How to Improve the Refractory Gold Leaching Process?

2020-8-18 · Refractory gold ore refers to the part of gold ore that cannot be extracted effectively by the conventional cyanide leaching process after the fine grinding. The gold in this type of gold ore cannot contact with the cyanide solution due to physical encapsulation or chemical combination, resulting in a very low gold leaching rate.

AEROPHINE®

2021-10-26 · AEROPHINE Ⓡ promoters are the flotation reagents of choice when treating Cu/Zn, Cu/Pb/Zn and especially Cu/Au/Ag/Pb/Zn ores. These ore types frequently have very high levels of pyrite and other iron sulphides. AEROPHINE Ⓡ promoters are highly recommended over xanthates when selectivity against iron sulphides (pyrite, pyrrhotite and arsenopyrite) is required.
