Abstract
The present invention is a kind of new technology in the sorting mineral.Can be used for branch, to elect granularity as meticulous and produce cohesion, be difficult for the charged nonmetallic minerals such as talcum powder of selectivity because of electrical property difference is little.
Its technical process is for placing the talcum powder material of drying one by fluidization bed that sealed gas chamber, ionising electrode and mechanical vibration source constituted, through vibration, fluidization, charged after, mineral grain is collected electrode and attracts, and the realization valuable mineral separates with gangue mineral.
This technology is compared with traditional method for separating, have power consumption less, advantages such as device structure is simple, cost is low, non-environmental-pollution.This technology also can solve the sorting problem of other fine grain grade non-metal mineral simultaneously.
Description
This technology is used to solve nonmetallic mineral such as talcum powder and produces the problem that is difficult to sort that cohesion is caused because of granularity is meticulous.
Along with the rapid minimizing of high grade ore reserve, the processing again of the fine fraction mine tailing that people's pay attention to day by day is discarded in the past and the exploitation utilization of fine fraction poor value.Adopt traditional floatation and common dry type ore sorting method can't handle this class ore.The cohesion of adopting high strength ionic polarizing electrode in this process and powder fluidization technology then can avoid mineral grain, it is charged to make the little nonmetal ore particle of electrical property difference reach best selective, thereby realizes that the fine fraction talcum powder effectively separates with other gangue minerals.
At present, external talcum powder mineral electrostatic separation adopts " pulley type " electrostatic separator to carry out usually, Norway's Bergen talcum of being introduced as " Fraas F; 1962; Electrostatic Separation of granular materials U.S Bureau of Mines Bulletin 603 " separates with magnesite, use be exactly this electrostatic separator.But the mineral monomer partition size in this ore deposit is more than the 0.5mm, so separating effect is obvious.Then can't sorting for the breeze below the 0.074mm.
The present invention's " fluidization electrostatic separation talcum powder technology " has solved nonmetallic minerals such as talcum powder and has condensed the problem that is difficult to sort that is caused because of granularity is meticulous.Its device is made up of as shown air chamber 1, ionising electrode 2, mechanical vibration source 3 and passive electrode 4.Technical process be with granularity be below the 0.074mm, water content places the fluidization bed less than 1% talcum powder material, and feeds low speed flow to air chamber, produces a vibration frequency and the vibration force of amplitude through selecting by mechanical vibration source; Feed 16.6～2.5l/min, 1～1.5Kg/cm
2Quantitative level pressure air; On ionising electrode, be added with 2.5～80,000 volts high direct voltage static.The mineral grain that is in boiling in the fluidize bed, is captured by the outer collecting plate of bed because the effect of electric field force sorts out from fluidize bed by after charged, reaches sorting purposes.
This technology is compared with traditional floatation, have power consumption less, advantages such as device structure is simple, cost is low, non-environmental-pollution, can finish the ore-dressing practice that common dry type ore sorting method can't be finished.Simultaneously, this technology also can solve the sorting problem of other fine grain grade non-metal minerals.
