Research on Sulfur-arsenic Separation Process of a Refractory Gold Ore Containing Arsenic and High-sulfur

With the process of selective flotation sulfur and arsenic and then magnetic separation,the tests of sulfur-arsenic separation were carried on in acidic conditions for a refractory gold ore containing arsenic and high-sulfur.By close-circuit experiment,high-quality sulfur concentrate and arsenic concentrate containing gold were obtained respectively,and sulfur and arsenic were separated effectively.At the same time,the recovery of gold was improved.
