摘要
The invention relates to a method for recovering gold by solvent extraction from an acidic chloride containing aqueous solution or from slurry containing gold-bearing solids using a diester based reagent that is poorly soluble in water as organic extraction solution. In accordance with the method, gold is extracted extremely effectively, but other precious metals and many other metals quite sparingly. Gold is stripped from the extraction phase with pure water, from which the gold can be reduced either chemically or electrochemically.
