Polythionite
WebProcesses are provided for recovering precious metals from refractory materials using thiosulfate lixiviants. The processes can employ lixiviants that include at most only small amounts of copper and/or ammonia and operate at a relatively low pH, reduction of polythionates, inert atmospheres to control polythionate production, and electrolytic … WebOct 9, 2015 · This is far superior to that of materials with low affinity for LiPSs (e.g. Super P carbon, which exhibits a 42% loss under the same conditions). 69 Furthermore, the thiosulfate-polythionate conversion may also account in part for the excellent properties of another Li-S host material, graphene oxide, based on observation of the same thiosulfate …
