Two alternative processing systems for pulverized minerals are summarized in Figure 11-19.2-2. In dry processing systems, the mineral aggregate material from conventional crushing and screening operations is subject to coarse and fine grinding primarily in roller mills and/or ball mills to reduce the material to the necessary product size range.

In the beneficiation operation, the crushing and grinding operation is to separate the useful components and impurities that are closely combined and symbiotic in various useful minerals, that is, "dissociation". After the materials are dissociated, the impurities can be removed by the method of beneficiation and a pure concentrate can be obtained.

Most mineral processing operations are conducted with water as the medium; this is called wet processing against dry processing. Crushing, grinding, milling, and vibration (feeding) are examples of comminution processes. Sizing / Separation Sizing is the general term for separating minerals according to their size.

High Impact Grinding. Mineral processing typically involves the crushing and grinding of hard rock ore. Crushed ore is introduced to semi-autogenous grinding (SAG) mills, also known as primary mills, where grinding media is released like hammers to assist in the ore cracking / grinding process. The mix of media and ore rises and falls in the ...

Crushing and grinding is the most costly step in mineral processing because the power needed to liberate the minerals is very high. In this sense, grinding is commonly said to be the key to good mineral treatment and the major consumer of energy, accounting for up to 50% of a concentrator's energy consumption ( Table 6.3 ).
