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-

If the gangue mineral in an iron ore is predominantly quartz, reverse flotation is usually used in the cleaning stage to improve the concentrate grade. Figure 9.13 presents a typical flow sheet for processing an oxidized iron ore containing about 30% Fe using a combination of SLon magnetite separators and reverse flotation. The ore is mainly ...

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.
