A process for upgrading low-grade magnetite-containing iron ore with minimum fine grinding. The dry ore is first comminuted to between about three-fourths inch and 10 mesh particle size and magnetically separated. The dry tailing is discarded and the concentrate is ground to between about 20 and 100 mesh and again subjected to dry magnetic separation.

Basically Magnetism is used for five distinct type of. separation : 1.For the removal of iron in coarse and. intermediate- crushing circuits, as a. protection to the crushing machine. 2.For the concentration of iron ore other than. magnetite, after preliminary conversion of. iron minerals to artificial magnetite by. suitable Roasting.

Dec 17, 2020· First,Strong magnetic iron ore . 1.Single magnetite . The composition of iron ore of a single magnetite type is simple, and the proportion of iron minerals is very large. Gangue minerals are mostly quartz and silicate minerals. According to production practice research, weak magnetic separation methods are often used to separate them.

Magnetic separation is the process of separating components of mixtures by using magnets to attract magnetic ... The first pair of balls was weakly magnetized and served to draw off any iron ore present. ... (or magnetite) which can build up. The magnetic filter attracts all these bits of debris with a strong magnet as the water flows around it ...

Magnetic Separation is one of the physical concentration processes that utilizes the differences in magnetic properties of various minerals present in the ore body. The magnetic fraction may be valuable or gangue depending upon its end use in a particular process and so also the non-magnetic fraction, e.g., separation of magnetite (magnetic)
