Research on Flotation Test at a Certain Mine in Xinjiang

The property change of gold mining ore led to flotation reagents and ore properties mismatching,unstability of the production quota,and great fluctuation of the recovery rate of gold.Therefore,it was necessary to complete the reasonable laboratory test and whole process closed circuit experiment.According to process mineralogy characteristics of the ore and based on the traditional of sulphide ore flotation process,the method of rich sulfide was adopted combined with high efficientive flotation reagents,and we improved the recovery rate of gold sulfide ore of the valuable components.Meanwhile,the reasonable technological process,flotation reagents and flotation time were identified on the basis of the laboratory test.Gold recovery rate of mine ore with grade of6.5×10-6increased from 84% to 90%,and flotation gold concentrate grade was 60×10-6,tailings was 0.4×10-6.Under the condition that ore grade and the concentrate grade was constant,the experiment process was more environmental protection,flotation time was more reasonable and the recovery rate was higher,all of which not only created considerable economic benefits,but also saved the resources.
