Description
Technical field
The invention belongs to mineral manufacture field, more particularly to a kind of method of slurry concentrating dehydration is suitable for each to mine
Class ore pulp carries out thickening.
Background technology
When underground mine carries out underground filling using tailing, since tailings concentration is very low（It is low less than 10%, it is high by only 30%
Left and right）, it is necessary to thickening is carried out to it, to reach concentration needed for underground filling, meanwhile, so that mine is realized quick return water profit
With.
Traditional filling process is that the tailing ore pulp of ore dressing plant output is raised using sand pump and sent to concentrator, is concentrated into underflow
Concentration 40% or so, then raised and given to Filling Station into sand warehouse with sand pump, sedimentation concentration, finally makes pulp density reach 65% or more again
When, then mixed with additives such as gelling agents, carry out underground filling；Concentrator is returned into sand warehouse overflow water.And in Filling Station into sand
During carrying out sedimentation concentration again in storehouse, easily there is Filling Station and run mixed phenomenon into sand warehouse overflow water, run and mix in overflow water
Subparticle can continuous cycle in the process always, and constantly deteriorate effect of settling, even if flocculant is used to strengthen sedimentation
Its influence can not be completely eliminated.
Invention content
Present invention aim to address the sedimentation deterioration problems that subparticle in slurry concentrating dehydration is brought.
To solve the above problems, present invention firstly provides a kind of slurry concentrating dewaterings, it is characterised in that comprising as follows
Step：
Step 1：Ore pulp is classified and is concentrated using cyclone first；
Step 2：It controls hydrocyclone sand concentration and is not less than 70%, yield is about 2/3, and hydrocyclone sand flows automatically to high concentration stirring
Bucket；
Step 3：Cyclone overflow flows automatically to concentrator and is concentrated, while adding flocculant, fine in rotational flow strengthening device overflow
Grade settles；
Step 4：55% or more thickener underflow concentration is controlled, thickener underflow is raised with sand pump and is sent to high concentration agitator, with
Hydrocyclone sand mixes, and obtains ore pulp of the concentration 65% or more.
The present invention also provides a kind of slurry concentrating dehydration devices, it is characterised in that including a cyclone, a concentrator, one is high
Concentration agitator, the cyclone are respectively connected to the concentrator and the high concentration agitator, and the cyclone is to ore pulp
Be classified and concentrated, hydrocyclone sand flows automatically to the high concentration agitator, cyclone overflow flow automatically to the concentrator into
Row concentration, thickener underflow is sent mixed to high concentration agitator with hydrocyclone sand after obtain ore pulp of the concentration 65% or more.
The present invention has used cyclone to be classified and concentrated, has not only realized first in slurry concentrating dehydration
Thickness grading, while also achieving the high concentration concentration of 2/3 mine amount.
The present invention concentrates fine-graded cyclone overflow using concentrator, and when concentration adds suitable flocculant -- and poly- third
Acrylamide, accelerated sedimentation, 55% or more control thickener underflow concentration.
The present invention implements the mixing of thick fine fraction concentration ore pulp in high concentration agitator, to obtain 65% or more concentration
Ore pulp to be filled, the addition filling gelling agent and after mixing well as required in high concentration agitator, to underground goaf reality
Filling is applied, filling process flow is simplified, eliminates micro-size fraction material（Thin mud）Vicious circle in technical process.
This invention removes Filling Stations into the overflow water return of sand warehouse, can thoroughly solve subparticle and deteriorate effect of settling
The problem of.
Thickening apparatus structure of the present invention is simple to operation, can be widely applied to all kinds of slurry concentrating dehydrations in mine, especially
It is suitable for mine tailing filling system, to the other industry or field that need to carry out thickening also have certain popularization and
Reference has good popularizing application prospect.

Concentration agitator 7, wherein cyclone 5 are respectively connected to concentrator 6 and high concentration agitator 7.
The tailing ore pulp of ore dressing plant output by broken, ore grinding and after sorting, is pooled in tailings pump pond 1, uses CHARACTERISTICS OF TAILINGS SAND
Pump 2 is raised to send to cyclone and be pumped in pond 3 to mine；Tailing ore pulp is raised to mine pump 4 with cyclone and is sent to cyclone 5, carries out control point
Grade and concentration.
Control 5 sand setting amount of cyclone accounts for about the 2/3 of tailing total amount, and controls sand setting concentration and be not less than 70%.Account for tailing total amount
About 2/3 hydrocyclone sand flows automatically to high concentration agitator 7, account for tailing total amount about 1/3 cyclone overflow then flow automatically to it is dense
Machine 6 is concentrated.Suitable flocculant is added in concentrator 6 -- polyacrylamide, to accelerate microfine in cyclone overflow
Grade sedimentation.55% or more thickener underflow concentration is controlled, thickener underflow is raised with sand pump and is sent to high concentration agitator 7.
