The company runs resource exploration, mining, mineral smelting, and further processing of copper ore concentrates and other nonferrous metal ores. It produces high purity copper cathodes, copper drawing stock, industrial sulfuric acid, gold ingots, silver ingots, round copper wire, and cupric sulfate.
