Extracting antimony from high arsenic and gold …
The antimony extraction rate was calculated using the relation (1) α = m 0 × x 0 − m 1 × x 1 m 0 × x 0 × 100 % where α is the extraction rate (%) of antimony, m0 is the initial weight (g) of the ore, x0 is the Sb content (wt%) in the ore, m1 is the weight (g) of the leaching residue, and x1 is the Sb content (wt%) in the leaching residue. 2.2.
