Abstract
The invention discloses a sodium-modified kaolin tailing. The technical scheme is as follows: the sodium-modified kaolin tailing is composed of kaolin tailing, magnesium oxide, sodium carbonate, instant sodium silicate, polyvinyl alcohol and hydroxypropyl methylcellulose. The production method of the sodium-modified kaolin tailing comprises the following steps: inputting the sodium-modified kaolin tailing materials into a mill, and milling into powder, thereby obtaining the sodium-modified kaolin tailing. The sodium-modified kaolin tailing fully utilizes the solar energy, the alternate rain and wind and the four seasons, promotes the natural weathering effect on the kaolin tailing raw ores, enhances the disintegration effect on the kaolin tailing raw ores, and accelerates the dispersion of various minerals in the tailing raw ores. The sodium-modified kaolin tailing is soft, and can be easily dispersed and suspended in water, and has better plasticity, binding property, electrical insulation properties, fire resistance and other physicochemical properties. The sodium-modified kaolin tailing is suitable for producing fillers of papermaking, paints, ceramics, rubber and refractory materials.
Description
Technical field
The present invention relates to sodium and process, be specifically related to the Kaolin Tailings after a kind of sodium.
Background technology
Kaolin is a kind ofly to take kaolinite family clay mineral and be main clay and tonstein, and how matt, when matter is pure, face is fine and smooth in vain, can be with ash, yellow, brown isochrome when impure, and outward appearance can be loose soil block shape and fine and close state sillar shape according to origin cause of formation difference.
Take the kaoline deposit origin cause of formation as basis, the difference of the aspects such as feature, ore material composition is deposited in one-tenth ore deposit geology, geographical conditions, deposit scale, ore body form and the tax embodying according to different mineralization, 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 stronger, chiltern massfraction≤50%; Sandy kaoline: matter is soft, plasticity-a little less than, 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, can not be directly used in sodium processes, normal employing pulverizer is broken for tiny particle and carries out sodium processing, is easy to destroy kaolinic crystalline structure.
Sodium is not carried out follow-up complementary modification after processing, and can not improve the quality of kaolin product comprehensively.
Mineral Resources in China 80% is intergrowth mineral, and a large amount of valuable resources retain among mine tailing, and tailings impoundment need to take a large amount of soils.A lot of Tailings Dams exceed the time limit or excess load is used, and even violation operation, makes Tailings Dam have great potential safety hazard, and people's property and the life security of surrounding area are caused to serious threat.
Kaolin produces a large amount of mine tailings in recovery process, and Kaolin Tailings is hard kaoline mostly, and production utilization ratio 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 comprised 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, good 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.
