Processing Gold Ores Using Heap Leach-Carbon

2016-8-17  The chemistry involved in the dissolution of gold in the heap-leach cya- nidation treatment is the same as that for the agitation-cyanidation process. In heap leaching, the oxygen, essential for the dissolution of gold, is intro- duced into the cyanide solution as it is being sprinkled upon the ore heap.

4 Reasons and Solutions of Poor Gold Leaching Effect

2020-6-22  If the gold ore is still difficult to be successfully leached after being finely ground, the gold ore is called refractory gold. Generally, the grade of Au in the tailings is greater than 0.5g/t. The gold in this type of ore, either physically wrapped or chemically combined, cannot be in contact with the cyanide solution, so it is difficult to be leached.
