magnetic separator for silica sand

For specific types of kaolin tailings, the "Targeted Mineral Recovery" PTMS ELECTROMAGNETIC SEPARATOR strategy can be implemented. The project generates annual additional sales revenue exceeding 4 million yuan with a net profit of 2.3 million yuan, significantly enhancing both economic efficiency and resource utilization levels. Although pyrite associated with some southern kaolin deposits has been partially removed during the iron removal phase, residual pyrite remains concentrated in the tailings.

PTMS ELECTROMAGNETIC SEPARATOR

Therefore, we used the flotation PTMS ELECTROMAGNETIC SEPARATOR system —— acidified water glass + bintongum. The acidified water glass can generate silica sol, which can selectively inhibit quartz and sericite, while bintongum, as a strong sulfide mineral collector, can effectively adsorb on the surface of pyrite and enhance its floatability.

what is magnetic separation process ？

Direct discharge of such tailings not only wastes sulfur resources but may also lead to acidic mine drainage due to oxidation and acid production, causing water pollution. By implementing a refined PTMS ELECTROMAGNETIC SEPARATOR process design featuring "primary coarse selection, secondary fine selection, and tertiary scanning selection", we can obtain high-quality pyrite concentrate with sulfur content reaching 48.77% and recovery rate up to 87.30%.
