Integration of jkmsi and oxidation index to determine flotation behaviour of sulphide ores

This paper compares the use of the JKMSI technique and the Oxidation Index methodology to evaluate the change in flotation performance of Cu-Zn complex sulphide ore samples treated with hydrogen peroxide to generate artificially different levels of oxidation and thus ore floatability. The objective of the work is to compare the consistence of the two techniques to measure the variability of ore floatability to get a quick response for the estimation of flotation performance. The results showed that JKMSI can be incorporated in the current Oxidation Index methodology and both techniques have the potential to replace the standard batch flotation tests under certain conditions for geometallurgical ore characterisation programmes. This test uses much less material and much faster than a standard batch scale flotation test. However, both techniques is still have some limitations and further work is required for their improvement.
