Dissolution of the use of technology to strengthen Bayer alumina plant and construction of small


Zhengzhou Light Metal Research Institute pre-production experience, expected first year of production equipment operation rate can reach 50 to 70, the second year of up to 85 or more. 4 pre-production profits and taxes of 2O, the high cost of the unit consumption indicators analysis showed that the production cost can be significantly reduced. Pilot production facilities operating in 1989, low, coupled with the expansion of electricity, resulting in higher power consumption per unit of product through the plant capacity and operation of play against the capacity of accounting that normal production, this can reduce the cost of 61.94 yuan / tI1989 purchase price in caustic soda plant of 3,600 yuan / t, the current caustic soda prices have fallen, this can reduce the cost of production l36.59 yuan / t,uggs online bestellen, oil change coal-fired molten salt furnace stove, the fuel from oil to coal, this Items can reduce the cost of 130.12 yuan / t this way, the cost per ton of aluminum hydroxide (excluding equipment depreciation and taxes) can be reduced to less than $ 1O00. 5.1989, the actual output rate of aluminum hydroxide,uggs nederland, a product 64, the output value 220 million yuan, cuts profits nearly 6O million Based on projections, when the equipment operation rate to 70%, the annual output of up to 74O million yuan, profits and taxes 170 million. When the device is running at full capacity,ed hardy suomessa, annual output value of more than ten million yuan, profits and taxes of up to 2.5 million. Fifth,mulberry oslo, the building of small alumina plant feasibility study to promote technological progress of China's alumina, alumina plant construction to promote the health of a small development,uggs nederland, Zhengzhou Light Metal Research Institute in December 1989, the annual output of 10,000 t of alumina scale small plant for the demonstration program, technical and economic research, from April to June 1990 in respect of a proposed annual output to 15,000 t of aluminum hydroxide plant for a feasibility study, we have achieved good results. VI Conclusion. Zhengzhou Light Metal Research Institute through the pilot plant for alumina production practices and annual 1.57yt trial of aluminum hydroxide or l million tons of alumina a small-scale plant study is not difficult to see that a stay can strengthen the use of pipeline technology and construction of small oxide dissolution aluminum, technically advanced,ed hardy lippis, reliable, economically profitable, low investment, quick, suitable for local factories. However, due to various constraints, for the construction of small alumina plant, still holds a positive attitude and secure. Bayer to use Al-Si high bauxite. The higher grade ore,ralph lauren outlet, the better the economy. Therefore,ed hardy vaatteet, the construction of such plants should pay attention to rational use of bauxite resources. China's high-grade bauxite in some places, but the storage is not dispersed, using this method to deal with such ores and construction of small alumina plant is suitable for the production of refractory materials I used in high-grade bauxite, and some only for potassium, sodium and iron and high granularity inappropriate or abandoned without the cooperation, using this method to deal with such a small drop of mineral alumina plant construction is appropriate, in our existing large alumina plant,mulberry outlet, the use of this technology by 3 to build an annual output of 50,000 t of alumina sub-process is appropriate. This is a better and more economical production methods. Zhengzhou Light Metal Research Institute of alumina in the pilot plant has been improved in the side of the production side, to make the pipe a stay perfect technology can enhance the dissolution, we believe that this country - for processing type of diaspore bauxite distinctive stripping technology application, will make the face of China's alumina industry - new, to promote the development of China's aluminum industry. (Continued from page 19) security regulations and requirements of regulations, but also takes into account the increasingly stringent requirements, therefore, boast a long time after the need for transformation within. Canada's active participation in international Magnesium Magnesium Association, the National Institute of magnesium technology organization to develop magnesium market development. Full account of the layout of the plant's long-term planning vision for the expansion project sites and facilities needed to allow sufficient room and convenient conditions. The second generation magnesium Act - Mage Kan Magnesium is an advanced new method of refining magnesium method, has obvious advantages, especially in energy efficiency. Electrolysis of magnesium under the old process the total energy consumption is about 16500kW. h / t, but with Mage Kan production of magnesium can reduce the consumption of about lO about is 14850kW. h / t so. Proposed construction of new China in magnesite as raw material to when the introduction of Mage Kan Magnesium Magnesium method patents. (WANG Zhu-tang) east and west Germany, the two co-Carbide plant,mulberry norge, according to technical and commercial cooperation. Agreement include: ink Er Bolun permitted by this East Germany with 1,500 employees, the largest carbide plant from Krupp Boweidiya plant more advanced technology. Wei Diya plant hire ~ 199, oo people, in carbide production is a world leader. Meanwhile, the plant can be used by Mexican Er Bolun Krupp Boweidiya vast market to sell their brands to. Harth ~ cutting tools. (Liu) - ■ ■ present
