Acid leaching is a clean and effective method for the decomposition of sulfide. As shown in Fig. 1 (Xiao et al., 2021b), NiS, Ni 3 S 2, FeS, and MnS could react with H + at pH 0 and convert to Ni 2+, Fe 2+, and Mn 2+ along with the release of H 2 S. For CuFeS 2 or CuS, a solution of high acid concentration is necessary to produce the decomposition …
