Research on the floatation of willemite

The flotation of willemite has been studied by the methods of flotation with kinds of collector as fatty acids,and based on the tests of grinding,do sage of Na₂CO₃,(NaPO₃)₆, C_USO₄,oleic acid and Different types of activator,the proper do sages of agents were obtained. The experimental results show that the methods of flotation with kinds of collector as fatty acids can effectively achieve the silicon zinc mine flotation, in 10.2% under the condition of ore grade, concentrate zinc grade reached 45.03%, flotation recovery rate 81.05%.WT
