kolkata the process to concentrate copper

how is copper concentrate process

Most copper ore currently being mined contains copper mainly as chalcopyrite. Since chalcopyrite by itself is only about 35 percent copper, it is difficult to upgrade a concentrate by flotation to more than about 25 to 28 percent copper without losing a significant amount of copper during the cleaning steps.

How to Concentrate Copper | Science

Dec 19, 2003· P orphyry copper deposits supply nearly 60% of the world's copper ([1][1]). They form as magmas in the upper crust, cool, crystallize, and exsolve metal-bearing hydrothermal fluids that precipitate copper sulfide minerals. The deposits have been studied for over a century, revealing a strikingly constant spatial and temporal relationship between copper-bearing hydrothermal veins and …

MINING TO SMELTING - GOLD/COPPER CONCENTRATES IN …

Copper concentrate smelting is a large scale, intensive process consisting of four stages: sulphur in the sulphide minerals is "burnt-off"; the metals are melted to form a "matte" and the waste material forms a "slag"; copper in the matte is electro-refined to copper metal; and the gold/silver is refined to doré.
