Copper Ore Complete Concentrating Method

Spectrophotometric Determination Of Copper

Copper smelting and classification The smelting of copper Copper that is mined from copper ore, after beneficiation, becomes high quality copper concentrate. Then, after being smelted, refined copper and copper products are yielded. There are two ways of smelting copper, one is pyrometallurgy, the other hydrometallurgical.And concentration (or beneficiation) of a metal from the earth. Proposed mining projects differ considerably in the proposed method for extracting and concentrating the metallic ore. In almost every case, metallic ores are buried under a layer of ordinary soil or rock (called ‘overburden’ or ‘waste rock’) that must be moved.
