The ore sample used contained 2.03% Cu, 0.15% Co, and 3.73% S. The valuable minerals present were chrysocolla, chalcopyrite, and native copper. The gangue comprised pyrite, carbonate, calcite, and clay minerals. The ore (of a size up to −149 μm) was beneficiated using the sulphidisation and xanthate flotation method.

Beneficiation of Iron Ore and the treatment of magnetic iron taconites, stage grinding and wet magnetic separation is standard practice.This also applies to iron ores of the non-magnetic type which after a reducing roast are amenable to magnetic separation. All such plants are large tonnage operations treating up to 50,000 tons per day and ultimately requiring …

Copper exists in nature mainly in the form of sulfide ores and oxide ores, of which sulfide ores are the most important, while the slow oxidation and metamorphism of sulfide ores generate oxide ores. Among them, oxidized copper ore refers to copper ore with an oxidation rate greater than 30%.It is generally located in the oxidation zone above the ore bed, which has …

Beneficiation of Copper Ore. Top: Slurry tanks for sulfide ore. Bottom: Leach field for removing copper from oxide ore. Sulfide ores are mixed with water and special chemicals creating a slurry. The slurry, when agitated causes the copper sulfide minerals to float at which point they are skimmed off the surface and eventually dried. The dried ...
