11/08/2020· The increased use of fertilizers from phosphates in agriculture generates water pollution by heavy metals contained in these phosphates at levels higher than the standards. In our study, we used a cadmium nitrate Cd(NO 3 ) 2 solution to simulate artificially polluted water, whose decontamination efficiency will be evaluated by an electrocoagulation/flotation process.

To make the flotation process commercially efficient, physicochemical properties of the ore must be determined and the amount of chemical consumption must be tuned to reduce the costs for production higher grade of concentrates at maximum recovery (Mehrabani et al., 2010). In addition in galena flotation it is important to completely remove the zinc in lead concentrates

Simultaneous optimization of flotation column performance using genetic evolutionary algorithm 877 Venter et al. (1997) proposed an approach from the field of GA for flow sheet design.
