Abstract

Abstract

In a concentrator in Xizang, the flotation flowsheet is one roughing three cleaning three scavenging, the copper grade of the raw ore is 0.85% and the copper oxidation rate is 6.14% . The copper recovery rate is about 88.79% , and the copper grade of the concentrate is 19.91% . In order to improve the recovery of copper, the flotation process structure of the concentrator was optimized by field investigation and small scale test, by adjusting the structure of flotation process to “partial rapid flotation + two roughing”, the recovery of copper was 92.18% and 3.39% higher than before. According to the test results, the flotation flowsheet was optimized and the recovery of copper was increased by 2.93 percentage points to 91.72%. The conclusion has important reference significance for the production of the same type of concentrators.
