4 Reasons and Solutions of Poor Gold Leaching Effect
22/06/2020· Therefore, during cyanide leaching process, it is difficult for the cyanide solution to contact with gold mineral, so the gold leaching rate is often low. Solution. After reaching a certain degree of monomer dissociation, for gold ores with low arsenic content, aqueous solution oxidation, aqueous chlorination, bacterial oxidation, etc. can be used. For the gold ore or concentrate with high,Still Using Cyanide to Extract Gold? You Are Out! | CNFREE,05/09/2018· According to data disclosed by the listed gold mining companies in industry association, more than 1 million tons of various gold extraction reagents were consumed per year on gold mine reagent companies’ comprehensive analysis, with the output value of about 15-30 billion RMB.
