This requires to develop alumina industry

This requires to develop alumina industry. Since 1954, Shandong Aluminum production, there Zhengzhou Aluminum Plant, Guizhou Aluminum Plant, Shanxi Aluminum Plant put into operation. Alumina production capacity of 1.2 million tons or more. In order  activated zeolite powders  to meet the needs of the development of the aluminum industry are planning to build a peaceful fruit Zhongzhou Aluminum smelter;and expansion of old plants need to gradually form an alumina base molecular sieve drying in Central China, Northwest, Southwest aluminum base for a more reasonable layout. Alumina production and species will continue to increase. According to the characteristics and production status of bauxite resources, the total recovery of  molecular sieves drying  alumina and alkali consumption compared with similar foreign factories, reached the advanced level. And most economical way to recover from the mother liquor circulation gallium; successful use of the alumina production waste - red mud production of cement, from the surface to improve the overall efficiency of alumina production. At present, the main technical development direction of China's aluminum industry is: continue to develop baked knot and joint production process, using indirect heat strengthened dissolution, fluidized roasting and other new technologies and high equipment.
