Experimental Study on Improving the Rate of Antimony Ore Grade and Recovery of Mineral Processing

In order to improve the grade and recovery of antimony, antimony ore in the process of flotation, this exploratory experiment by reagent addition, process selection to realize. The main parameters of the first set of experiments; grinding fineness of 70% lead nitrate, 200g, Black Powder 100g, directly add collector, did not add kerosene decarburization, choose a coarse, two sweep, two fine flotation process; and the second group of experiments the main parameters; grinding fineness of 70% 200g, lead nitrate, xanthene’s, the choice of a coarse, two sweep, two fine flotation process. The combination of two different groups of flotation experiment comparison, makes the antimony ore grade and recovery can be increased.
