Effect of waste rock dilution on spodumene flotation

May 01 2020 0183 32 The effect of waste rock minerals introduced by dilution on the flotation of spodumene was investigated The objectives of this work were to investigate how flotation yield and grades deteriorate mainly by Mg-bearing biotite and amphiboles that are introduced to the system by waste rock dilution and find the possible ways to improve the flotation performance regarding these Mg-bearing minerals...
