Description
Technical field
The present invention relates to composite chemical for floatating of a kind of zinc oxide and its preparation method and application, belong to ore dressing floating agent
Technical field.
Background technique
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..High-purity silver-zinc battery has small in size, the big advantage of energy at present, 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 deploying 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 are can to make that the Gen Duogen of crops is strong, stem thickness leaf 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
Zinc sulfide ore resource it is increasingly exhausted, the recycling of zinc oxide is paid attention to.But the zinc oxide ore grade in China is lower, returns
Receipts index is undesirable, and the recycling difficult point that zinc oxide ore was discarded or stacked for a long time to a large amount of zinc oxide ore mainly has the following,
First is that argillization is serious, causes sludge to be covered on mineral surface and hamper contact between medicament and mineral, to reduce collecting
Efficiency；Second is that the flotation conditions of different minerals are different in ore, the interference phenomenon between the medicament in each stage is serious, third is that oxidation
Zinc mineral surface is often oxidized iron pollution, loses original flotation performance.
Be directed to zinc oxide floating agent at present, generally there is an amine and xanthate collectors, but it is simple using amine or
Xanthate collectors effect is undesirable, and index is lower, and number of patent application is that " 201610629984.9 " disclose a kind of zinc oxide
The preparation method of mine collecting agent, this method be the ratio that oleic acid formicester and methanol are 1 ~ 2:1 ~ 3 in molar ratio is mixed to get it is molten
Then liquid 1 ratio that the sodium hydroxide that mass percentage concentration is 25 ~ 30% is 1 ~ 2:2 ~ 3 in mass ratio is added in solution 1,
It is stirred to react 2 ~ 2.5 hours obtained solutions 2 at 120 ~ 125 DEG C, is in mass ratio then 1 ~ 2 by phosphorus pentoxide at 90 DEG C:
1.5 ~ 4 ratio is added in solution 2 and stirs, and last repeated hydrogenation sodium oxide molybdena neutralization is dried to obtain, although the collecting agent can be to oxidation
Zinc has collecting effect, but poor to the collecting ability of the zinc oxide of high mud, and recovery index is lower, develops a kind of for low-grade height
The composite chemical for floatating of the zinc oxide ore of mud has great importance.
Summary of the invention
It is right one of the objects of the present invention is to provide composite chemical for floatating of a kind of zinc oxide and its preparation method and application
The low-grade higher zinc oxide ore of clay content does not have to prior desliming, and directly progress flotation, recovering effect is good, and index is ideal, this
Outside, using this composite chemical for floatating, the usage amount of vulcanized sodium is reduced, reagent cost has been saved.
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 emulsifier.
The emulsifier 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:
Take acetic acid octadecylamine, lauryl amine, primary amine and copper sulphate solid in container, then into container be added methyl isobutyl carbinol and
Emulsifier, 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, by mineral, broken, ore grinding to granularity in mass is less than 0.074mm and accounts for 75 ~ 90% first, then plus water size mixing it is dense to ore pulp
Degree is 50 ~ 65%, and based on raw ore per ton, 120 ~ 200g/t calgon and 120 ~ 180g/t waterglass are added into ore pulp, then
300 ~ 500g/t vulcanized sodium is added, is eventually adding 120 ~ 200g/t of the zinc oxide composite chemical for floatating and zinc oxide ore is returned
It receives.
Contain acetic acid octadecylamine zinc oxide ore, flotation froth preferable to the collecting effect of zinc oxide in this composite drug
Viscosity is lower, and collecting ability is strong, and pharmacy effect is more stable, 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, especially primary amine is stronger to the collecting performance of smithsonite, composite drug
Middle copper sulphate has primarily served the effect of activation, and the oxide ore surface active after can vulcanizing vulcanized sodium enhances collecting effect, first
Mixture is sufficiently dissolved, is played a role as solvent by base isobutyl carbinol and emulsifier, which is directed to oxygen
The collecting effect for changing zinc ore is stronger, 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 flotation composite drug of the invention zinc oxide ore treatment effect high to low-grade clay content is preferable,
The rate of recovery and grade of zinc are improved simultaneously.
(2) zinc oxide flotation composite drug of the invention is not in use, have to carry out desliming, direct flotation, technique to raw ore
Process is simple.
(3) zinc oxide flotation composite drug of the invention reduces the usage amount of vulcanized sodium, has saved reagent cost.
(4) zinc oxide flotation composite drug no pollution to the environment of the invention, it is environmentally protective.
