Jun 01, 1992  When this carbonate elution technology was introduced in some Quebec gold mills, certain problems arose, however, which disturbed the elution and electrolysis circuits. These problems were accumulations of sediment in the circuit (scaling), fluctuations of the elution efficiency, increases in lost solu- hies and anode corrosion during electrolysis.

OPTIMIZING THE OPERATING CONDITIONS OF GOLD

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.
