Description
Technical field
The present invention relates to mineral and grind field, particularly a kind of mineral grinding aid and application thereof.
Background technology
In mineral products field, usually need ore to be carried out pulverizing to reduce the granularity of ore from the ore dressing of the ore of mine excavation, for ore dressing process exposes required mineral surface.
Grinding is a kind of common method of ore grinding.Ore powder is in crushing process, along with the fragmentation of particle, fine particle, at formation illusion macrobead together of reuniting, makes process of lapping become difficulty, the balance even forming grinding and reunite, extra-fine grinding cannot be realized, ore grain size below 10 μm, often increases by 1% in breeze, and its ore grinding time will increase by 2%, the wearing and tearing of power consumption and steel ball liner plate, all corresponding increase by 2%.Thus cause mill efficiency to decline rapidly.In order to improve this situation, this area often adds grinding aid.
Existing grinding aid usually comprises following kind: one is alcohols material, such as ethylene glycol, propylene glycol etc., two is amine substances, as trolamine, tri-isopropanolamine, acid amides etc., three is unsaturated fatty acids materials, such as stearic acid, oleic acid etc., four is salts substances, such as Sodium hexametaphosphate 99, sodium stearate etc., five is mineral substance materials, such as talcum powder, flyash, coke, coal etc., other also comprise the interpolymer, melamine formaldehyde (MF), maleic anhydride derivative etc. of styrenic, and the single or mixture of mentioned kind is as grinding aid often.Although existing grinding aid can improve mill efficiency to a certain extent, its effect is still undesirable, there is very large room for promotion.
Summary of the invention
Goal of the invention of the present invention is: for above-mentioned Problems existing, provides a kind of mineral grinding aid that can significantly improve mill efficiency.
The technical solution used in the present invention is such: a kind of mineral grinding aid, is grouped into by the following one-tenth counted in mass ratio:
Water glass 10-40%; Sodium hexametaphosphate 99 5-25%; Trolamine 5-25%; All the other are water.
Contriver studies discovery, in mineral powder breakdown mill process, usually can be subject to the effect of different sorts stress, causes material form crackle and expand, is then pulverized.According to lattice Lifei law, the minimum stress needed for brittle rupture is directly proportional to the specific surface energy of material.Obviously, reduce the surface energy of particle, can reduce and make its required stress that ruptures.From the process of ore particles fracture, above-mentioned mineral grinding aid molecule can reduce the external stress needed for crack propagation in the absorption of fresh surface, promotes the expansion of crackle.So say from this point, the chemical substance that can reduce solid surface energy can reduce the intensity of particle, thus can improve crush efficiency or reduce Grin-ding energ7.
Above-mentioned have between surface-active its composition of mineral grinding aid mutually work in coordination with, surface energy can be eliminated, reduce the reunion of fine particle in process of lapping, after employing grouping screening measure, granularity can be met the requirements of mineral and send to choosing point in time, the mineral making granularity not reach requirement are got back to grinding machine and are regrinded, and both improve concentrate grade like this, turn improve the mill efficiency of grinding machine and the rate of recovery of concentrate.Meanwhile, also just decrease energy consumption, reduce the wearing and tearing frequency of ball-grinding machine.
As preferred technical scheme, this mineral grinding aid is grouped into by the following one-tenth counted in mass ratio:
Water glass 20%; Sodium hexametaphosphate 99 10%; Trolamine 10%; All the other are water.
Adopt the grinding aid that the component of this ratio obtains, the rate of recovery of its mill efficiency and concentrate is higher.
As preferred technical scheme, this mineral grinding aid is grouped into by the following one-tenth counted in mass ratio:
Water glass 10-40%; Sodium hexametaphosphate 99: 5-25%; Trolamine: 5-25%; Tripoly phosphate sodium STPP 3 ~ 10%; All the other are water.
On the basis of aforementioned three kinds of compositions, add the tripoly phosphate sodium STPP of proper ratio, mill efficiency and the concentrate rate of recovery can be improved further.
As further preferred technical scheme, this mineral grinding aid is grouped into by the following one-tenth counted in mass ratio:
Water glass 10-40%; Sodium hexametaphosphate 99: 5-25%; Trolamine: 5-25%; Tripoly phosphate sodium STPP 3 ~ 10%; Multi-amidocyanogen sodium phosphate 3 ~ 10%; All the other are water.
On the basis of aforementioned four kinds of compositions, add the polyamino Alendronate of proper ratio, mill efficiency and the concentrate rate of recovery can be improved further.
As further preferred technical scheme, this mineral grinding aid is grouped into by the following one-tenth counted in mass ratio:
Water glass 10-40%; Sodium hexametaphosphate 99: 5-25%; Trolamine: 5-25%; Tripoly phosphate sodium STPP 3 ~ 10%; Multi-amidocyanogen sodium phosphate 3 ~ 10%; Calcium lignin sulphonate 1 ~ 5%; All the other are water.
On the basis of aforementioned five kinds of compositions, add the calcium lignin sulphonate of proper ratio, mill efficiency and the concentrate rate of recovery can reach more excellent.
Water glass of the present invention is preferably liquid sodium silicate.
The present invention also provides the application of above-mentioned mineral grinding aid, and the technical scheme of employing is: described mineral grinding aid is used for iron ore, gold mine, Pb-Zn deposits, copper mine at the fine grinding in ball milling stage.
As preferred technical scheme: when refining, the quality adding described mineral grinding aid is treat the 0.05-1.2% of ore grinding amount.
In sum, owing to have employed technique scheme, the invention has the beneficial effects as follows: under identical raw ore condition, add grinding aid of the present invention, considerable influence can not be produced to ore grade, and the productive rate of concentrate has and significantly promotes, improve more than 13%, the concentrate rate of recovery also significantly promotes, improve more than 39%, mill efficiency significantly improves.The particle that in concentrate, particle diameter is less than 75 μm simultaneously, namely the percentage composition of the particle of "-75 μm " adds about 10%.In addition, decrease the consumption of electric energy equal energy source, reduce the wearing and tearing frequency of ball-grinding machine.
