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.
