4. Beneficiation of Copper Ore

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 material called concentrate is then sent to the ...

Copper processing - Ores | Britannica

Copper processing - Copper processing - Ores: Principal forms in which copper ores are found include native copper, porphyry copper, massive deposits, and mixed ores. Native copper is simply the metal found unadulterated in nature. Occasionally copper is still found in its native form, but more frequently it is mixed with other minerals, some of which may have value themselves.

Copper extraction - Wikipedia

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).
