Description
Technical field
The present invention relates to a kind of oxidized coal slime sorting technology based on nano bubble processing ore pulp, specifically providing one kind can
The method for significantly improving the oxidized coal slime rate of recovery.
Background technology
Due to China as the raising of Mechanized Coal Mining Operation in China degree, coal slime ratio sharply increase, the task of slime separation
Constantly increase, the characteristics of " thin, miscellaneous, poor, difficult " is presented the characteristics of coal slime.Before at the same time, there is coal mining in the whole country,
The phenomenon being oxidized in exploitation and after exploitation, once being oxidized, its floatability will fall rapidly upon coal, after coal is oxidized, its
Hydrophilic radical (- the OH ,-COOH ,-CHO) content on surface increases sharply, hydrophobic group (alkyl side chain etc.) content drastically under
Drop, so as to cause the floatability of coal persistently to reduce.Meanwhile coal, after peroxidating, its surface becomes loose, porosity increase is more
The coal grain in hole is easy to be filled by water in water, forms the hydration shell of thickness, so as to further result in the reduction of the hydrophobicity of coal.
In the floatation process of routine, the surfactant of charged particle and its oppositely charged in ore pulp draws in electrostatic
Had an effect in the presence of power, SURFACTANT ADSORPTION or be covered in coal particles surface, improve its hydrophobicity, so with gas
Bubble, which collides to be adhered on bubble, eventually becomes foam cleaned coal, but because the thick hydration shell of oxidized coal, medicament are difficult in its table
Face covers and caused more difficult floating.Meanwhile oxidized coal coal slime due to grain graininess it is smaller, its momentum is smaller, is touched with bubble
The probability hit is relatively low, and cleaned coal particle is difficult to be collided with bubble, and being not susceptible to collision with bubble causes it to be more difficult to pass through flotation
Mode be recycled utilization；And the microfine clay mineral of high ash is then entered by way of thin mud cover lid or current entrainment
In floatation clean coal product, floatation clean coal is polluted, is degrading flotation effect, therefore under the flotation practice of routine, oxidized coal coal
The sorting upgrading of mud is difficult to ensure that the rate of recovery and product quality.
For the problem of oxidized coal coal slime flotation, many experts and scholars both domestic and external have done many beneficial explorations, such as make
Substitute common diesel oil, coal-grinding pretreatment, ultrasonic pretreatment, Microwave Pretreatment, pre- profit with the new medicament such as oxidated diesel oil
The means such as the control of wet time improve the flotation efficiency of oxidized coal, achieve certain effect, but do not solve oxygen fundamentally
The problem of flotation efficiency of change coal slime is low, and for the flotation of oxidized coal slime, conventional means, such as pre-processed by coal-grinding
Oxidized coal is exposed the method on fresh surface and do not adapt to the flotation of such coal slime.Therefore it is a kind of new to need exploitation badly
Sorting technology realizes the efficient separation recovery of oxidized coal slime to make up the deficiency of existing slime separation technical elements.
The probability of particle and bubble hit substantially reduces with the reduction of particle in floatation process, but with the reduction of bubble
Collision probability can but increase, and this shows that oxidized coal slime can be improved by using the bubble of reduced size in subsieve flotation
Flotation effect, the present invention proposes to float in ore pulp processing stage to oxidized coal surface and introduces the nanometer gas with positive electricity electric charge
Bubble, enhances the floatation process of oxidized coal, substantially increases its rate of recovery.
