摘要： This application pertains to methods of recovering metals from metal sulfides that involve contacting the metal sulfide with an acidic sulfate solution containing ferric sulfate and a reagent that has a thiocarbonyl functional group, wherein the concentration of reagent in the acidic sulfate solution is sufficient to increase the rate of metal ion extraction relative to an acidic sulfate solution that does not contain the reagent, to produce a pregnant solution containing the metal ions.

摘要： 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 aquesous 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.

摘要： A method of separating scandium from a feedstock wherein a scandium enriched solution is produced from the feedstock and the scandium enriched solution is extracted to produce an organic phase of the scandium enriched solution. The organic phase of the scandium enriched solution is re-extracted to produce an aqueous phase including scandium chloride. The aqueous phase is precipitated and calcinated to produce scandium oxide powder.

摘要： The present disclosure relates to a method for extracting lithium from a lithium-containing material. For example, the method can comprise leaching a roasted lithium-containing material under conditions suitable to obtain an aqueous composition comprising a lithium compound such as lithium sulfate and/or lithium bisulfate. The aqueous composition comprising lithium sulfate and/or lithium bisulfate can optionally be used, for example, in a method for preparing lithium hydroxide comprising an electromembrane process. The roasted lithium-containing material can be prepared, for example by a method which uses an aqueous composition comprising optionally lithium sulfate and/or lithium bisulfate which can be obtained from a method for preparing lithium hydroxide comprising an electromembrane process such as a two-compartment monopolar or bipolar electrolysis process.
