Extracting antimony from high arsenic and gold-containing

Jun 01, 2019 · Antimony extraction reached over 98%, the average extraction of Fe, As, and Au were 5.50%, 1.14%, and 0.63%, respectively. Gold and aresenic remained in the leaching residue, which was further used as a raw material for gold extraction. Thus, the separation of antimony from gold and arsenic was achieved.
