To increase the efficiencies of crushing and grinding, new crushers and mills should be developed. In this direction, highpressure grinding roller (HPGR) mills, developed in the 1980s (, Schönert 1979, 1988), represent a relatively new technique in mineral processing. The HPGR mills yield higher energy efficiency than ball mills, probably ...

1. Introduction. Pellet feed material generally results from fine grinding to achieve a liberation size roughly between 20 μm and 150 μm. Following this, beneficiation is applied to generate concentrate grades of 6569% Fe, by gravity separation, magnetic separation or flotation, or combinations thereof.
The first step of physical beneficiation is crushing and grinding the iron ore to its liberation size, the maximum size where individual particles of gangue are separated from the iron minerals. A flow sheet of a typical iron ore crushing and grinding circuit is shown in Figure (based on Ref. [4]).This type of flow sheet is usually followed when the crude ore contains below 30% iron.
grinding circuits, ball and rod mill circuits, and crushing circuits are also available for testing and design purposes. Inplant audits allow modeling and simulation of existing plants to assist in optimization. Rotary scrubbers and attrition scrubbers are available to test lateritic iron ores. physical mineral separaTion / BeneficiaTion
