Abstract
The invention relates to an efficient floatation reagent for coal slime. The reagent comprises, by weight, 70-90 parts of hydrocarbon oil, 15-30 parts of alcohol oil, 0.5-1.5 parts of catalysts and 0.5-1 part of regulators, and the reagent can be obtained by mixing the components and stirring the mixture for one hour at normal temperature. The reagent has the advantages that smell is light, irritation is avoided, foamability is high, selectivity is high, consumption is low, foam is rich and even, foaming effect is good, hydrophobicity of coal particles can be improved to the maximum, the difference between hydrophobicity of particle surfaces and hydrophobicity of impurity surfaces can be increased, clean coal yield can be increased by 3-5%, the size and motion state of bubbles in coal slurry can be changed, power consumption for air agitation of ore pulp can be reduced, a foam layer required by floatation can be formed on the surface of ore pulp, a product is stable in bubble densification, high in selectivity and high in reaction speed, and influence of temperature and PH value is avoided.
Description
Technical field
The present invention relates to Coal dressing technology industry, especially relate to a kind of coal slime the most efficient flotation reagents.
Background technology
Coal slime flotation is the difference utilizing coal and spoil Surface Physical Chemistry character, and can cross add specific floating agent method to expand the difference showing machine wetability between coal and spoil, thus realize a kind of slime separation technology that coal is separated with spoil.Why flotation can be widely used in slime separation, and important reason is that it controls floatation process neatly by floating agent, and effectively realizes coal according to the requirement of people and be separated with spoil, makes coal resources obtain comprehensive high-efficiency and utilizes.Floating agent can improve the character of gas in floatation system, liquid, gas three-phase, the Air Bubble Size of generation, quantity, life-span, liter is made to float speed etc. and meet flotation requirement, the effect of the surface nature of mineral, mineral and other materials and the character of ore pulp can also be adjusted, change can not float mineral into floating, enable floating mineral are better floating, and improving the selective of flotation and flotation speed, the quality of flotation effect, floating agent is important factor.At present, its consumption of the floating agent used in coal industry is high, and clean coal recovery is low, and smell weight is selective poor, and coal particle hydrophobicity is low.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of low consumption amount, clean coal recovery is high, smell is light, non-stimulated, foaming characteristic is strong, selective good, enter to wash that speed is fast, the uniform coal slime the most efficient flotation reagents of foaming abundancy.
The present invention solves the technical scheme that its technical problem takes: a kind of coal slime the most efficient flotation reagents, and it consists of by weight:
Hydrocarbon-type oil: 70 ~ 90 parts;
Alcohols oil: 15 ~ 30 parts;
Catalyst: 0.5 ~ 1.5 part;
Adjusting agent: 0.5 ~ 1 part;
Said components is mixed, stirs 1 hour at normal temperatures.
Concrete further, the hydrocarbon mixture that described hydrocarbon-type oil is made up of alkane, alkene, cycloalkane, aromatic hydrocarbon, polycyclic aromatic hydrocarbon.
Concrete further, the alcohol-based mixtures that described alcohols oil is made up of n-butanol, isobutanol, octanol.
Concrete further, described catalyst and adjusting agent change the surface nature of mineral and the feature of ore pulp, improves the selective of floatation process, accelerate and improve flotation conditions.
The invention has the beneficial effects as follows: after using above-mentioned medicament, there is taste light, non-stimulated, foaming characteristic is strong, selective good, consumption is few, the features such as foaming abundancy is even have good foaming effect, can maximize and improve coal particle hydrophobicity, increase particle surface and contaminant surface hydrophobic difference, existing basis is improved clean coal yield 3% ~ 5% percentage point, the size of bubble in coal slurry and motion state can be changed, reduce the power consumption to Aerated stirring in ore pulp, and the froth bed of flotation needs can be formed on mineral slurry level, and the bubble compactness of product is stablized, selective good, reaction speed is fast, do not affect by temperature and pH value.
