The beneficiation system of pyrite powder and beneficiation

the beneficiation system and beneficiation process of pyrite powder are equipped with a feeding car at the outlet end of the lower part of the upper hopper. The materials are crushed by the primary crusher and the secondary crusher, and then transported to the silo through the transfer station. The lower outlet of the silo is equipped with a feeder under the outlet, which is connected with the feed inlet of the ball mill. The materials ground by the ball mill pass through the primary magnetic separator, the secondary magnetic separator, the forge mill, the tertiary magnetic separator After magnetic separation by four-stage magnetic separator, five-stage magnetic separator and six-stage magnetic separator, the magnetic materials are precipitated in the sedimentation tank to obtain iron ore powder. After the separation of iron ore powder, the tail 1373 ore tank is connected with the sulfur powder sedimentation tank. Taking advantage of the characteristics of high sulfur powder ratio, the sulfur powder is obtained after sedimentation, and then the sulfur powder is transported to the flotation device for flotation. After flotation, the fine sulfur powder is obtained by sedimentation in the sedimentation tank again; The yield of iron ore powder screened by the invention can reach more than 99%, the grade of iron can reach more than 68%, and the grade of sulfur powder can reach more than 45%. It has the advantages of low cost, high profit and avoiding resource waste
