Abstract: Disclosed herein are methods for obtaining a composition comprising copper sulfide from a material, wherein the methods comprise: contacting the material with an acidic aqueous solution having a pH less than 6 in the presence of sulfur dioxide to form copper sulfide; wherein the material comprises one or more copper compounds chosen from copper in a zero oxidation state, copper oxide, and copper hydroxide, and wherein the material comprises an amount of zero oxidation state metals having a standard redox-potential less than zero volt versus a standard hydrogen electrode. Also disclosed are methods for recycling at least one battery material, and compositions comprising copper sulfide.
