Gold extraction - Wikipedia

OverviewHistoryTypes of oreConcentrationLeachingRefractory gold processesGold smeltingGold refining and partingGold 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. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of small gold nuggetsand flakes.

Carbon in pulp - Wikipedia

Carbon in pulp (CIP) is an extraction technique for recovery of gold which has been liberated into a cyanide solution as part of the gold cyanidation process.. Introduced in the early 1980s, Carbon in Pulp is regarded as a simple and cheap process. As such it is used in most industrial applications where the presence of competing silver or copper does not prohibit its use.

ACTIVATED CARBON IN GOLD RECOVERY - Kemix

In the gold recovery industry, activated carbon from a number of precursors has been used. Due to the nature of the in-pulp process, the following characteristics are important: High affinity towards gold – kinetic activity and equilibrium loading. Hard, resistant to abrasion. Density, suited to mixing in pulp.
