A tungsten ore processing plant applies graded coarse floatation technology and fine particle flotation to process sulphide ore. Some wolframite monomer are floatated by magnetic separation. Sorting tailings are grinded to monomer dissociation. Sulfide ore, wolframite and cassiterite are processed consecutively. All copper sulfide ore concentrate on sulfur separation process for the purpose of coarse ore mineral sorting. Tungsten concentrate WO3 grade≥60% (the recovery rate≥88%), copper concentrate grade≥24% ( recovery rate≥90%), Sn grade tin concentrate≥45%( recovery rate≥70%) are obtained.
