Copper Sulfide Flotation - Mineral Processing & Metallurgy

Copper minerals usually occur in low grade deposits and require concentration prior to smelting. The method and degree of concentration depends on smelter location and schedules, together with the nature of the ore deposit. Sulphide copper ores generally occur with pyrite, pyrrhotite, arsenopyrite and molybdenite, and with gold and silver.

Extraction Of Copper From Sulfide Ore | MiningPedia

The content of copper and sulfide in the disseminated copper-sulfide ore is low, the copper-sulfide ratio is relatively large, and the ore generally contains 10%-40% pyrite. The gangue is unevenly infiltrated with copper minerals and pyrite, and some pyrites closely co-exist with copper minerals, and the aggregates have large particle sizes.

Segregation Process of Mixed Sulphide Copper Ore

Segregation Process of Mixed Sulphide Copper Ore. Sulphide copper ores are normally concentrated by flotation while the oxide ores undergo hydrometallurgical treatments. The mixed sulphide-oxide copper ores may be processed by combined methods such as flotation followed by leaching and precipitation of the oxidized portion, or vice-versa.
