Effect of grinding media on zinc depression in a lead ...

2009-8-1  As the chrome content of the grinding media increased, and the mill pulp chemistry environment became more oxidising , the lead flotation rate, grades and recoveries noticeably reduced. A main reason for the drop in lead flotation performance was found to be poor selectivity for galena against sphalerite and non-sulphide gangue minerals.
