LEACHING OF COPPER CONCENTRATES

LEACHING OF COPPER CONCENTRATES

copper recoveries can be made in the leach, the economic necessity of limiting oxidation of sulfur suggests that a multi-stage leach procedure recovering about 50 per cent per stage is desirable. ChalCocite final concentrates, rougher concentrates, and ores were tested. These leached more readily than chalcopyrite concentrate.

Copper Mining and Production Processes Explained

Copper Mining and Production Processes Explained

Leaching offers an alternative to copper mining. First, the ore is treated with dilute sulphuric acid. This trickles slowly down through the ore, over a period of months, dissolving copper to form a weak solution of copper sulphate. The copper is then recovered by electrolysis. This process is known as SX-EW (solvent extraction/electrowinning).

The leaching, solvent extraction and electrowinning (LX-SX-EW) process is a widely used method in the production of copper from low-grade oxidized ore. Copper is the most common metal to be processed by LX-SX-EW, but the process can also be used to extract, purify and concentrate other metals, such as nickel, cobalt and zinc.

Heap leaching is the method most commonly chosen for copper recovery from oxide ores. An acidic solution is used to leach the metal, dissolving the copper into what is referred to as a pregnant leach solution (PLS). This solution is collected and purified by solvent extraction (SX). SX is a two-step process of loading the copper into an organic ...
