Improvements in Copper heap leaching by use of wetting agents

tive effect on the copper extraction rate in heap leaching independently from the pre-treatment of the ores. This confirms the hypothesis that an increased productivity of a hydrometallurgical cop- per-plant can be achieved by using tailor made wetting agents. Introduction. Generally copper ores are classified into sulfidic and.

Optimal design and planning of heap leaching process. Application .

Although the process of heap leaching is an established technology for treating minerals, such as copper, gold, silver, uranium and saltpeter, as well as remediating soil, no studies to date have investigated process optimization.
