Economic Balance Of Copper Concentrates Plant

The selective leaching of copper from a gold–copper

copper in high percentages in a gold ore has negative effects on the efficiencyand economic viability of any goldprojectdueto (1)highcy-anide consumption in which copper will consume at least 2.3 kg of so-dium cyanide for every kilogramme of copper leached; (2) copper competing with gold in the adsorption/stripping circuit, which can ef-

Processing of Konkola copper concen- trates and Chingola

The characteristics of Konkola and Chingola concentrates —high copper (42% Cu), low sulphur (15% S), low iron (7% Fe) and high silica (10% Si)—render it necessary to blend the Konkola concentrates with other concentrates of higher iron and sulphur content, and to add limerock as a flux in order to produce a suitable feed for treatment in the Nkana
