Description

A kind of technique that aluminium hydroxide and concrete admixture are produced from Coaseries kaolin
Technical field：
The present invention relates to a kind of technique that aluminium hydroxide and concrete admixture are produced from Coaseries kaolin, belong to coal measures Kaolinic high level application technology as the second resource field.
Background technology：
There is abundant coal series kaolin soil resource in China, and Coaseries kaolin belongs to the associated minerals of coal, it is difficult to large-scale exploitation Utilize.Al in Coaseries kaolin2O3Content about 40% or so, therefrom extracts the Al for having economic worth higher2O3, make it It is the effective way for improving Coaseries kaolin comprehensive utilization for a kind of new bauxite resource is used.
At present, there are acid system and the class of alkaline process two using the method for Coaseries kaolin production aluminum oxide.Acid system first extracts aluminium salt, Such as aluminium chloride, ammonia-alum, aluminum sulfate, then aluminum oxide is can obtain after aluminium salt is calcined；Alkaline process is to be extracted with alkaline matter Al2O3, common alkaline process has Bayer process, limestone sintering process and soda lime sintering process.In process above method, acid system and visit Ear method need to consume the chemical raw materials such as a large amount of hydrofluoric acid, sulfuric acid, caustic soda, and production cost is higher, and there are no heavy industrialization should Use case；Though lime stone and soda lime sintering process have the advantages that raw material sources are cheap extensively, the method aluminum oxide per ton is carried The residue of aluminum-extracted that 2~2.5 tons of alkalinities will be produced high is taken, the usual residue active component is few, alkalinity is high, it is difficult to directly be subject to Utilize.Substantial amounts of residue of aluminum-extracted piles up not only land occupation, secondary pollution is produced to environment, and reduces kaolin and propose aluminium life The economic benefit of product.
Chinese patent CN103121700A discloses one kind and prepares ultra-fine alumina co-producing white carbon black using Coaseries kaolin Method, by coal series kaolin rock is broken, roasting, alkali leaching, filtering, obtain sodium silicate solution and alkali phase analysis, sodium silicate solution carries out carbonic acid Change treatment obtains orthosilicic acid precipitated filter cakes and desiliconization liquid, orthosilicic acid precipitated filter cakes is aged, is calcined, and obtains white carbon；Alkali Phase analysis use soda lime sintering process, and the clinker of sintering processes is carried out, from efflorescence, water quenching, filtering, to obtain NaAlO2Solution, NaAlO2Solution obtains ultra-fine alumina after carrying out carbonating treatment, roasting.
Chinese patent CN1334240A discloses a kind of technique that super-purity aluminum oxide is produced using Raolinite (soil), is by height Rock (soil) clinker in ridge produces aluminium salt with acid reaction, and aluminium salt adds alkali to form aluminate, efficiently separated the impurity such as Fe, Ti, then Acid adding forms the hyrate of aluminium, disposable to reject basic ion in product after the hyrate of aluminium is through drying, washing.
Chinese patent CN13435079A discloses the technique that a kind of aluminosilicate minerals low-temperature decomposition produces aluminum oxide, By aluminosilicate minerals it is levigate after, mixed in proportion with strong base solution, hydro-thermal reaction is then carried out in high-pressure bottle, Separation of solid and liquid must carry potassium mother liquor and carry aluminium clinker；The leaching filtering of aluminium clinker acid solution will be proposed, then pH value of the regulation containing aluminum solutions To 8-10, separation of solid and liquid obtains filtrate and filter residue；Filter residue calcining is obtained alumina product.
The major defect that above technology exists jointly has：Process route is complex, supplies consumption amount is larger, there is part The problem that tailings cannot be processed effectively.
The content of the invention：
Regarding to the issue above, the technical problem to be solved in the present invention is to provide a kind of by once roasting, once leaching, hydrogen Alumina extraction and excite activation four steps aluminium hydroxide and high-activity concrete additive are directly produced from Coaseries kaolin Technology, so as to the high-value-use for realizing coal series kaolin soil resource and whole waste residue zero-emission.
It is of the invention a kind of aluminium hydroxide to be produced from Coaseries kaolin and the processing step of concrete admixture is：Step One：Roasting：It is calcined under 1300-1400 DEG C of high temperature after being mixed by a certain percentage with Composite sintering agent and Coaseries kaolin miberal powder, Roasting time obtains high temperature chamotte for 2-4h, and described roasting apparatus can be in Muffle furnace, rotary kiln, tunnel cave, electric furnace Any one；
