Hindered-bed separators can concentrate particles based on size, density and shape. With feed stocks having a relatively tight size distribution, separations based on density and shape can be successfully achieved. Common applications include removing rock (SG 2.65) from coal (SG 1.35), upgrading iron ore, and the removal of silica from heavy-

wet versions to the iron ore industry. has (in close co-operation with the iron ore mining Industry) developed and designed the low intensity magnetic separators to meet the highest demands for capacity, metallurgical performance and mechanical availability. Models and sizes The range of wet magnetic separators is com-
Drum magnet separators differ from pulley magnet separators in that they are only magnetically active on a portion of the outer shell circumference (typically around 200°). The magnetically active section of the shell is facing the material and attracts the ferrous, while the non-magnetic section discharges the recovered ferrous from the drum.
Density-based separation of coarse iron ore was achieved using a gravity separator. • Coarse iron ore were efficiently upgraded by discharging waste gangue. ... Therefore, the high-density coarse iron ore particles were more likely to float on the bed surface and reduce the concentrate. Moreover, the movement distance of the coarse iron ore ...
A Floatex density separator was used to reduce the silica and alumina contents of a low-grade iron ore plant reject sample from the Pilbara region in Western Australia to produce a high …
MIMS SGM are wet magnetic separators used in industrial recycling aimed at concentrating the low magnetic charge ferrous metal found in the iron ore and industrial residues processing material. Medium Intensity Magnetic Separator (MIMS) are magnetic drums which are installed in rows of permanent magnets that generate a very high and homogeneous ...
