Copper Processing: The Quest for Efficiency at Scale
There are two big opportunities for DES in copper processing: first, the processing of copper deposits in jurisdictions with water usage sensitives and, second, the processing via leaching of transition ores and copper sulphides. "As the DES process requires minimal water usage, we only use it as an option for washing," White said.

Copper Ore Production Process
In the crushing process of copper ore processing, the two-stage-closed-circuit crushing-single-stage ball milling process is more common in small copper ore concentrators whose production scale is below 500t/d. Three-stage crushing is currently the most crushing and grinding process used by large and medium-sized copper ore concentrators.

Copper-Nickel Ore Processing
Copper Solvent Extraction. The separation of copper from nickel is based on the fact that there is an appreciable difference in the pH at which the two metals are extracted. Copper can be extracted, with very small amounts of nickel, at pH 6.0 to 6.5, while nickel is extracted from the copper raffinate at pH 8.0 to 8.2.

Copper Ore Processing Methods
At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger concentrators has changed to such an extent that comparatively few of the machines in use at the beginning of the period remain in service today.
