Description
Technical field
The present invention relates to a kind of sorting mineral systems more particularly to a kind of differentiation of flotation device to configure system.
Background technology
In sorting mineral, flotation is most widely used beneficiation method.Flotation has wide range of applications, in the world using floating
The ore that method is processed is selected to account for about 60%~70% or more of all selected amounts, optional mineral have over one hundred kind.Flotation production target
Easily by multifactor interference, such as：The performance of floatation equipment, the type of medicament and dosage, the degree of dissociation of valuable mineral, valuable mineral
The size of granularity, number of sludge content etc..In most of flotation mills, floatation equipment configuration is single, and same flotation operation is general
The flotation device for being all made of standard configuration is produced, and is only capable of meeting the production requirement in general ore dressing plant.It is useful in flotation is to mine
When the fluctuation of mineral grade is larger, same operation configuration flow cannot take into account recycling coarse fraction valuable mineral and the useful mine of fine fraction
Object, general production target is poor, cannot be satisfying.
In the prior art, valuable mineral is thick, thin when being unevenly distributed in flotation is to mine, generally frequently with thick, subfractionation is floating
Choosing or direct flotation, and the floatation equipment configuration in ore dressing plant is single, same flotation operation generally uses the flotation of standard configuration
Machine is produced.
When the flotation in order to improve coarse fraction valuable mineral, the following measure of generally use：
Collecting to coarse fraction grade is strengthened using strength collecting agent, increases the adhesive strength of valuable mineral and bubble, is reduced
Fall off probability.
Improve the floating of coarse grain mineral by increasing ore pulp mass concentration to improve the technological means of ore pulp buoyancy.
Using shallow slot flotation device, shorten the floating distance of mineral laden bubble, reduces coarse grain ore particle from falling off on mineral laden bubble.
The appropriate velocity of discharge for increasing foam, the mineral that prevent from having floated drop in ore pulp again because that cannot be discharged in time
Chance.
When in order to improve fine fraction valuable mineral recovering effect, the following measure of generally use：
Using multistage grinding, the generation of sludge is reduced and prevented, recovering effect is influenced.
Sludge scattered inhibitor is added into ore pulp, cleans mineral surfaces, reduces sludge and the mud cover of mineral is polluted.
Collecting agent is added using segmentation, improves selectivity of the collecting agent to valuable mineral.
Sludge is removed before flotation in advance, reduces interference of the sludge to flotation.
The shortcomings that above-mentioned prior art：
The configuration of existing same flotation operation flotation device can only be directed to coarse fraction valuable mineral or fine fraction valuable mineral returns
A kind of situation when receiving difficult in the two is solved, and cannot solve flotation to for example both above-mentioned situation of valuable mineral in mine simultaneously
In the presence of or both situation be alternately present when valuable mineral high efficiente callback technical bottleneck, can not solve in the same operation of flotation thick
Grade valuable mineral and fine fraction valuable mineral take into account the problem of recycling simultaneously so that the valuable mineral rate of recovery is relatively low, causes to provide
Source wastes or even environmental pollution, while it is all to be easy to cause that production is difficult to stablize, dosing is difficult to grasp in these cases etc.
Mostly insoluble problem.
Invention content
The object of the present invention is to provide a kind of differentiation of flotation device to configure system.
The purpose of the present invention is what is be achieved through the following technical solutions：
The differentiation of the flotation device of the present invention configures system, and in same flotation operation system, while it is floating to configure high turbulent flow
It includes roughing operation to select machine and low overflow weir shallow slot flotation device, the flotation operation system, and the roughing operation is connected with more
A selected operation and multiple scan operation.
As seen from the above technical solution provided by the invention, the differentiation of flotation device provided in an embodiment of the present invention is matched
System is set, the floatation kinetics environment for being suitble to different minerals is built respectively by differentiation configuration, solves two kinds in the prior art
Situation exists simultaneously or both when being alternately present, and mineral take into account the technical bottleneck problem of recycling, and solve production be difficult to stablize,
Dosing is difficult to control the problems such as low with the valuable mineral rate of recovery.
