Abstract
The invention discloses a method for settling and separating mud with a high molecular organic dispersant and belongs to the technical field of mineral separation and purification. The method comprises the following steps: making clay to which the high molecular organic dispersant is added into mud; settling and separating to remove chippings; and carrying out ozone aeration on relatively pure mud at the top. The high molecular dispersant is oxidized through strong oxidizing aeration of ozone, so that stable balance of stable and suspended clay mud is broken and the clay mud can be naturally settled. Soil-water separation of mud is realized, and a clay mineral powder product is obtained.
Description
Technical field
The present invention relates to the method that sedimentation occurs fast for argillaceous mineral and macromolecule dispersing agent mud, be applicable to mineral purification technique field, be particularly related to a kind of for making to have added the settlement separate method of polymer organic dispersing agent mud, a kind of by add the strong oxidizers such as ozone in mud specifically, make because the stability that adds macromolecule dispersing agent to be the clay mud of stable suspersion state is destroyed, thereby realize the method that clay particle is separated from mud.
Background technology
Generally, even the clay mud gravitate fully suspending impact, at short notice will sedimentation, there is mud-water separation.In clay pit ore dressing field, when the purity of clay is not high, in order to remove impurity fragmental products wherein and to promote clay purity, often need in mud, add organic polymer dispersion agent to make suspension and the good mud of stability, can be in the good mud of stability by the settlement separate impurity fragmental products that makes, under action of gravity, be deposited to the bottom of container, realize the object of separating-purifying.But ensuing problem is conventionally all very thorny.Remove the mud (being usually located at the top of container) of impurity chip, needed dehydration to obtain Powdered clay product.But because the clay mud making by organic polymer dispersion agent is conventionally all highly stable, want from mud, to obtain clay powders more difficult.For clay muds such as large stretch of kaolin, montmorillonites, be generally by ultrafiltration or high speed centrifugation, the water in mud to be discharged, leave powder clay.But for the tiny powder clay of nano level, as polygorskite or attapulgite, because the particle diameter ratio the thinnest existing mesh screen of clay mineral is also thin, the method for ultrafiltration can cause loss, reduce the rate of recovery.
Summary of the invention
1, the technical problem that invention will solve
Main purpose of the present invention is for the problem in existing clay pit sedimentation purification, provide a kind of for making to have added the settlement separate method of polymer organic dispersing agent mud, strong oxidation and aeration by ozone makes macromolecule dispersing agent oxidized, thereby break the stable equilibrium of the clay mud of stable suspersion, make the clay mud can natural subsidence.Soil-water of realizing mud is separated.
2, technical scheme
Inventive principle
Ozone, O
3, be a kind of strong oxidizer, can be oxidized most organic compound.Organic dispersing agent, as sodium polyacrylate conventional in clay purification, polyoxyethylene glycol etc. are the chain polymer that molecular weight is huge, the frame shape structure that C-H molecule aggregation becomes is fully disperseed the clay particle in water, forms stable colloid.If adding ozone, O by the stable mud of macromolecule dispersing agent
3strong oxidation can make chain polymer " smash " to become CO
2and H
2o.In aqueous dispersion, by very fast unstability, there is dehydration and the sedimentation of colloid in the clay particle that loses macromolecular scaffold.Isolate the object that sediment has just reached slurry dewatering.
Technology contents:
For making to have added a settlement separate method for polymer organic dispersing agent clay mud, the steps include:
(1) polymer organic dispersing agent is dissolved in the water, preparation is the mixing solutions of 0.2 ‰～0.5 ‰ polymer organic dispersing agents containing mass percent;
(2) in the mixing solutions of step (1) configuration, add the suspension that clay preparation mass percent is 1～15%,, after soaking, with pulping equipment, break into mud;
(3) this mud is placed in to settling leg precipitate and separate 2～24 hours, then removes the chip impurity of settling leg bottom;
(4) pass into ozone, to the remaining mud that is suspended in settling leg top after step (3) is processed, carry out ozonation aerated;
(5) standing after aeration, realize mud-water separation, remove upper strata clear water, obtain high concentration slurry, after doing, make clay breeze.
In described step 1, polymer organic dispersing agent is sodium polyacrylate, polyoxyethylene glycol or polyacrylamide.
The molecular weight 1000 to 1,000,000 of described sodium polyacrylate, polyoxyethylene glycol or polyacrylamide.
Clay described in step 2 is attapulgite clay, kaolin or montmorillonite.
Ozone dosage described in step 4, passes into ozone according to the mass ratio of ozone: dispersion agent=1:1～1:5.
In described step (2), after soaking, with pulping equipment, break into mud, comprise immersion, pair roller, smash slurry, stirring, ultrasonic, clarifixator, molecular mill, colloidal mill method and apparatus, bulk or Powdered clay are fully mixed with into mud with macromolecule dispersing agent.
3, beneficial effect
Innovative point of the present invention and feature are:
(1) of the present invention for smashing the ozone of macromolecule dispersing agent, final fragment residual after completing strong oxidation only has CO
2and H
2o, does not almost destroy the attribute of clay product, does not form new hazardous and noxious substances yet.This use to purification clay is extremely important.
(2) owing to adopting suspension pulping------ozonation aerated to the stable mud suspending---mud in suspension unstability precipitation of sedimentation fragmental products with the conventional clay ore deposit separated very close technique of purifying, original clay purifying technique is without huge transformation.
