Separation of gold from lead-rich minerals for neutron-activation analysis.
An easy method for the recovery of gold from lead-rich minerals has been developed. The gold is extracted with methyl isobutyl ketone from an aqua regia solution of the mineral, then stripped into aqueous medium by evaporating the solvent, and finally co-precipitated with lead sulphide. The gold is uniformly distributed in the lead sulphide.
