Jul 13, 2022· 1 Wash, filter and grind the granite ore with into smaller pieces. 2 Put the ground ore into a tank containing a dilute cyanide solution and add zinc. The chemical reaction between a dilute cyanide solution and zinc will separate the gold from the ore. 3 Use a filter press to remove the gold from the solution.

Abstract 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% ...
