Vanadium titanomagnetite (VTM) is an important mineral for developing titanium resources, but the comprehensive recovery of ilmenite separation is extremely poor, resulting in the low-efficiency utilization of titanium resources. Here, the separation of ilmenite from VTM ore is studied by combining magnetic separation and flotation …

2.4. Beneficiation methods. Beneficiation is a process where ore is reduced in size and valuable minerals are separated from the gangue minerals. Separation of valuable minerals from gangue minerals can be efficiently achieved by taking advantage of the differences in physical, surface, and magnetic properties.
