2009730In 1972 Inco Europe Ltd.4installed asolvent extraction SX process for the refining of gold using dibutyl carbitol DBC as the extractant. Although the selective extraction of gold from chloride media using DBC is favourable stripping requires direct precipitation of gold from the loaded organic phaseresulting in high organic losses.

Gold Solvent Extraction SX Kinetics. 2006628 Gold Solvent Extraction Reduction Process Gold can be leached from various feed materials by hydrochloric acid under oxidiing conditions and recovered by solvent extraction followed by direct reduction with a chemical reductant to granular metallic gold.
Materials
In some cases high recovery of gold by flotation is accompanied by high levels of pyrite flotation resulting in a lowgrade copper concentrate for treatment. Smelting of lowgrade concentrates incurs significant economic penalties in shipping of concentrates to smelters unit deductions in smelter contracts and treatment and refining costs.
Materials
Sulfide minerals are impermeable minerals that occlude gold particles making it difficult for the leach solution to form a complex with the gold. Organic carbon present in gold ore may adsorb dissolved goldcyanide complexes in much the same way as activated carbon. Electrolytic Refining Silver Gold

Operation of the electrowinning process differs depending on the elution procedure that is used. In the case of Zadra elution where the electrowinning cell is in series with the elution column the column and cell must be designed to elute and recover the gold by recirculation of the eluant until the gold content of the eluted carbon is low enough 100 gt to be reactivated and returned to

2020229Electrowinning processes can also be used for wastewater treatment and general recycling. The principle is still the same any impure material can be leached into a conducting solution then the DC voltage is applied through the solution and the desired material can be extracted of course there are certain limitations such as metal concentration temperature acidity levels chemical
