Extracting Gold From Arsenic Ore

Arsenic Pyrite Gold Extraction by Alkaline Leaching Oxidation

Gold recovery was proportional to arsenic extraction during the oxidative leach, with >90 pct Au extraction for arsenic extraction ≥ 89 pct. Silver extraction did not follow this trend and ranged from 47 to 62 pct. Cyanide consumption was 2.6 kg NaCN per metric ton of leach residue and 5.7 kg NaCN per metric ton for the untreated ore.

Extraction of gold from refractory gold ore using bromate

2019-06-01· Therefore, high-sulfur and high-arsenic carbonaceous refractory gold ore cannot be treated effectively using cyanidation alone. In this study, an efficient and low-toxicity method for extracting gold from a high-sulfur and high-arsenic carbonaceous refractory gold ore was developed using a solution of bromate and ferric chloride. The gold extraction rate for raw gold ore under

Extracting antimony from high arsenic and gold-containing

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.
