Abstract

The present disclosure discloses an application of cuprous sulfide in a recovery of Au (III) from aqueous solutions, which relates to the fields of hydrometallurgy and precious metal recovery. The method of the present disclosure uses cuprous sulfide nanoparticles to recover Au (III) from aqueous solution, and undergoes gold adsorption under mechanical stirring. The method described in the present disclosure can efficiently recover Au (III) from aqueous solutions, has good recovery effects on Au (III) from acidic waste liquid, and has the advantages of energy conservation, environmental protection, and low cost.
