The run-of-mine extracted from the ground requires further processing in order to make a marketable product. This preparation is called mineral processing. Thus, ores must go through a number of different operations to obtain the final products: comminution or size reduction, size separation, concentration or beneficiation, and dewatering.

Magnetic separators can be found in most mineral processing operations, especially those processing non-metallic minerals and magnetic ores. This article investigates the use of high intensity magnetic separators and magnetic separation equipment in the minerals sector with a focus on processing dry materials (in the -15mm, +45 micron size range).

Historically, mineral liberation has been used as a proxy for the “processability” of a particular mineral, since the many properties of minerals that could allow for concentration and processing could not be directly measured from auto-SEM instrumentation. Thus, the poor liberation of a mineral of interest in

Mineral liberation is essential for the mineral processing engineer, in that high grade mineral concentrates cannot be made without sufficient amounts of REE mineral liberation. This mineral liberation is produced during size reduction procedures (such as grinding) where finer grinding usually means increased liberation.
