comminution in ore beneficiation

Ore Beneficiation - an overview ScienceDirect Topics

Low-grade hematite ores need to be upgraded to achieve the required iron content, which involves more complicated ore beneficiation processes. The level of comminution required for the low-grade hematite ore is similar to high-grade ores to deliver the same products, lumps and fines.

What Is Beneficiation In Mineral Processing? - Minerallurgy

Generally, comminution is the first step in mineral beneficiation because it achieves several things, not only the particle size reduced, but you create new surfaces, and you liberate minerals. Crushing and grinding also have to be followed by a process called sizing. You cannot undergo comminution, crush, grind, or leave it uncontrolled.

Comminution - Wikipedia

Comminution is the reduction of solid materials from one average particle size to a smaller average particle size, by crushing, grinding, cutting, vibrating, or other processes. In geology, it occurs naturally during faulting in the upper part of the Earth's crust. In industry, it is an important unit operation in mineral processing, ceramics, electronics, and other fields, accomplished with ...
