Arsenic Pyrite Gold Extraction By Alkaline Leaching Oxidation

Jul 22, 2017 The rates of arsenic extraction for high-grade ore A in a 2M NaOH solution at 140 psig O2 were determined at 80 , 100 , and 140 C fig. 4. The rates for all three temperatures were rapid during the first 4 h of reaction. During the last 3 h, the extraction rate decreased at 140 C, and marginal rate increases were noted at 80 and 100 C.
