Magnetic separation is widely used in the processing of titanium minerals. The expected mineral recoveries are assessed by performing laboratory magnetic separations of representative samples to determine the distri-bution of magnetic components. This is an inherently slow process performed on relatively small samples.

The purpose of strong magnetic separation is to discharge qualified tailings, increase the selected grade of titanium flotation, and reduce the amount of titanium flotation. The high-gradient magnetic separator can effectively recover the fine-grained ilmenite in the ore, and can throw away some of the fine mud in the ore, thereby achieving the ...
