Gold extraction - QueensMineDesignWiki

2019-6-28 · The first step in gold extraction is leaching the gold which turns gold in solid form to liquid with cyanide in the presence of oxygen. Next, the gold adsorbs to the activated carbon. Finally, the carbon and gold complex is sent to elution where it is washed, and transferred to electrolysis where the gold is fully recovered.

AMIT 135: Lesson 6 Grinding Circuit – Mining Mill

Size reduction by crushing has a size limitation for the final products. If further reduction is required, below 5- 20mm, grinding processes should be used. Grinding is a powdering or pulverizing process using the rock mechanical forces of impaction and attrition. The two main objectives for a grinding process are:
