Beneficiation - Wikipedia

In the mining industry or extractive metallurgy, beneficiation is any process that improves (benefits) the economic value of the ore by removing the gangue minerals, which results in a higher grade product (concentrate) and a waste stream ().Examples of beneficiation processes include froth flotation and gravity separation.. Other economic uses of the term are in use.

Separation Process and Method-Ore Beneficiation-

Separation is the main step of ore concentration. Metal recovery and productivity largely depend on the separation process and methods. Based on the physical and stone properties of ore like its stone size, shape, color, density, friction coefficient, magnetism, moisture and electric property, several process and methods are available.

Ilmenite Beneficiation by Roasting and Magnetic Separation ...

A new crude ilmenite beneficiation process was recently proposed that allowed for the preparation of a smelter grade ilmenite from ilmenite with elevated chromium content. Magnetising roasting was not utilised in the process. As part of this circuit an ilmenite low susceptible reject stream was produced that had a low magnetic susceptibility.
