Abstract: The gold and silver grade of a gold-bearing copper ore from Yunnan is low and the gold and silver are distributed inhomogenously,leading to the gold content of copper concentrates obtained from the flotation of the ores in the ore section with low-grade raw ores failing to reach the valuation standards,lowering economic benefits of enter-prises.The paper carried out mineralogical study and small-scale experimental study,investigated the flotation flowsheet,analyzed the causes of existing problems,and constantly optimized and renovated the process based on field production conditions.As a result,in the premise of gold in copper concentrate reaching the valuation standard,gold recovery rate gradually increases,with that of 2016 reaching 68.94 %,which,compared to 55.33 % of 2015,is 13.61 percentage points higher,making significant economic profits.
