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

Various alloys, like NdFeB (an alloy of neodymium, iron, and boron ), keep their domains aligned and are used to make permanent magnets. The strong magnetic field produced by a typical three-millimetre-thick magnet of this material is comparable to an electromagnet made of a copper loop carrying a current of several thousand amperes.

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).
