INVESTIGATING THE POTENTIAL OF Eriez Flotation

A number of tests were conducted on variety of copper sulphide ore samples. Fresh feed samples were ground in a rod mill to coarse size distributions, while plant samples were only screened to remove excessively coarse material. For each set of tests, a conventional rougher flotation test was conducted using a Denver laboratory flotation cell.
