The development of alumina factory - both at home and abroad Appropriate chemical industry
alumina in the industrial production of the above application is very wide, is one of the basic materials of industrial production, domestic and foreign manufacturers have also been improving alumina production technology, for bauxite mining technology more perfect, to produce alumina step by step, also in the ascension of purity.
alumina industry in the world has one hundred years of history, France is a manufacturer of alumina earliest country, is the birthplace of the alumina industry, is early sintering was invented here. As a result of the early sintering process will cause a lot of waste of resources, then put forward the soda-lime sintering process, greatly reducing the loss of alumina and soda.
later, Austrian K. J invented the bayer process production technology, production and invest in alumina plant, for large-scale production of alumina quickly opened up a new path. This method is used to deal with the effect of low silicon bauxite is very significant, was adopted by a lot of alumina factory.
these days, many foreign manufacturers are using bayer process of alumina, followed by sintering method and combined method. For many years, the foreign alumina factory has been in the reform process, lower energy consumption, low energy consumption of large special production equipment, improve product quality.
the aluminum industry in China is developing very rapidly, the market demand for aluminium is becoming more and more big, more and more of the alumina factory set up because of this, but at present, the production of alumina is still unable to meet the needs of electrolytic aluminium factory in China, every year need to import large quantities of alumina, alumina manufacturer production varieties are more and more.
alumina manufacturers must develop its own technology in our country, strengthen the sintering process and the combined method of production process, gradually form a rational layout, advanced technology and a variety of form a complete set of complete system of aluminum industry.
