Abstract :
In order to solve some issues of Cu-Fe sulfide flotation separation at high basicity, the experiment on flotation separation of Cu-Fe sulfide at low basicity for a Cu-Ag multi metal ores in Jiangxi province used the DT series depressor of Jiangxi University of Science and Technology. The results showed that flotation separation of Cu-Fe sulfide with the depressor DT-2* at low basicity of pH=8, the grades and recoveries of copper and sulfur concentrates were 22.49%,33.07% and 88.76%,62.25% respectively. Meanwhile, the silver grade and recovery are 1391.6 g/t and 71.59% in the copper concentrate.
