From Ore to Nuggets, With Peril

CISITU, Indonesia — In the remote mountains of West Java, workers like 15-year-old David Mario Chandra are an integral part of Indonesia’s gold industry.

A workshop next to his family’s house in Cisitu, in Banten Province, contains machinery that turns gold ore into usable nuggets. The procedure seems simple enough: The crushed ore is tumbled with other ingredients in cylinders called balls until the valuable stuff is amalgamated. But there is a crucial material — and a final step — that alarms environmental and health experts around the world.

Chile Debates Bill Making Mines Use Desalinated Seawater

Chilean lawmakers have presented a bill that would force mining companies including Anglo American Plc and BHP Billiton Plc to run all of their copper mines in Chile using desalinated water from the Pacific Ocean.

The lower chamber of deputies’ measure that was introduced last month would require mines using more than 150 liters (40 gallons) of water a second to incorporate seawater in their operations, according to a statement on the Congress website. A third of the world’s copper supply comes from Chilean mines.

BHP says U.S. shale business to generate cash by 2016

LONDON, Dec 10 (Reuters) – BHP Billiton, the world’s largest miner and a top investor in U.S. onshore oil and gas, said on Tuesday its U.S. shale business should generate cash from 2016, contributing almost $3 billion a year to the group by the end of the decade.

BHP, one of the largest producers outside the major integrated oil companies, plans to spend around $4 billion a year to expand its U.S. onshore oil and gas production.

Indonesia’s president to weigh into mineral export confusion

“The president will decide it,” Trade Minister Gita Wirjawan told reporters on Wednesday, noting that Yudhoyono would make an announcement after consultations with the chief economic minister, the energy and mineral resources minister, the trade minister, the industry minister and parliament.

Lawmakers last week told the government they would not dilute the law, adopted five years ago, and it must go ahead as scheduled. Officials have been pressing for a reprieve, at least for miners that can show they have been trying to meet demands to process their ore before it is loaded on ships for export.

Indonesian gov’t, Japanese consortium agree to terminate smelter contract

JAKARTA, Dec. 9 (Xinhua) — The Indonesian government and the Japanese consortium Nippon Asahan Aluminium (NAA) on Monday clinched a deal to terminate a contract that allows the latter to run PT Inalum (Indonesia Asahan Aluminium), thus paving the way for Indonesia to solely own the only aluminum smelter in the region.

Indonesia trying to skirt its own ban on mineral ore exports

Dec 9 (Reuters) – Indonesia’s government is still trying to find a way around a mineral ore export ban that the country’s parliament is refusing to allow it to sidestep, chief economic minister Hatta Rajasa said on Monday.

The ban, which comes into effect next month, is designed to increase the value of the country’s mineral exports. Indonesia has for decades and with limited success tried to create more value from its vast array of natural resources.

Raw Mineral Export Ban Looms

Small- and medium-sized domestic mineral miners voiced concerns on Friday that they lacked the funds to comply with a long-anticipated ban on unprocessed mineral exports, due to begin next year. The current regulation indirectly favors large international firms, they said.

“The national mining industry will die before it develops,” the Indonesian Mineral Entrepreneurs Association said in a statement on Friday.

The association, known as Apemindo, argued that local miners, most with operations less than 10 years old, did not have enough capital to build their own smelters. Apemindo said that the ban would benefit foreign mining companies that had been operating in the country for many years and had already accumulated sufficient profits to build their own smelters.

Chinese steel mills need huge upgrades – General Electric

General Electric sees “tremendous upgrade opportunities” in China’s steel industry, the world’s largest, as more mills are revamping their facility to become more efficient and environmentally friendly.

The US giant expects Chinese mills, facing tighter environmental rules as they become global players, to require energy-efficient technologies and solutions on a big scale, although GE is unable to quantify the market size now, said Joe Mastrangelo, CEO of GE’s power conversion business.
