White Aluminum Oxide 220 Grit Wholesale Brazil

However, this method can not be used to deal with aluminium oxide grit suppliers ores with low Al Si content (Al2O3 / SiO2 is below 7-8); the process of alkali lime sintering is relatively complex, with high energy consumption, and the product cost and quality are generally not as good as Bayer method, but it can deal with high Si Al ores. In this white aluminum oxide abrasive 220 grit process, Na2CO3 can also be recovered.

After the white aluminium oxide manufacturer clinker is dissolved by alkali lime sintering method, nickel can be recovered from the circulating liquid and cement can be produced by red mud. A number of large enterprises such as Guizhou aluminum plant have successively changed the alkali lime sintering method to Bayer sintering mixed method. At present, the Al Si ratio of alkali lime sintering to deal with white fused aluminum oxide ores is generally no less than 3-3.5.


However, the brown fused alumina factory total recovery and alkali consumption of Al2O3 increased by more than 15% compared with Bayer sintering. Bayer sinter mixed process is to separate aluminum hydroxide from sodium aluminate solution by seed of alumina in bauxite, and treat the dissolved slag and ore with high silicon content by white aluminum oxide 220 grit sintering method. After the red mud in Bayer process is pretreated with alkali, Al2O3 can be recovered.


The main points of the brown fused alumina 60 grit mixed combination method adopted by Great Wall Aluminum Company are as follows: the circulating alkali solution containing a large amount of free caustic soda dissolves the alumina in bauxite, and the Al (OH) 3 is separated out from the sodium aluminate solution by seed agitation decomposition method, buy brown fused alumina so the "dissolution" of bauxite is one of the key processes.


So far, there are three kinds of enhanced dissolution technologies in industry: brown fused alumina suppliers pipeline dissolution (France, 1966). In view of the fact that diaspore is a kind of bauxite which is difficult to dissolve in our country, a reaction tank is added behind the tubular reactor. The technological process is as follows: acid alkali combination method is a method of corundum white industrial value. Dissolution from a pipeline retention tank (China, 1988).


Single tube preheating (150 ℃) - Dissolution in a autoclave (France, 1982). In view of the white fused alumina fact that most bauxite in China is diaspore type, its dissolution is far worse than that of gibbsite or diaspore type bauxite, which requires higher dissolution temperature, alkali concentration and longer dissolution time. Bayer sinter mix method is divided into series method, white aluminum oxide blast media parallel method, mix method and so on.


Acid method is to treat white aluminum oxide containing raw materials with nitric acid, sulfuric acid, hydrochloric acid and other acids to obtain the corresponding acid aqueous solution of aluminum salt. Although the acid method has been studied for more than half a century, its industrial application has not been realized because of its large investment and white fused alumina oxide mfg complex acid recovery.


The essence of thermal method is reducing white corundum smelting ore in electric furnace or blast furnace, and obtaining ferrosilicon alloy and slag containing Al2O3 at the same time. This method is still under study. All of the above are methods for preparing industrial alumina. If high-purity brown fused aluminum oxide factory with more than 99.9% Al2O3 is required, the purification method is more troublesome and costs more.
