Dry low-intensity magnetic separators are more commonly used for tramp iron removal (Elder and Sherrell, 2011) and coarse cobbing of magnetite ores (Aubrey, 1958, Connelly and Yan, 2009). They are generally inefficient for processing low-grade fine-grained magnetite ores (Xiong et al., 2015, Elder and Sherrell, 2011).

Two types of separators are used, dry and wet. Dry equipment is used more for coarse, strongly magnetic material and to protect processing equipment by the removal of tramp iron.

Dry low-intensity magnetic separation is confined mainly to the concentration of coarse sands which are strongly magnetic, a process known as "cobbing," and is often carried out using drum separators. For particles below 5 mm, dry separation tends to be replaced by wet methods, which produce less dust loss and usually yield a cleaner product.

This tank design is particulary suitable for cobbing and roughing of fine to coarse particles up to 3-8 mm (4 mesh) at medium to high densities (30 to 50% solids).. It is excellent for capacity and recovery, but should not be used as a single unit when highest concentrate grade is required.

In some situations, coarse cobbing by low-intensity and high-intensity magnetic separators are preferable. Since coarse particle size processing do not generally present very big processing challenges, such methods will not be further treated in this paper, except when preconcentration is a crucial part of advanced processing of the most ...
