Winning electrowinning--Barrick's Zaldivar refinery puts Optibar technology through its paces

摘要

More than 40,000 tonnes of copper have been refined in a year-long test run of Optibar Inc.'s new technology at Barrick Gold's Zaldivar copper plant in northern Chile. The new segmented intercell bars being used in the Compafiia Minera Zaldivar refinery have slashed energy costs, reduced short circuits during refining and allowed the production of heftier, purer sheets of copper - gains that all promise to boost the plant's margins.
