Electrolytic recovery of antimony from natural stibnite ore

1996-11-1  The solution was boiled for about 30 min to dissolve the sulphates of iron and non-ferrous metals completely. The insoluble residue was filtered and washed well with 1% H2SO4 solution. 2.4. Preparation of antimony complex salt ore electrolytes Antimony exists in the leach liquor as trichloride, which forms antimony oxychloride with water.

Extracting antimony from high arsenic and gold

This study investigated the leaching and electrowinning of antimony from a complex, high arsenic and gold-containing stibnite concentrate ore (As-Au-Sb ore) using slurry electrolysis (SE). The results indicated that the leaching efficiency of antimony was higher than 98%, and those of iron and arsenic were about 5.50% and 1.14%, respectively.
