Description
Technical field
The present invention relates to sodium process, be specifically related to the Kaolin Tailings after a kind of sodium.
Background technology
Kaolin is a kind of based on the clay of kaolinite race clay mineral and tonstein, and how matt, when matter is pure, face is fine and smooth in vain, and as can with ash, yellow, brown isochrome time impure, outward appearance can be loose soil block shape and densifie state sillar shape according to origin cause of formation difference.
Based on the kaoline deposit origin cause of formation, according to the difference of the aspect such as Ore-forming geology, geographical conditions, deposit scale, Ore body morphology and bearing features, ore material composition that different mineralization embodies, kaoline deposit is divided into three types: hard kaoline: matter is hard, without plasticity-, tool plasticity-after pulverizing fine grinding; Soft kaolin: matter is soft, plasticity-is comparatively strong, chiltern massfraction≤50%; Sandy kaoline: matter is soft, plasticity-is more weak, chiltern massfraction >=50%.
In Kaolin Mining Region, usage mining machine carries out mechanical mining kaolin raw ore, excavate out be a kind of compact mass kaolin raw ore, the volume of kaolin raw ore is larger, sodium process can not be directly used in, normal employing pulverizer is broken for tiny particle and carries out sodium process, is easy to destroy kaolinic crystalline structure.
Do not carry out follow-up complementary modification after sodium process, the quality of kaolin product can not be improved comprehensively.
Mineral Resources in China 80% is intergrowth mineral, and a large amount of valuable resource retains among mine tailing, and tailings impoundment needs to take a large amount of soil.A lot of Tailings Dam exceeds the time limit or excess load uses, and even violation operation, makes Tailings Dam there is great potential safety hazard, causes serious threat to people's property of surrounding area and life security.
Kaolin produces a large amount of mine tailings in recovery process, and Kaolin Tailings is hard kaoline mostly, and Commercial cultivation rate is lower.
Summary of the invention
The object of the invention is to overcome weak point in prior art, the Kaolin Tailings after a kind of sodium is provided.
Kaolin Tailings batching after sodium is made up of Kaolin Tailings, magnesium oxide, sodium carbonate, quick dissolved sodium silicate, polyvinyl alcohol and Vltra tears.
The production method of the Kaolin Tailings after sodium: by abrasive dust in the Kaolin Tailings batching input grinding machine after sodium, the meal after abrasive dust is the Kaolin Tailings after sodium.
Kaolin has that whiteness is high, matter is soft, easy dispersion suspension in water, good plasticity-, higher cohesiveness, excellent electrical insulation capability and the physico-chemical property such as resistivity against fire preferably.
Magnesium oxide has the general character of basic oxide, belongs to gelling material, can improve the colloidal property of Kaolin Tailings.
Sodium carbonate has the general character and the thermostability of salt, soluble in water, and its aqueous solution, in alkalescence, is the main raw material of sodium in the present invention.
Quick dissolved sodium silicate is white powder material, can rapid solution in water, have that cohesive force is strong, intensity is higher, acid resistance, good heat resistance, the feature of alkali resistance and poor water resistance.
Polyethenol series white solid, external form divide cotton-shaped, particulate state, Powdered three kinds; Nonpoisonous and tasteless, particulate state can be dissolved in 80--90 DEG C of water, pulverous other powders pre-dispersed after can dissolve at normal temperatures.There is good viscosity, polymerizability, cohesiveness and water-retentivity.
Vltra tears has thickening capabilities, salt discharge, pH stability, water-retentivity, dimensional stability, excellent film-forming properties and the feature such as resistance to enzymatic, dispersiveness and cohesiveness widely.
The present invention is achieved by following technical proposals:
1, the Kaolin Tailings batching after sodium is made up of following component by weight percentage: Kaolin Tailings flap 90 ~ 98%, quick dissolved sodium silicate 0.1 ~ 5%, polyvinyl alcohol 0.1 ~ 5% and Vltra tears 0.01 ~ 3%.
The production method of the Kaolin Tailings 2, after sodium: by abrasive dust in the Kaolin Tailings batching input grinding machine after sodium, particle fineness≤0.074 millimeter, the meal after abrasive dust is the Kaolin Tailings after sodium.
3, the production method of Kaolin Tailings flap: (1) by Kaolin Tailings mixture input fermentation vat, more slowly added in Kaolin Tailings mixture by water and soak sodium, sodium soak time is 24 ~ 72 hours; (2) take out the Kaolin Tailings mixture after soaking, stir in input biaxial rneader, input after stirring in extrusion machine and be extruded into Kaolin Tailings flap, Kaolin Tailings thickness of flap≤3 millimeter; (3) be transported in rotary type stoving oven by Kaolin Tailings flap and dry, it is 1 ~ 3 hour that drying time controls, and bake out temperature controls at 80 ~ 100 DEG C, and the Kaolin Tailings flap water content after oven dry is 10 ~ 15%, and PCm is weight percentage.
4, the batching of Kaolin Tailings flap is made up of following component by weight percentage: Kaolin Tailings mixture 65 ~ 85% and water 15 ~ 35%.
5, the production method of Kaolin Tailings mixture: stir in the batching of Kaolin Tailings mixture input stirrer is Kaolin Tailings mixture after stirring.
6, the batching of Kaolin Tailings mixture is made up of following component by weight percentage: the Kaolin Tailings 92 ~ 98% after weathering, magnesium oxide 0.5 ~ 5% and sodium carbonate 0.5 ~ 5%.
7, Kaolin Tailings raw ore needs the time weathering more than two winters, Kaolin Tailings after being the weathering of fine particle from the raw ore disintegration of large block compact, pick obvious visible barren rock block, vegetable fibre and other earth impurity, Kaolin Tailings particle fineness≤5 millimeter after weathering.
The production method of the Kaolin Tailings after sodium takes first sodium to carry out compounding ingredient again, sodium carbonate and quick dissolved sodium silicate, polyvinyl alcohol and Vltra tears generation chemical reaction can be avoided, give full play to raw-material respective characteristic in batching, and obtain complementation, guarantee the Kaolin Tailings inner quality after sodium.
The present invention makes full use of sun power, wind and rain replaces and with the passage of time, promote the weathering effect to Kaolin Tailings raw ore, improves the disintegration effect of Kaolin Tailings raw ore, accelerates the dispersion of various mineral in mine tailing raw ore.
