Abstract: The gold grade of cyanide tailings from a gold mine in Liaoning is 2.01 g/t,with a silver grade of 36.23 g/t,copper grade of 0.33 %,lead grade of 1.91 %,and zinc grade of 3.01 %.Copper-lead-zinc mixed flotation tests and tests on preferential separation of lead-zinc flotation from the tailings were conducted on the cyanide tailings.The copper-lead-zinc mixed flotation test yielded a mixed concentrate with gold grade of 13.72 g/t,silver grade of 281.70 g/t,copper grade of 3.63 %,lead grade of 16.01 %,and zinc grade of 36.92 %.The recovery rates for gold,silver,copper,lead,and zinc were 50.09 %,57.22 %,80.69 %,61.33 %,and 90.88 %,respectively.The process of preferential separation of lead-zinc flotation from the tailings produced a lead concentrate with a grade of 48.95 % and a recovery rate of 52.29 %,and a zinc concentrate with a grade of 43.21 % and a recovery rate of 89.45 %.In the lead concentrate,the gold grade,silver grade,and copper grade,were 54.02 g/t,891.42 g/t,5.92 %,respectively.In the zinc concentrate,the gold grade,silver grade,and copper grade,were 2.43 g/t,134.79 g/t,and 2.19 %,respectively.The total recovery rates for gold,silver,and copper were 62.39 %,73.43 %,and 77.76 %,respectively.The separation indices were favorable,providing a reference basis for the comprehensive utilization of similar cyanide tailings resources.
