4. Beneficiation of Copper 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 material called concentrate is then sent to the smelter.
Sulfide Ore - an overview | ScienceDirect Topics
Beneficiation of complex base metal sulfide ores is based on selective production of individual clean concentrates of copper, zinc, and lead. Sphalerite flotation through copper activation becomes complicated when other minerals such as pyrite can get inadvertently activated.
Sulfide Ores - an overview | ScienceDirect Topics
Sulphide ores were mostly created by (i) the intrusion of molten magma from the mantle into the crust of the earth and (ii) the formation of localized metal-rich sulphide ore bodies by sequential solidification and/or hydrothermal leaching and precipitation.
