Extracting antimony from high arsenic and gold …

2019-6-1 · 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.Stripping chrome in an electrolytic bath - Practical Machinist · Chrome can be removed in a caustic soda and water solution, at 140 degrees F, at 10-12vdc.
