Oxide copper ore, mixed oxide-sulphide ores and low-grade copper sulphide ore, which, for economic reasons, cannot be enriched by flotation, may be processed by leaching methods. Agents for leaching copper can be acid, base, or salt solutions. Of all of these agents, sulphuric acid has been given the
Get MoreCopper oxide ores are mainly malachite and azurite, followed by chrysocolla and cuprite, copper sulfate and other soluble salts of copper. Malachite Cu2CO3(OH)2 Malachite ore can be beneficiated by sulfurization floatation (vulcanization flotation). First, the surface of malachite ores is pre-sulfurized with sulfides such as sodium sulfide and ...
Get MoreCopper Sulfide Ore. About 80% of the world's copper-from-ore originates in Cu-Fe-S ores, such as chalcopyrite (CuFeS2) and chalcocite (Cu2S). The concentration of these minerals in an ore body is low. Typical copper ores contain from 0.5% Cu (open pit mines) to 1 or 2% Cu (underground mines). Cu-Fe-S minerals are not easily dissolved by ...

Get MoreThe recovery of copper from oxide ores containing from 2% to 4.1% acid-soluble copper from the Sarcheshmeh mine in Kerman province of Iran was investigated by agitation leaching in sulfuric acid media. Quartz, as a major constituent, and malachite, as the major copper mineral, were identified in the ore by X-ray diffraction (XRD) and microscopic studies. A series …
Get MoreCopper sulfide and oxide ores are the forms most commonly mined for copper. Copper Ores. Copper ores are complex. Can contain metals, other elements, and non-metallic minerals. In the ore, copper is . less than 1%. Depending on the ore, it requires different mining and extraction processes to yield .
Get MoreCopper ore beneficiation methods. Before the beneficiation of copper ores, crushing and grinding are required. The bulk ores are crushed to about 12cm by a jaw crusher or a cone crusher. Then the crushed materials are sent to the grinding equipment, and the final particle size of the copper ore is reduced to 0.15-0.2mm.
