摘要
A process for the extraction of silver and gold from refractory ore is disclosed. The process includes first grinding the refractory ore. This ground refractory ore is subsequently treated with an alkali solution of a stoichiometric excess amount of sulphide in relation to the amount of gold and silver contained in the refractory ore, to thus form a pulp containing a gold and silver sulfide. The pulp and alkaline solution ore are aerated to oxidize the excess sulfide to sulfate and then a mixture of the pulp and cyanide liquor are formed. Finally this mixture is aerated to obtain a final gold and silver product.
