Normal inputs apart from the leaching and adsorption parameters were the feed rate of ore, the per cent solids in the slurry, the carbon advance rate and the residual loadings of the regenerated feed carbon.

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.
