Experimental Study on Key Integrated Technology for Comprehensive Utilization of Antimony-Arsenic-Bearing Gold Concentrate
Direct cyanidation test,two stage roasting cyanidation test,direct cyanidation-flotation recovery of antimony-flotation tailings two stage roasting cyanidation test were carried out for a gold concentrate containing antimony and arsenic.The results show that the primary direct cyanidation,the secondary cyanidation tailings flotation enrichment of antimony concentrate,and the third stage two-stage roasting cyanidation of antimony flotation tailings are the key integrated technical methods,the leaching rate of gold and silver from gold concentrate containing antimony and arsenic is 31.22％and 85.19％,respectively.Antimony concentrate with antimony content of 38.80％is produced from cyanide tailings flotation.The concentrate yield is 10.50％and antimony recovery is 90.94％,the recovery of gold,silver and antimony from antimony flotation tailings by two-stage roasting is 90.07％and 52.70％,respectively.The comprehensive recovery of gold,silver and antimony is 93.56％,92.99％and 90.94％,respectively,the comprehensive recovery effect of valuable metal resources is obviously improved,and the high-value and resourceful utilization of antimony-arsenic-bearing gold concentrate is realized.
