Abstract

Flotation tests were carried out with the aim of investigating the effects of several depressant reagents on the concentrate grade recovery from mixed ore circuit at First Quantum Minerals (FQM) Kansanshi mine. These tests were performed on laboratory scale using Deptanes 90, 280,490, and 590 as depressants. Of all the reagents tested, Deptane 490 and Deptane 280 showed significant improvement in concentrate grade in comparison to other reagents investigated. The optimum dosages for both Deptane 490 and Deptane 280 were 80g/t achieving approximately 38% and 29% grade recoveries, respectively.
