中国长城铝业公司、北京矿冶研究总院、中南工业大学、郑州轻金属研究院、沈阳铝镁设计研究院和中国有色金属工业技术交流中心六家单位,经过三年多的共同努力,把选矿工艺与拜尔法工艺成功地进行了对接,创造了“选矿——拜尔法”生产氧化铝新工艺。这是我国氧化铝生产领域的一次重大技术革命。 110年前,奥地利化学家拜尔发明了拜尔法生产氧化铝工艺。拜尔法生产氧化铝工艺简单、综合能耗和产品成本比较低。目前全世界90％以上的氧化铝仍是用这种方法生产的。但拜尔法不联理铝硅比低于10的矿石。据地勘资料,我国铝矿资源仅次于澳大利亚、
China Great Wall Aluminum Corporation, Beijing Mining and Metallurgy Research Institute, Central South University of Technology, Zhengzhou Institute of Light Metals, Shenyang Institute of Aluminum and magnesium and China Nonferrous Metals Industry Technology Exchange Center six units, after more than three years of joint efforts to the beneficiation Process and Bayer process successfully conducted a docking, creating a “beneficiation - Bayer process” to produce alumina new technology. This is a major technological revolution in the field of alumina production in our country. 110 years ago, the Austrian chemist Bayer invented the Bayer process for the production of alumina. Bayer process alumina production is simple, comprehensive energy consumption and product cost is relatively low. At present, more than 90% of the world’s alumina is still produced by this method. However, Bayer method is not associated Al-Si than 10 ore. According to geological survey data, China’s aluminum resources second only to Australia,
