 — 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.

Isotopes of Antimony. It has two stable isotopes, antimony-121 and antimony-123. These isotopes have almost same natural abundance, 57.36% (Sb-121) and 42.64% (Sb-123). There are thirty-five radioactive isotopes of antimony, and among them the most stable isotope is antimony-125 that has a half life of 2.75 years. REFERENCES [1]. Harper, …
