Abstract: The new type centrifugal separator was used to discarding the large number of tailings of tungsten ore from slims, and the next is that the gravity separation concentrate was put into the process of flotation. Of these mine samples, the degree of slimings is high and the particle size is very low, therefore the separation is very difficult. The experiment test through a flotation flowsheet of centrifugal -flotation was performed. The tungsten concentrate with the grade of 34.74 %WO3, and the total recovery of 75.21% can be obtained.
