Description
Technical field
The present invention relates to a kind of composite chemical for floatating of zinc oxide and its preparation method and application, belong to ore dressing floating agent
Technical field.
Background technology
Zinc is mainly used for zinc-plated industry, and the produced zinc in the world is greatly used for zinc-plated industry, remaining to be mainly used for
Diecasting alloys, brass, milling material etc..The advantages of high-purity silver-zinc battery has small at present, and energy is big, be used as aircraft,
This quasi-instrument such as instrument power of spaceship.The organic compound zinc diaryl dithiophosphates and dialkyl dithio phosphorus of zinc
Sour zinc can be used as allocating I. C. engine oil, improve wear-resistant, anti-oxidant and corrosion resistance；As a kind of for mainly containing Zn-ef ficiency
Granular composite nitrogen fertilizer Zinc-Urea, its main function be can strengthen the Gen Duogen of crops, the thick leaf of stem is big, twig is sturdy, grain is full
Fringe is big.
In recent years, the consumption of world's zinc gradually increases, and zinc is in deficient resources for a long time in China, and supply falls short of demand, and with
The increasingly exhausted of zinc sulfide ore resource, the recycling of zinc oxide is paid attention to.But the zinc oxide ore grade in China is relatively low, return
Receive index it is undesirable, substantial amounts of zinc oxide ore discarded or stacked for a long time zinc oxide ore recycling difficult point mainly have it is following some,
First, argillization is serious, causes sludge to be covered in mineral surface and hamper contact between medicament and mineral, so as to reduce collecting
Efficiency；Second, the flotation conditions of different minerals differ in ore, the interference phenomenon between the medicament in each stage is serious, third, oxidation
Zinc mineral surface often by oxidation iron pollution, loses original flotation performance.
Currently for zinc oxide floating agent, generally there is an amine and xanthate collectors, but it is simple using amine or
Xanthate collectors effect is undesirable, and index is relatively low, and number of patent application discloses a kind of zinc oxide for " 201610629984.9 "
The preparation method of ore deposit collecting agent, it is 1 ~ 2 in molar ratio by oleic acid formicester and methanol that this method, which is,：1 ~ 3 ratio is mixed to get molten
Liquid 1, is then 1 ~ 2 in mass ratio by the sodium hydroxide that mass percentage concentration is 25 ~ 30%：2 ~ 3 ratio is added in solution 1,
Obtained solution 2 when stirring reaction 2 ~ 2.5 is small at 120 ~ 125 DEG C, is then 1 ~ 2 in mass ratio by phosphorus pentoxide at 90 DEG C：
1.5 ~ 4 ratio is added in solution 2 and stirred, and last repeated hydrogenation sodium oxide molybdena is neutralized and is dried to obtain, although the collecting agent can be to oxidation
Zinc is acted on collecting, but poor to the collecting ability of the zinc oxide of high mud, and recovery index is relatively low, and exploitation one kind is directed to low-grade height
The composite chemical for floatating of the zinc oxide ore of mud has great importance.
The content of the invention
It is right it is an object of the present invention to providing a kind of composite chemical for floatating of zinc oxide and its preparation method and application
The higher zinc oxide ore of low-grade clay content, without prior desliming, directly carries out flotation, and recovering effect is good, and index is preferable, this
Outside, using this composite chemical for floatating, the usage amount of vulcanized sodium is reduced, has saved reagent cost.
Zinc oxide composite chemical for floatating of the present invention, is made by the component of following mass parts：30 ~ 40 parts of acetic acid octadecylamine, ten
15 ~ 20 parts of diamines, 15 ~ 20 parts of primary amine, 30 ~ 40 parts of methyl isobutyl carbinol, 7 ~ 15 parts of copper sulphate, 3 ~ 5 parts of emulsifying agent.
The emulsifying agent is p-Octylphenol polyoxyethylene ether.
The second object of the present invention is the provision of the preparation method of zinc oxide composite chemical for floatating, and concrete operations are as follows：
Acetic acid octadecylamine, lauryl amine, primary amine and copper sulphate solid are taken in container, then into container add methyl isobutyl carbinol and
Emulsifying agent, and mixed solution is uniformly mixing to obtain at 30 ~ 40 DEG C, mixed solution is then subjected to emulsification treatment, is aoxidized
Zinc composite chemical for floatating.
The equipment of the emulsification treatment is high-speed shearing emulsion machine.
The emulsification times are 10 ~ 30min, and emulsifying temperature is 25 ~ 35 DEG C.
The third object of the present invention is to apply zinc oxide composite chemical for floatating in the low-grade high mud zinc oxide ore of flotation
In, mineral are crushed first, ore grinding to granularity in mass accounts for 75 ~ 90% less than 0.074mm, then plus water size mixing it is dense to ore pulp
Spend for 50 ~ 65%, based on raw ore per ton, 120 ~ 200g/t calgons and 120 ~ 180g/t waterglass are added into ore pulp, then
300 ~ 500g/t vulcanized sodium is added, 120 ~ 200g/t of the zinc oxide composite chemical for floatating is eventually adding and zinc oxide ore is returned
Receive.
Contain acetic acid octadecylamine zinc oxide ore in this composite drug, its collecting effect to zinc oxide is preferable, flotation froth
Viscosity is relatively low, and collecting ability is strong, and pharmacy effect is relatively stablized, thus it is good for low-grade zinc oxide ore recovering effect, with 12
Supplemented by amine and primary amine, increase the collecting ability to zinc oxide, particularly collecting performance of the primary amine to smithsonite is stronger, composite drug
Middle copper sulphate has primarily served the effect of activation, and the oxide ore surface active after can vulcanized sodium be vulcanized, strengthens collecting effect, first
Mixture is fully dissolved, played a role, which is directed to oxygen as solvent by base isobutyl carbinol and emulsifying agent
It is stronger to change the collecting effect of zinc ore, improves the rate of recovery and grade of zinc oxide ore.
Compared with existing zinc oxide floating agent, the beneficial effects of the present invention are：
（1）The zinc oxide ore treatment effect that the zinc oxide flotation composite drug of the present invention is high to low-grade clay content is preferable, zinc
The rate of recovery and grade are improved at the same time.
（2）The zinc oxide flotation composite drug of the present invention to raw ore in use, without carrying out desliming, direct flotation, technique
Flow is simple.
（3）The zinc oxide flotation composite drug of the present invention reduces the usage amount of vulcanized sodium, has saved reagent cost.
（4）The zinc oxide flotation composite drug of the present invention is environmentally safe, environmentally protective.
