Gold extraction process method for cyanide tailings containing primary sulfide-coated gold
A method for extracting gold from cyanide tailings containing primary sulfide-coated gold , firstly separating and enriching the primary sulfide containing gold in the cyanide tailings by flotation, and then depositing the gold-containing sulfide concentrate The ultra-fine grinding in the tower type grinding machine, after ultra-fine grinding, enters the enhanced alkali immersion stirring tank to carry out alkaline pre-oxidation at normal temperature and normal pressure. After the pre-oxidation is completed, CaO milk is added to the slurry to adjust the slurry, and the cyanide leaching is carried out after the slurry is adjusted. Homework, efficient gold withdrawal.
