Simple magnetic separation for a certain magnetite mine with ultrafine disseminated lean ores has resulted in low performance, as the fine sizes and aggregation of ground mineral particles have caused inefficient recovery of the ultrafine minerals. In this study, we attempt to increase the apparent sizes of target mineral particles, and improve the separation indices, by using a multi-stage ...

Separation of Solids and Fluids by Magnetic Flocculation

2019-5-21  Separation of Solids and Fluids by Magnetic Flocculation. Flocculation, the process of coagulation or coalescence of finely divided particles, is commonly used in separating fine solids from fluids. Forces disposing of the particles to flocculate include: ionic forces of attraction, secondary entropic forces, and magnetism.

2012-1-20  Flocculation, or agglomeration, of the particles can occur if they are small and highly susceptible and if the field is intense. This has great importance as these magnetic "flocs" can entrain gangue and can bridge the gaps between magnet poles, reducing the efficienilly of separation. Flocculation is especially serious with dry separating
