Abstract

The invention belongs to the technical field of mineral processing, and in particular relates to a suspension for dense medium mineral processing and its preparation method and application. The suspension for dense medium mineral processing includes ferrosilicon powder and magnetic powder. By limiting the ratio of ferrosilicon powder and magnetic powder, the density and stability of the dense medium mineral processing suspension are controlled, and it is not easy to occur during placement and use. Settling, the system is stable; when the suspension is used for mineral processing, the cost of separation and suspension can be reduced under the premise of ensuring the separation accuracy; the ferrosilicon powder and magnet powder in the suspension can also be recycled, purified and recycled. By controlling the particle size of ferrosilicon powder and magnet powder, it can be suspended. If the particle size is too coarse or too fine, it will affect the dynamic rheology and dynamic stability of the suspension, and then affect the separation accuracy and medium loss of ore.

Description

technical field [0001] The invention belongs to the technical field of mineral processing, and in particular relates to a suspension for dense medium mineral processing and its preparation method and application. Background technique [0002] Due to the rapid economic development, the consumption of mineral resources has increased sharply, and the lean ore, associated ore, and miscellaneous ore resources that were difficult to use before have also begun to be developed and utilized. The primary problem for various mining companies to develop and utilize lean ore, associated ore, and miscellaneous ore resources is processing cost. Coarse-grained and fine-grained disseminated ores undergo coarse, medium and fine crushing, a large number of gangues can be dissociated, and the useful minerals appear as monomers and conjoined bodies. At this time, dense medium beneficiation can be added in different crushing stages to obtain block fines. Dense media beneficiation has low product...
