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).

8 in. x 2 in. 1 lb. Lox 2 Flat Scavenger Head Yellow Zinc Coarse Thread (Approximately 127-Pieces) Driving wood-to-wood screws and deck screws can be a lot of work and a challenge especially when driving into harder materials. Anyone who has used wood screws has had experience with strip-outs, popped heads and screws that don't seat flush.

Cobbing, as used in this; paper, refers to coarse dry magnetics separation. It is applicable when, by its practice, plant cost can be reduced or the value of its products increased by the removal of a barren or lean reject or a high grade final product. This paper attempts to describe cobbing as it is now being practiced, and also the problems that are of concern to the operator and design ...

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 ...

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.

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.
