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 (ore concentrate) and a waste stream (tailings). There are many different types of beneficiation, with each step furthering the concentration of the original ore.

Beneficiation - an overview | ScienceDirect Topics

Beneficiation is followed by processing activities such as smelting and refining. 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.
