process copper and silver are not recovered for resale. This has prompted interest to also recover copper by se-lective metal sulphide precipitation. The copper sulphide precipitate is then recovered by conventional clarifica-tion and filtration to produce a filter cake (45% to 60% Cu) which can be shipped to a copper smelter.

31-08-2016· The silver was recovered by precipitation on detinned scrap iron. A modification of the Holt-Dern process was used at the Achotla chloridizing mill of the Cia Minera de Penoles in Guerrero, Mexico. Here the mixture of oxide ore, sulphide ore, and salt (3.3 per cent of the charge) was given a chloridizing roast in 16 Holt-Dern blast roasters.
