Copper Cobalt Leaching

Glycine Leaching Processing for Orphaned Deposits QA

Glycine can leach most of the nonferrous transition base metals, specifically copper, but also nickel, cobalt and zinc. It is also capable of leaching the Precious metals under certain conditions, gold as well as silver, some of the platinum group metals, and finally lead under special circumstances.

Why the world is demanding more cobalt, and why new

Copper-cobalt ores are primarily found in Zambia and the DRC, where the cobalt is recovered from copper flotation concentrates, using a roast-leach-electrowin (RLE) process. The ore is roasted (for sulfides), followed by a sulfuric acid atmospheric leach, and direct electrowinning of copper.

FIG. 8 shows that leaching of cobalt was extremely rapid with the maximum extent of dissolution completed within 1 h. Copper leaching was somewhat slower and appears to continue beyond 24 h. The amount of nickel leached was smaller indicating that the reductive cure was not acting effectively on all nickeliferous phases.
