The invention provides an ore grinding aid, which consists of the following components in percentage by weight: 25 to 50 percent of polyacrylamide, 18 to 30 percent of sodium carboxymethylcellulose, 3 to 10 percent of glycol, 3 to 10 percent of polyethylene glycol, 3 to 10 percent of Tween, 3 to 8 percent of silicon oil, 3 to 8 percent of ethylic acid, 3 to 8 percent of polyacrylic acid and 2 to 5 percent of chelant. The ore grinding aid can be applied to accurately grinding a gold ore, a copper ore, an iron ore, a molybdenum ore, an aluminum ore, a nickel ore, a zinc ore and the like, and can improve production efficiency, yield and the fineness of accurately ground ores.
Description
Technical field:
The present invention relates to a kind of grinding aid of particulate state original state raw material crushing, in particular, the present invention relates to usefulness is pulverized in a kind of pulverizing that is used in granulate material in mining industry or the extractive industry in particular for ore, concentrate ore grinding aid.
Background technology:
In mining industry and extractive industry, usually implement the pulverizing or the fragmentation of granulate material.For example, the ore dressing of the ore that obtains from the mine usually needs ore carried out fragmentation so that reduce the granularity of ore and expose required mineral surface for ore dressing process.Particularly produce concentrate from ore, from the flotation process of ore or concentrate leaching mineral, and physical separation method such as gravity separation, electrostatic separation are relevant with the magneticseparation method.Similarly, many other mineral processing methods need the size reduction of ore or concentrate so that the power of raising mineral processing process is acquired economic ratio.
Grinding is pulverizing or broken a kind of common method of granulate material.Grinding medium also can add in the shredder.If grinding medium is different from the granulate material that is broken, then this Ginding process is called the ectosome grinding.If the collision between granulate material itself causes grinding and does not add other grinding medium, then is called from body and grinds.
The ore grinding aid can reduce the exploitation and the broken cost of ore, improves the production efficiency of ore and increases the output of ore and the fineness of raising ore.At present, the ore grinding aid has extensively applied to the exploitation and the grinding of various metallic ores.
The ore grinding aid is called the grinding process admixture of ore again, is grinding aid effect of playing that adds when the ore grinding and don't the additive that damages the performance of ore own, and its add-on generally should not surpass the 0.5wt% of ore quality.In ore correct grinding process, the energy of the overwhelming majority is transformed into heat energy and wastes, and descends rapidly owing to the fine particle clustering phenomena causes finish grinding efficient when the ore fineness increases.In order to improve this situation, the best way is exactly to add the ore grinding aid in the correct grinding process, adds a spot of grinding aid in grinding machine, just can significantly improve the efficient of ore correct grinding, and can effectively improve the output of concentrate.The application of ore grinding aid is of great immediate significance to China's energy-saving and emission-reduction, the use of ore grinding aid can improve the fine ore yield of unit time, reduces grinding pow consumption, and can effectively improve the fineness of fine ore, for the smelting of follow-up metal provides good basis.
At present commercially available ore grinding aid is single heavy chemicals or by composite the making of several industrial chemicals simple physical, is used as the following kind of mainly containing of ore grinding aid: 1. alcohols material: as ethylene glycol, Diethylene Glycol, propylene glycol etc.; 2. amine substance: as trolamine, tri-isopropanolamine, acid amides etc.; 3. unsaturated fatty acids: as stearic acid, oleic acid etc.; 4.: salt, as Sodium hexametaphosphate 99, sodium stearate etc.; 5.: mineral substance, as talcum powder, flyash, coke, coal etc.; 6.: other, as the interpolymer of styrenic, melamine formaldehyde (MF), maleic anhydride derivative etc.
Now the grinding aid of widely applying is the single or compound product of above-mentioned industrial chemicals, and its cost is higher, and grinding aid have a system instability, the result of use fluctuation ratio is bigger.
Summary of the invention:
In order to solve the problems of the technologies described above, the objective of the invention is to invent a kind of ore grinding aid, the more traditional grinding aid of cost is low, and system good stability, can be applied to the correct grinding of ores such as gold mine, copper mine, iron ore, molybdenum ore, aluminium ore, nickel minerals, zinc ore, adopt the application's ore grinding aid can enhance productivity, improve productive rate, and can improve the fineness of the ore behind the correct grinding.
To achieve these goals, the technical solution used in the present invention is as follows:
A kind of ore grinding aid is made up of polyacrylamide, Xylo-Mucine, ethylene glycol, polyoxyethylene glycol, tween, silicone oil, acetic acid, polyacrylic acid and intercalating agent, and each components contents is respectively: polyacrylamide: 25-50wt%; Xylo-Mucine: 18-30wt%; Ethylene glycol: 3-10wt%; Polyoxyethylene glycol: 3-10wt%; Tween: 3-10wt%; Silicone oil: 3-8wt%; Acetic acid: 3-8wt%; Polyacrylamide: 3-8wt%; Intercalating agent: 2-5wt%.
Preferably, described ore grinding aid, each components contents is respectively: polyacrylamide: 25-40wt%; Xylo-Mucine: 20-30wt%; Ethylene glycol: 5-10wt%; Polyoxyethylene glycol: 5-10wt%; Tween: 5-10wt%; Silicone oil: 3-5wt%; Acetic acid: 3-5wt%; Polyacrylamide: 3-5wt%; Intercalating agent: 2-5wt%.
Preferred, described ore grinding aid, each components contents is respectively: polyacrylamide: 32wt%; Xylo-Mucine: 26wt%; Ethylene glycol: 8wt%; Polyoxyethylene glycol: 8wt%; Tween: 8wt%; Silicone oil: 5wt%; Acetic acid: 5wt%; Polyacrylamide: 5wt%; Intercalating agent: 3wt%.
Wherein, described intercalating agent can be selected from one or more in ethylenediamine tetraacetic acid (EDTA) (EDTA), nitrilotriacetic acid (NTA), diethylene triaminepentaacetic acid(DTPA), citric acid (CA), the tartrate (TA).
Wherein, described silicone oil can be selected from one or more in methyl-silicone oil, ethyl silicon oil, phenyl silicone oil, Methyl Hydrogen Polysiloxane Fluid, methyl hydroxy silicon oil or the hydroxyl hydrogen silicone oil.
Wherein, the preferred solubility silicone oil of described silicone oil.
Wherein, optional in polysorbas20, picture and text 21, polysorbate40, polysorbate60, tween 61, tween 80, sorbimacrogol oleate100 or polysorbate85 one or more of described tween.
Employed polyacrylamide (PAM) and Xylo-Mucine (CMC) can produce lubrication to the rough powder of various metallic ores in the grinding aid, reduce the resistance that grinds; Employed complexed surfactant in the grinding aid, ethylene glycol, polyoxyethylene glycol and tween can effectively reduce the surface tension of ore, reduce viscosity, thereby reduce the resistance that grinds; Acetic acid in the grinding aid and vinylformic acid can with oxide compound or the composite oxides generation chemical reaction in the mineral dust, help to reduce the hardness of ore, and help the smelting of metal; Intercalating agent can play good dispersion effect to each component in the grinding aid, helps making performance synergy between each component.
In addition, the present invention also provides a kind of preparation method of above-mentioned ore grinding aid, it may further comprise the steps: add polyacrylamide, Xylo-Mucine, ethylene glycol, polyoxyethylene glycol, tween, silicone oil, acetic acid, polyacrylic acid and intercalating agent in reactor respectively, be heated to 50-85 ℃, stir, obtain ore grinding aid product.
