A process for upgrading lowgrade magnetitecontaining iron ore with minimum fine grinding the dry ore is first comminuted to between about threefourths inch and mesh particle size and magnetically separated the dry tailing is discarded and the concentrate is ground to between about and mesh and again subjected to dry magnetic separation.May 30, 2015 and magnetite. Quantitatively, higher volumetric fractions in quartz and lower volumetric fractions in iron oxides hydroxides and accessory minerals were verified on the flotation and coarse magnetic separation tailing samples, while fine magnetic separation tailings samples presented higher proportions in iron.

Inventory Of Magnetite Separation Processes Xinhai

Because of the strong magnetism of magnetite, the extraction of iron from magnetite is weak magnetic separation technology. The magnetite iron ore processing maninly includes It is suitable for the extraction of iron from simple single magnetite. It can be divided into successive-grinding weak magnetic separation process and stage-grinding.Announced in 1700 the application of magnetic separation to treat cassiterite con-taminated with iron, which could not be separated by water washing. The treatment was carried out by a hand magnet. In 1792 Fuller applied for a patent for the separation of iron ore using a magnet. In 1854 Palmer proposed a magnetic separator with magnet.
