Extracting antimony from high arsenic and gold-containing

01/06/2019· Gold and arsenic were present in pyrite and arsenopyrite, which were stable during the SE and were retained in the leaching residue. This laid the theoretical basis for separating antimony from gold and arsenic in the As-Au-Sb ore by SE. All the reagents were of analytical grade, and all the aqueous solutions were prepared using distilled water.

Extracting antimony from high arsenic and gold-containing

The SE selectively leached antimony, while gold and arsenic were retained in the residue as a raw material for further gold extraction. The antimony content in the cathode antimony was >98%, and arsenic content was less than or equal to 0.21%.
