Model For Heap Leaching Of Gold Ores By Cyanidation

Jan 01, 1997 The purpose of this article is to develop a model of the heap leaching process for the extraction of gold from non-refractory ores considering the omissions made by other authors. The model should, therefore, consider the effects of the transport mechanisms and employ a kinetic expression adequate for gold cyanidation.

Ultimate Guide Of Gold Heap Leaching Process Miningpedia

Mar 27, 2020 In the short-term gold heap leaching process, the ore is usually crushed to less than 20 mm. When processing gold-bearing quartz veins, it is often crushed to less than 6 mm. The crushed ore heap is leached on a permanent bottom mat, with stack height of generally 3-6 meters, per heap processing volume of 100-10000 tons, and per heap leaching cycle of generally 7-30 days.
