What is mineral beneficiation? Mineral beneficiation is a process by which valuable constituents of an ore are concentrated by means of a physical separation process. As one of the initial steps of extractive metallurgy, the main purpose is to prepare the ore prior to downstream purification processes.

The commonly used beneficiation processes of scheelite include froth flotation, gravity separation, and gravity separation–froth flotation combined process. For finely disseminated scheelite ore, the froth flotation process is generally adopted. For coarse-grained scheelite ore, gravity separation can be adopted for pre-concentration.

Froth flotation, developed commercially in the 19th century, is the most widely used in these three kinds of beneficiation plants. Unlike magnetic separation, froth flotation enhances the difference in hydrophobicity between useful minerals and impurities by adding surfactants and wetting agents.

The beneficiation process begins with milling, which is followed by flotation for further beneficiation. At the first stage, extracted ores undergo the milling operation to produce uniformly sized particles for crushing, grinding, wet or dry concentration. The type of milling operable in a certain plant is chosen by capital investment and

The choice of the beneficiation treatment depends on the nature of the gangue present and its association with the ore structure. Several methods/techniques such as jigging, washing, magnetic separation, gravity separation, and flotation etc. are being used to enhance the iron percentage in the Iron ore and to reduce its gangue content.
