| Abstract: | It has reelected raw ore which is 200 mesh occupied 60% by using 12 inches domestic centrifugal heavy separator in this paper.The result showed that the rate of recovery and stability of domestic centrifugal heavy separator was favorable.Moreover,the optimum conditions were determined by means of single factor experiment.The details can be described as follows: the obtained gold amount is 150 kg under 800 rpm of centrifugal force,20 L/min of recoil hydraulic and 120 min of accumulation time uninterruptedly run 60 h.The average gold grade is 671 g/t,and the recovery is 52.21%,in which the enrichment ratio is up to 583 times. |
