Embodiment 1
[0013] Sulfide mine tailings WO 3 0.08%, the graded cyclone grit and the graded cyclone overflow are obtained through the graded cyclone, the graded cyclone grit size is relatively coarse, +0.045mm particle size accounts for 40%, -0.045mm particle size accounts for 60% , grading cyclone sand settling and re-election by spiral concentrator to obtain tungsten spiral concentrate and tungsten spiral tailings, tungsten spiral concentrate shaker selection, obtain tungsten coarse-grained concentrate and tungsten shaker tailings; graded cyclone The overflow of the concentration cyclone enters the concentrating cyclone to obtain the grit of the concentrating cyclone and the overflow of the concentrating cyclone, and the concentrating cyclone is roughly separated by a centrifuge to obtain fine-grained tungsten concentrates and fine-grained tungsten tailings; combined Tungsten spiral tailings, tungsten shaker tailings and tungsten fine-grained tailings, through tailings cyclone to obtain...
