After examining the test, using a sediment sorting process, increased recovery rate from 93.05% to 95.01%,concentrate grade 135g / t up to 140g / t, stable production. Some gold as declining ore grade, thus making the flotation index lower, branch flotation process, improve flotation and ore concentrator grade. Of course, the flotation method and other methods is not a panacea, it is impossible for all the gold-bearing ores are effective, but also consider the nature of the ore mainly in the selection process, the need to carry out a wide range of demonstration and testing.

In the appropriate range, flotation machine impeller speed increases, reducing the depth of the trough, so that the impeller and the lid pull out such an increase in the gap measures inflated, can promote the flotation rate.as soon as possible so that the pulp through the flotation cell. Faster than the parallel tank tank series, but also conducive to enhancing flotation rate.selected slot size must be appropriate. Generally featured slot size is not too large. Featured trough is too large, so that the pulp residence time in the tank too long. Not only will froth depleted, and also reduced the flotation rate.

In recent years, the transformation process and pharmacy systems have added new progress, flotation recovery has improved markedly. In recent years,? Floating stage grinding machine process, heavy - floating joint process, etc., is currently China's main trends of the flotation process. Using heavy - floating joint process for stage grinding stage of selection, to obtain better indicator of recoveries increased by 6% or more. Direct ore flotation process for the former, because the higher mud (mud ore itself is high, coupled with mining tailings backfill strength is not enough, into the part of the sediment) a continuous decline in the ore beneficiation indicators.
