| Abstract: | Based on analysis on the dosage of sodium cyanide and research on its leaching mechanism in gold concentrate leaching,a new technique that the mixture of ammonium carbonate and ammonium hydroxide can reduce the dosage of sodium cyanide is put forward.Industrial application shows that with this technique,the dosage of sodium cyanide can be reduced by more than 50%,manufacturing cost by more than 30%,the grade of silver slag by 15g/t,while the extraction rate of silver can be enhanced by 11%. |
