— In solution containing HCl or H 2 SO 4 and NaCl, metal oxides react with leachate to form chloride salt, and then enter the leach solution as arsenic chloride (AsCl 3), antimony chloride (SbCl 3), and bismuth chloride (BiCl 3). Precious metals are enriched in the residue and separated from other valuable metals.
