Description

A kind of coal flotation agent
Technical field
The invention belongs to coal finishing technology fields, and in particular to a kind of flotation agent for coal flotation.
Background technique
Flotation coal separation method be using on the basis of coal particles Surface Physical Chemistry property different characteristic to coal particles into A kind of coal preparation method of row sorting, and a kind of coal preparation method being widely used at present.All there is hydrophobic on coal particles surface Property, while flotation agent is added and improves its hydrophobicity, the mine liquid table of flotation device can be floated on by various process coal particles Face, it is final to recycle.
The flotation agent that flotation coal separation utilizes plays an important role to coal separation effect.And in traditional flotation coal preparation technique, it uses Collecting agent treats coal grain in coal separation mud and spoil mud have different compatibility and selectivity, to formed hydrophobic cleaned coal and The tiny group of hydrophily coal slime, and foaming agent then there is different floatings to take speed out of the cleaned coal of formation and the tiny group of coal slime Degree, and then an opposite cleaned coal froth bed and coal slime layering are constantly formed, finally successfully realize FLOTATION SEPARATION.Because of traditional technology Flotation agent used uses plurality of raw materials classification storage and addition, and equipment investment is bigger, technology is relative complex;And each component It is complex in the technology adjustment of flotation site, it is higher to the skill requirement of operator and random bigger than normal.
Summary of the invention
The invention overcomes the deficiencies of the prior art, and provides a kind of coal flotation agents, and formula is relatively stable, once Property addition, specific aim is good, effect is good.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention are as follows: a kind of coal flotation agent, it is raw materials used to press According to following weight: 100-150 parts of commercial recovery base oil, 30-50 parts of fusel oil, 3-7 parts of sodium metasilicate, graphene 2-6 Part, 1-5 parts of lime.
The commercial recovery base oil is the mixture of matter base oil and lighter body in recycling, volume ratio 0.1- 0.5:1-3。
Compared with the prior art, the invention has the beneficial effects that: the present invention is used as using commercial recovery base oil and catches choosing Agent, can efficiently use commercial recovery base oil, while matter base oil is mixed with lighter body in using, and can improve one Cost is reduced, while also can satisfy the technique requirement of flotation.Coal flotation agent using when can be used as one-component add, avoid The addition multi-pipelines such as collecting agent and foaming agent addition respectively, simplifies process flow.Coal flotation agent is to different types of coal difference Floatation process has good flotation effect, improves clean coal yield, reduces cleans ash, adaptable.
Specific embodiment
Embodiment 1
A kind of coal flotation agent, raw materials used according to following weight: 150 parts of commercial recovery base oil, 50 parts of fusel oil, 7 parts of sodium metasilicate, 6 parts of graphene, 5 parts of lime.
The commercial recovery base oil be recycling in matter base oil and lighter body mixture, volume ratio 0.1: 3。
Embodiment 2
A kind of coal flotation agent, raw materials used according to following weight: 100 parts of commercial recovery base oil, fusel oil 30-50 Part, 3 parts of sodium metasilicate, 2 parts of graphene, 1 part of lime.
The commercial recovery base oil be recycling in matter base oil and lighter body mixture, volume ratio 0.5: 1。
Embodiment 3
A kind of coal flotation agent, raw materials used according to following weight: 120 parts of commercial recovery base oil, 40 parts of fusel oil, 4 parts of sodium metasilicate, 5 parts of graphene, 3 parts of lime.
The commercial recovery base oil be recycling in matter base oil and lighter body mixture, volume ratio 0.3: 1.5。
Embodiment 4
A kind of coal flotation agent, raw materials used according to following weight: 130 parts of commercial recovery base oil, 35 parts of fusel oil, 6 parts of sodium metasilicate, 5 parts of graphene, 4 parts of lime.
The commercial recovery base oil be recycling in matter base oil and lighter body mixture, volume ratio 0.2: 2.8。
By taking the coal sample of Linfen coal preparation plant as an example, coal ash is divided into 15%, and the thin mud part less than 0.04mm accounts for 18%, enters Material floatation concentration is 100-120g/L, after coal flotation agent disposably adds.Detailed process are as follows: 1, the output tail after dense-medium separation Coal;2, tail coal enters ore pulp generation bucket generation ore pulp after crushing and screening;3, coal flotation agent is added at one time in premix bucket It is premixed with ore pulp;4, premix, into flotation device flotation;5, the cleaned coal foam of emersion enters cleaned coal bucket and send filters pressing output cleaned coal, Tail coal water enters tailing pit, and filters pressing output tail coal mud is sent in underflow.
With the increase of coal flotation agent dosage, become better and better to the flotation effect of coal sample, scrape bubble the time also accordingly shorten; When coal flotation agent ratio being used to use sec-octyl alcohol and diesel oil as flotation agent, the yield of concentrate is higher, therefore, is reaching same effect When coal composite floating chemical dosage more save, reduce production cost;Simultaneously use composite floating chemical when, scrape bubble the time it is also shorter, Flotation speed faster, improves production efficiency.
Above embodiment is merely exemplary to illustrate the principle of the present invention and its effect, and is not intended to limit the present invention.For Person skilled in the art all without departing from the spirit and scope of the present invention, modifies above-described embodiment or is improved.Cause This, institute is complete without departing from the spirit and technical ideas disclosed in the present invention by tool usually intellectual in all act technical fields At all equivalent modifications or change, should be covered by the claims of the present invention.
