Abstract

According to the test results, the flotation process parameters of refractory zinc oxide ore will be optimized by the response surface methodology in this paper. The regression model between Zn recovery and sodium sulfide concentration, depressant(F1) concentration and sodium carbonate concentration was established. It can be known that the model is highly significant and test error is very small, and the concentration of sodium sulfide has great influence to the recovery of Zn concentrate. The verification tests results show that the model is reliable and can predict accurately the zinc recovery. It can be concluded that the optimizing process parameters are sodium sulfide 7500g/t, depressant concentration 1050g/t, and sodium carbonate concentration 2200g/t, which can provide the technical basis for the comprehensive utilization of low grade refractory zinc oxide ore.
