The factors that affect the magnetic separation process. 1. Feeding size. The feed size is an important factor that affects the separation effect of the magnetic separator. For most ores, the size of the feed particle size means the degree of separation of ore monomers, that is, the degree of separation between magnetic ore particles and gangue ...

The trace impurities of a uranium ore concentrate (UOC) can be examined to determine mine source, methods of production, and quality. This study presents a method to determine the concentration of halides and main group elements, specifically P, S, Br and I, utilizing triple quadrupole inductively coupled plasma–mass spectrometry.

Magnetic separation has been used since 1955 for processing a variety of minerals from iron ore in steel production to the desulphurisation of coal. The accumulation of such fines and slimes during mining operations and the increasing global demand for quality products motivated the use of the semi-continuous pilot wet high intensity magnetic separator (WHIMS) introduced in 2008.

Magnetic Separation: Minerals can be separated on the basis of differences in magnetic susceptibility. Magnetic separation has been used in Canada to separate iron ore from waste minerals, to remove magnetite (iron oxide) and pyrrhotite (iron sulphide) from base metal ores prior to flotation, and to recover magnetite from copper concentrates.

Magnetic separation is most commonly used in the mining industry to separate "tramp ore," or unwanted waste metals, from the rest of the bulk material. Tramp ore typically consists of the man-made byproducts created by the mining process itself, such as wires from explosive charges, nuts and bolts, nails, broken pieces from hand tools such ...
