Gold extraction refers to the processes required to extract gold from its ores. This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.
Preg-robbing: Any microscopic carbon material in the ore will compete with the activated carbon to adsorb Au out of the cyanide solution, and prevent recovery (so called preg-robbing). Several other clay type minerals will have the same effect.
Gold recovery increase in CIL circuit. Various trials have shown the potential of PIONERA BioPolymer to increase metal recovery in leaching circuits. This is especially relevant in the CIL/CIP circuits used in gold processing. The benefit of PIONERA BioPolymer is also observed in the Merrill Crowe process.
Unlike alluvial gold, which is found as very small flakes on river banks, gold-bearing rocks have to be dug out of the ground. We want pure gold, but gold-bearing rocks include lots of other materials such as quartz, calcite and the sulfides of other metals.
