Ausenco support was provided during the construction and process plant commissioning phases. The Browns Oxide Copper Project which primarily produces copper and is also active in cobalt, …
Newmont and Gold Fields primary focus was the sulphide ore and their processing plants could not treat the oxide material and therefore it was stock-piled and never mined. We have already built a copper processing plant at a cost of US$4,1m and de-risked the project. We produced our first copper plates at 99,8856% purity (A-grade copper) with no
The flotation tailing then is thickened to about 40 percent solids and sent to the slime leach plant for extraction of copper from the acid-soluble oxidized copper minerals. The process has been described by Power. The slime plant consists of three 20-foot-diameter redwood leach tanks.
Copper ore processing. According to the metallurgy process, the copper ore is divided into three natural types by the ratio of copper oxide and copper sulfide. That is, sulfide ore, containing less than 10% copper oxide; oxidized ore, containing more than 30% copper oxide; mixed ore, containing 10% to 30% of copper oxide.
