| description | The invention discloses a method for recycling gold (III) in a waste circuit board leaching solution through tin disulfide, and belongs to the field of hydrometallurgy and precious metal recycling. The method comprises the following steps: recovering gold (III) in a solution by using tin disulfide, and adsorbing the gold (III) under mechanical stirring; the method specifically comprises the following steps: taking stannous sulfide dehydrate and thioacetamide as raw materials, preparing tin disulfide through a hydrothermal method, then preparing a waste circuit board leaching solution with a certain concentration, adding a certain amount of tin disulfide into the leaching solution, and carrying out gold adsorption under mechanical stirring; the method disclosed by the invention can be used for efficiently recovering the gold (III) in the aqueous solution, has better selectivity for recovering the gold (III) in the acid waste liquid, and has the advantages of energy conservation, environmental protection, low c |
