Description
Technical field
The present invention relates to a kind of coal flotation agent, belong to auxiliary chemicals technical field.
Background technology
Flotation coal separation method is to coal on the basis of the different characteristic of physicochemical properties of mineral surfaces is considered
A kind of coal preparation method that particle is sorted, is also a kind of coal preparation method being widely used at present.Coal particles its own face is all
Hydrophobicity is there is, while adding after flotation agent, the hydrophobicity on coal surface can be also improved, and pass through each PROCESS FOR TREATMENT, coal
Charcoal particle can float over the ore deposit liquid surface of flotation device, and can be recycled in the form of foam.
The flotation agent that flotation coal separation is utilized plays an important role to coal separation effect, in traditional flotation coal preparation technique, fortune
The grain of the coal in coal separation mud is treated with collecting agent and stone mud is ground different compatibilities and selectivity, so as to form hydrophobic cleaned coal
With the tiny group of hydrophily coal slime, foaming agent then there are different floatings to take speed out of the tiny group of cleaned coal and coal slime of formation
Rate, and then a relative cleaned coal froth bed and coal slime layering are constantly formed in floating-upward process, finally successfully realize flotation point
From.Classified because of flotation agent used in conventional art using plurality of raw materials and store and add, equipment investment is big, technology is relatively multiple
It is miscellaneous, and each component is complex in the technological adjustment of flotation site, it is higher to the skill requirement of operating personnel and random bigger than normal.
The content of the invention
It is an object of the invention to provide a kind of new coal flotation agent, solve traditional flotation agent need to classify storage and
The drawbacks of addition, with flotation effect it is good, disposably add the characteristics of.
Coal flotation agent of the present invention is made up of the raw material of following mass percent：
Collecting agent 60~75%, foaming agent 20~40%, complexing agent 1~5%.
Preferably, it is made up of the raw material of following mass percent：
Collecting agent 70%, foaming agent 27%, complexing agent 3%.
Wherein：
The collecting agent is made up of the raw material of following mass percent：Triethyl phosphate 60~70%, diesel oil 20~30%,
Dichloromethane 10~20%, preferably phosphoric acid triethyl 70%, diesel oil 20%, dichloromethane 10%；The addition of dichloromethane can
Strengthen the mobility of flotation agent so that the flow effect of flotation agent is more preferable, meanwhile, the density of triethyl phosphate is between diesel oil and two
Between chloromethanes, in floatation process, the mobility of molecule is strengthened, and enhances separating effect.
The foaming agent is that abienol accounts for 80wt%, 12 in the mixture of abienol and sodium lauryl sulfate, mixture
Alcohol sodium sulphate accounts for 20%.
The complexing agent is the extremely strong graphene of adsorption capacity, and graphene adsorbent can adsorb the heavy metal thing in coal
, there is heavy metal pollution during the reduction follow-up use of coal in matter.
Beneficial effects of the present invention are as follows：
(1) coal flotation agent of the invention is disposably added when in use, can be according to the composition of coal, appropriate adjustment
The consumption of flotation agent, and composition and ratio when using same coal stablizes relatively, specific aim is good, it is to avoid in conventional method point
The problem of classification is using one pack systems such as collecting agent, foaming agents, it also avoid the blindness and randomness during addition proportioning；
(2) coal flotation agent of the invention is high to the selectivity of coal, and usage amount is more saved, and can be recycled.
Embodiment
The present invention is described further with reference to embodiments.
Embodiment 1
Coal flotation agent is made up of the raw material of following mass percent：
Collecting agent 70%, foaming agent 27%, graphene 3%.Wherein：
