magnetic field strength can be divided into: (1) Dry electromagnetic magnetic separator, e.g., Induction roller magnetic separator, Lift roller magnetic separator, and Cross belt magnetic separator; (2) Dry permanent magnet magnetic separator. e.g., Rare earth roller magnetic separator and Rare earth drum magnetic separator

of a magnetic separator to lift a particular mineral is dependent not only on the value of the field intensity, but also on the field gradient, which is the rate at which the field intensity increases towards the magnet surface [6]. Production of a high field gradient as well as high intensity is therefore an important aspect of separator design.

Reduction roasting followed by magnetic separation is a promising method to recover the iron values from low-grade iron ores. The process involves the reduction of the goethite and hematite phases to magnetite, which can subsequently be recovered using a low-intensity magnetic separation unit.

tion with a permanent magnet. Figure 10 shows the relationship between the Gauss values of a permanent magnet and the AT values of Coto dry-reed switches in the Philips Standard Coil. It enables the customer to determine which reed switch AT range can be used in combination with a specific permanent magnet.

that along with manganese the cobalt value gets enriched (~Co: 0.38%) more than four times in comparison to the feed. Some other traces like Ni, Cu, Zn, Ga, Li etc. also get enriched in the magnetic product. Thus, through simple dry magnetic separation a low-valued material cannot

The process of magnetic separation is based on the differences among magnetic susceptibilities of various mineral species. Performed either wet or dry, the separation has application in both the recovery and concentration of value minerals, and in removing deleterious mineral constituents from a product stream.
