Processing technology of flotation tailings by using combined flotation reagents

We tested technologies of processing of flotation tailings by using combined flotation reagent on the example of tailings from Zhezkazgan plant and Tishinskoe deposit (Kazakhstan). The combined collector is a mixture of composite aerofloat, TS-1000 and butyl xanthate with reactant ratios 1:1:3. The advantage of the suggested flotation reagent is its composition including two polar groups and a long hydrocarbon radical. We showed that the flotation of Zhezkazgan tailings using smaller consumption of combined reagent in comparison with butyl xanthate resulted in the draft copper concentrate with copper content 13.0 % at recovery 80.22 %. In comparison with the base technology the content of copper in the draft concentrate increases at 5.1 %, and the recovery - increases at 31.4 %. At flotation of Tishinskoe deposit tailings the copper recovery into the collective concentrate increases at 9.63 %, lead - at 8.41 %; zinc - at 9.2 %.
