4 Reasons and Solutions of Poor Gold Leaching Effect

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.
