Copper production environmental impact

Copper production environmental impact

The solvent extraction process specifically generates a "sludge," or, as it is known in the copper industry, "crud" or "gunk." Sludge is periodically removed from the system, and centrifuged or otherwise treated to remove the organics. The aqueous solutions and the solids are disposed of and the organics are returned to the solvent extraction circuit for reuse. Depending on the characteristics ...

In the extraction of copper from its sulphide ore, when ore is subjected to roasting, some of it is oxidised to Cu 2 O which reacts with the remaining Cu 2 S (sulphide ore) to give copper metal. Cu 2 S +2Cu 2 O → 6Cu +SO 2 ↑ In this process, Cu 2 S behaves as reducing agent.
