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.
Oct 01, 2014 Comminution will require rock size reduction by crushing and grinding. Size classification will require screening, de-sliming and cycloning. In the case of a lower-grade iron ore, the beneficiation process includes activities such as crushing, milling, gravity or heavy media separation, screening and silica froth flotation.
The goal of beneficiation is to eliminate inefficiency and waste by ensuring that as much recoverable material as possible is extracted from ore. A number of techniques can be used for this, often starting with grinding the ore into particles. Once ground, the particles can be sifted and sorted to extract usable material and set waste aside.
