Investigation of silver extraction from a silver-sulphur ...

A thiourea leach extracted only 24% of the silver, partly because silver re-precipitation occurred. It was evident that some form of pretreatment was needed to make the silver amenable to leaching. Pressure oxidation with sulphuric acid at 200°C dissolved 56% of the silver in 4 h provided an initial acid strength of 90 g/L was used.
