15.12.2021At present, this issue cannot be addressed using traditional mineral processing technology. Herein, a strategy of metallurgy-beneficiation combination to decrease the TiO 2 grade in TC before smelting was proposed. Roasting TC with calcium carbonate (CaCO 3) together with magnetic separation proved to be a viable strategy.

Mineral processing can involve four general types of unit operation: comminution – particle size reduction; The force experienced in the magnetic field is given by the equation f=m/k.H.dh/dx. with k=magnetic susceptibility, H-magnetic field strength, and dh/dx being the magnetic field gradient. As seen in this equation, the separation can be driven in

Because iron is a metal and conducts electricity (even when molten), its motion generates a magnetic field. Earth's magnetic field is defined by the North and South Poles that align generally with the axis of rotation (Figure 9.13).
