Baden, Switzerland, August 29, 2011 – ABB, leading power and automation technology group, was recently contracted to supply the drive system for a new semi-autogenous grinding (SAG) mill at Neves Corvo, Portugal. The contract was awarded in June 2011. Neves Corvo is an underground mine, located 100 km north of Faro Portable Cone Crushing Plant within the Iberian Pyrite belt and one of Europe’s most important copper mines. It started operating in 1988, producing both copper and zinc-ore. The company changed ownership in 2004 and is now fully owned by Lundin Mining. ABB’s scope of supply includes two converter transformers, one excitation transformer, an MV frequency converter and one synchronous motor. The MV frequency converter operated motor will improve the grinding process by varying equipment speed as needed. Its low speed operation will allow for removal of the gearbox from the drive train, thus reducing costs and need for maintenance as well as increasing efficiency. It will also improve operation by enabling frozen charge protection, controlled roll back, as well as inching and creeping for service purposes. This new mill will be operated with the world largest single Portable crushing plant pinion low speed drive system. The available shaft power is 8500kW with a motor speed of 174rpm. ABB‘s good relationship with Lundin Mining, existing project references and state-of-the-art low speed grinding solutions helped to win this order. This solution offers the highest power for a mill application of its type and has been proven at various installations around the globe. The ABB supply will optimize Neves Corvo’s process, increase production efficiency and improve its energy efficiency. Equipment delivery is scheduled for the third quarter of 2012, with installation and commissioning scheduled for early 2013. Lundin Mining Corporation has operations in Ireland, Sweden, Spain and Portugal where it specializes in base metals mining, producing copper, zinc, lead and nickel. The company is currently expanding its Neves Corvo mine and equity stake in the Congo worldclass copper/cobalt mine Tenke Fungurume.

In addition to its importance for human civilization as an industrial metal copper also plays a vital role in the immune system as a killer of foreign microbes. S.E. Gould writing for Scientific American provides an Jaw crusher for sale interesting breakdown of the red metal's ability to destroy microbes and its use by the human immune system to dispatch bacterial threats. Despite its innocuous reputation and commonplace nature copper is a toxic substance in quantities of more than an atom per cell, which accounts for its tremendous bacteria-killing capability. According to Gould, although large amounts of copper are toxic for almost all living cells, it is this very toxicity which make the metal a vital ingredient for complex organisms such as human beings, who exploit its lethal propensity as a tool for their immune systems. The white blood cells of the human immune system Stone Crusher Plant Sale surround invading bacteria upon activation before boosting their levels of copper ions in order to break down the threatening intruders. This is the reason that insufficient copper levels weaken the human immune system as well as increase susceptibility to sickness and infection. Gould also notes that many pathogenic bacteria have developed copper-resistant genes, which when confronted with heightened copper levels are capable of manufacturing proteins to expel the deleterious ions.

Qatar's sovereign investment fund, the second largest shareholder in Xstrata PLC (LON:XTA) with 12% of equity, confirmed Monday it is looking positively at the company's planned merger with Glencore International (LON:GLEN). Speaking to reporters in the capital Doha, the country's Hydraulic cone crusher prime minister, Sheikh Hamad bin Jassim al-Thani, said Qatar Holdings is “looking in favour of doing something between the two companies.” The news come as a relief for the parties involved in the intended merger, one of the mining industry's biggest ever deals, as Qatar Holdings had earlier thwarted what was expected to be an untroubled merger of the two Swiss-headquartered commodities firms. The group intended to obtain a more generous cone crusher for sale appraisal of Xstrata shares, which in the revised deal are valued at 3.05 Glencore shares from a ratio of 2.8:1 previously. The transaction, five years in the making, would lead to the creation of a new force in the global mining industry comparable in clout and stature to diversified mining giants Rio Tinto (LON:RIO) and BHP Billiton

Petaquilla Minerals Ltd. (TSX:PTQ) has rejected as inadequate an unsolicited, a $112-million takeover bid for the company by Inmet Mining Corp. (TSX:IMN), which operates a gold mine adjacent to Petaquilla’s ball mill for sale Molejon project in Panama. The Canadian gold producer said in a statement that its board of directors unanimously rejected Inmet’s offer because they thought it undervalued the company and its potential growth prospects. “The Inmet offer does not adequately reflect Petaquilla’s current value or the value of Petaquilla’s substantial growth prospects, nor does it take into account the true value of Petaquilla to Inmet and its shareholders,” CEO Richard Fifer said in the statement. Inmet was offering 48￠ a share in cash or 0.109 Inmet shares for each Petaquilla share, which works out to a 37% premium over the stock’s closing price prior to the launch of the bid in early September. Last month, the Department of Mineral Resources of Panama impact crusher for sale rejected a petition filed by Minera Panama, S.A., a subsidiary of Inmet Mining Corporation, in respect to the belt known as the San Juan concession. The area is comprised of 11,145 hectares, which Petaquilla Minerals has the rights to explore as granted by the Department of Mineral Resources in 2007. Inmet received in August a whopping $1 billion from fellow Canadian Franco-Nevada (TSX & NYSE: FNV) to support the development costs of Inmet's massive Cobre Panama copper project, the country's largest-ever mine development. In exchange Franco-Nevada will get a future steam of precious metals. Petaquilla's Molejon project neighbours Inmet's $6.2 billion Cobre Panama copper-gold porphyry project, the first large-scale mine in the Latin American country’s history. Cobre contains more than 32 billion pounds of copper, according to Inmet’s estimations, almost nine million ounces of gold and 168 million ounces of silver in measured and indicated resources. The mine is expected to ship its first consignment of concentrate during the first quarter of 2016, and the life-of-mine is expected to exceed 31 years. Image: The Panama Canal

Turquoise Hill Resources (NYSE:TRQ TSE:TRQ) fell 6% in afternoon trade on Monday after the company said it received a letter from Mongolia's mines minister asking to renegotiate a deal signed in October 2009 that gave the country 34% ownership of the massive Oyu Tolgoi mine.

Rio is in the process of putting together a finance package of an additional $3.5 billion – $4 billion on top of the $6 billion already spent to take Oyu Tolgoi to full production status, butVertical shaft impact crusher a research report leaked earlier this year indicated final overall costs could come in at as much as $13 billion. The mine is set to produce more than 1.2 billion pounds of copper, 650,000 ounces of gold and 3 million ounces of silver each year.
