cobbing magnetic

Northshore Mining Company

is directed to dry cobbing, which is a dry magnetic separation process used to reject the portion of the ore that does not contain sufficient magnetic iron. The ore not rejected during dry cobbing is sent to a series of wet grinding and concentrating processes to separate, concentrate, and recover the iron from the incoming ore.

Magnetic Separation

The WHIMS range includes 4, 16, 24 and 48 pole machines with either 68 or 120 millimetre separation matrix widths. WHIMS separators are suitable for applications requiring higher magnetic field gradients to remove weakly magnetic particles from non-magnetic concentrates. Nominal capacities range from 6 to 150 tonnes per hour.

Dry Magnetic Cobbing Separation

 · When fine-grained magnetite is the only mineral of value and there is a minimum of dilution rock and barren material in the ore, elimination of cobbing in the crushing plant in favor of wet rougher magnetic separation in the grinding circuits should be considered. Sampling of a cobbing plant is always difficult when treating coarse material.

Drum Separator

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.
