carbon for processing Copper and gold

Control Copper in Carbon Adsorption and Gold Recovery Circuits

23.05.2018  Carbon is stripped in a standard pressure strip using only caustic soda, temperature, and pressure to elute the gold. A single- pass electrowin circuit removes gold from the strip pregnant solution before it returns to a strip barren tank for reheating and reuse. Carbon Adsorption Details

Carbon Adsorption of Gold

04.10.2018  This gold feed solution was fed by a metering pump at a rate of 2.5 ml/min. to each carbon loading column. The feed solution was analyzed for gold, silver and copper to monitor potential interference to gold loading. A gold/cyanide solution was prepared in the same manner as previously stated.

Activated Carbon in Gold Cyanidation

Activated carbon is a critical component in the beneficiation of gold ore, allowing this widespread process to occur because of its ability to recover gold from the gold-cyanide complex. Depending on the deposit, some silver ores may also be processed via cyanidation. Here too, activated carbon is the catalyst for recovery of this precious metal.

Production of Gold - West Virginia University

Gold is adsorbed onto the activated carbon. The filtrate is then sent to the elution vessel, V-401, where the elution process begins. The gold is eluted into a water solution from the carbon by the American-Anglo Research Laboratories (AARL) method, leaving the barren carbon behind. Figure 5 shows the carbon adsorption and AARL elution ...
