Developed a kind of centrifugal floatation sorting machine, it combines centrifugal method and method for floating, to reclaim relatively large valuable mineral.Though this flotation device provides a kind of ten minutes useful device and method, but still expectation provides a kind of faster, more economical and regeneration to reclaim the improved centrifugal floatation sorting machine and the method for more valuable mineral, wish that they if not fully, at least also will overcome most of above-mentioned problem of mentioning.
A kind of improved efficient centrifugal flotation device that is provided and method can more easily reclaim more valuable mineral pellet, the fiber that contains as gold, platinum, silver, nickel, sulfide and other metal, ore, trace element, ore in sand form, paper, fiber and other, be vegetable matter, and oil.Obviously, centrifugal floatation sorting machine of the present invention and method are effective, economical, efficiently, and the method and apparatus that can be recovered in the prior art in the mine tailing can not recoverable very tiny valuable mineral.
This user's of helping centrifugal floatation sorting machine utilizes centrifugal force and flotation to make up and promptly reclaims molecule, obviously, this flotation device and method use easily, reliable, attractive, and can provide than the conventional separation and the higher output and the rate of recovery of method.
In centrifugal method for floating of the present invention, by for example air ejector, an aerator or preferably bubble is sprayed in the fine particle ore pulp, so that ore pulp is carried out bubbling and inflation by a bubbler.Ore pulp and bubble are guided downward, and preferably both are guided downward together enters a centrifugal separating device through a downward feeder, and this device is best to be made of a centrifugal flotation cell.Ore pulp and bubble are rotated and centrifugal treating, ore pulp is divided into one by not floating waste material materials flow that slag charge constitutes and the foam that is enriched with particle that contains bubble, this bubble is taken and is contained the valuable granule materials that major part will be recovered, and the refuse materials flow is discharged and removes.The foam that is enriched with particle is removed and is reclaimed by froth flotation.In this best approach, be raised to the surface at the foam that contains particle, and radially outwards cross a downflow weir sidewards and enter before a letdown tank and the foam hurley log washer, foam is radially inwardly guided.
Centrifugal floatation sorting machine of the present invention has a fixed downward feeder and a sedimentator with rotating flotation cell, preferably has a rotating cylinder.One Power Available Shaft passes this downward feeder.This manipulable mode is connected the bottom of sedimentator, and by a motor-driven, thereby sedimentator is rotated.In one embodiment, sedimentator has the flat of a band toroidal sidewall.In another embodiment, sedimentator has the bowl-shaped body of a band concave bottom and curved wall.
One flotation chamber is arranged between the sidewall of downward feeder and sedimentator.This flotation chamber can have one or more vertical walls, and this cornice has a weir that extends to sedimentator top certain altitude.One letdown tank can be connected with the weir above sedimentator, so that the discharging foam.
Centrifugal floatation sorting machine also has a housing with some vertical shell walls, and these shell walls are provided with around the outside in sedimentator, downward feeder and flotation chamber.This housing has an inclined bottom and an outlet, and they are placed on the plane below the sedimentator, with convenient discharging of not floating the slag charge waste stream.Slag charge is downward through before slag charge between sedimentator and the shell wall holds passage at it, preferably upwards by a circular passage that is arranged between flotation chamber and the sedimentator.
One spoiler can extend between flotation chamber and shell wall, and the flotation chamber is connected on the shell wall between sedimentator and the letdown tank.
In an illustrated embodiment, an ore pulp feeding pipe is communicated with downward feeder, and ore pulp is delivered in the downward feeder, a bubbler then is arranged in the ore pulp feeding pipe, in order to bubble is injected ore pulp.Before ore pulp was injected into bubble, ore pulp can upwards flow in the equipment outside.Ore pulp and bubble flow to downwards before the sedimentator, can also flow jointly in a horizontal direction.In some cases, can wish ore pulp and bubble to be sent into downward feeder or centrifuge with independent pipeline.
