canal in southwest Sweden...... read

Paste Processing Potential
The size and capacity of paste thickeners grow to meet the demands of surface tailings disposal
By Steve Fiscor, Editor-in-Chief
Dewatering slurries to the consistency of paste is currently one of the more crucial aspects of mineral processing today. The benefits represent enormous potential not only within the ore processing circuit, but down stream as well. The workhorses behind this technology is the paste thickener. The increased underflow solids content that a paste thickener can achieve can create real benefits for several applications, including the counter current decantation (CCD) circuit, mine backfill, autoclave feed and surface tailings disposal impoundments...... read

Nevada Mine Plans to Convert Geothermal Heat to High Voltage
Gold producer Florida Canyon will use heat recovered from its abundant supply of geothermal hot water to generate electricity
By Russell A. Carter, Managing Editor
With most of the mining industry still reeling from the financial blows of the global recession, it wouldn’t be too surprising to see some of the industry’s enthusiasm for "green" initiatives fading away, eclipsed by concerns about market trends, access to capital and other fundamental factors of business survival. The situation isn’t quite that cut-and-dried, however, as mineral producers are finding that there are some financial nuggets to be mined in the green fields of environmental safety, cleaner fuels and energy conservation, to name just a few…...

Pump Update: Pushing Performance Parameters
New products offer solutions for almost any pumping problem, from high head conditions to real-time data collection and alarm monitoring for large, mine-wide pumping systems
When it comes to pit dewatering and overall mine water management, there’s no one-size-fits-all solution—every mine is different. But thanks to a steadily flowing pipeline of new pump products, along with a constant stream of refinements to existing models, there’s almost always a ready solution for any size dewatering problem. Over the past year or so ,leading pump manufacturers have introduced a number of new models offering higher performance for challenging pumping applications.....

Clamp-On Ultrasonic System Solves Slurry Flow Measurement Problem - For a Chilean copper producer located in the Antofagasta region of northern Chile, finding a flow measurement system to replace their existing setup was a matter of thinking outside the box. Although several key performance requirements suited the electromagnetic flow meters the mining company had been using for years— including high accuracy and reliable performance— a pressing need for a low-maintenance, easily installed system disqualified that technology, and the company had to look elsewhere for alternative solutions …. read
