Response Surface Methodology for Copper Flotation Optimization …
Response surface methodology (RSM) is one of the most effective tools for optimizing processes, and it has been used in conjunction with the Analysis of Variance (ANOVA) test to establish the effect of input factors on output factors. However, when this methodology is used in mineral flotation, its polynomial model usually performs poorly. …

Flotation surface chemistry of water-soluble salt minerals: from
Unlike DAH and SDS, SL exhibits the opposite flotation selectivity. As seen in Fig. 1 c, only NaCl is floated with SL at a concentration higher than its solubility limit, while KCl cannot be floated over the whole concentration range. Noticeably, the floatability of NaCl with SL is relatively weaker, with a maximum NaCl recovery of about 70% compared to …
