gold extraction elution plant


Carbon in pulp - Wikipedia

Carbon in pulp 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 acts like a sponge to aurocyanide and other complex ions in solution. Hard carbon particles can be mixed with the

Gold Elution Systems – Protherm Systems

Gold Elution Systems Strip solution (Elution) Heating Systems Protherm Systems are actively involved in the design manufacture supply of pre-assembled and skid mounted gold elution plant and have supplied many such installations to the gold mining industry. Elution systems and equipment suitable for both ZADRA and AARL elution processes

High Efficiency Elution and Electrowinning Plant for Gold

High Efficiency Elution and Electrowinning Plant for Gold 1.1 Elution CN- or OH- dissolved in desorption solution is easier than Au(CN)2- to be absorbed by the activated carbon which causes Au(CN)2- absorbed on loaded carbon is replace by CN- or OH- and the reversible balance of of gold adsorption is broken.

Elution and Carbon Reactivation - Resource book

Elution Elution is the actual gold removal stage. Potable water (low ionic strength) is pumped through the column at high temperature (115°C) and pressure (230 kPa). High temperatures are used as the gold loading capacity of carbon is reduced with increasing temperature.
