[China Aluminum Network] At present, the supply of bauxite resources in China is becoming increasingly scarce. It is urgent to adopt effective methods to increase the utilization of bauxite resources. Looking back over decades of production practices, the need to develop homogenized new technologies is beyond doubt. The use of scientific technology and advanced equipment, make full use of a large number of low-grade ore and mixed grade ore and crushing ore to prepare a series of alumina-based homogenized materials with excellent properties, with emphasis on mullite homogenizing materials and qualified enterprises. Flotation and purification, or the use of electrofusion methods to reduce raw material impurities, or add a small amount of additives to improve the microstructure of the material, improve material properties, so that China's bauxite resource utilization from the current 20% to more than 80%, Achieved sustainable development. The development of homogenized series of products can effectively promote the upgrading of bauxite raw material quality, performance and added value. It can also realize the large-scale mechanized mining of bauxite mines, and form a complete set of modern production systems adapted to the characteristics of resources. Therefore, the development Bauxite homogenization material has important practical significance and broad market prospects.
The official research work of China's bauxite homogenization materials began in the Yangquan project in the 1970s. The "8th Five-Year Plan" was included in the research project, and there has been a relatively solid foundation for research and production. In recent years, laboratory data of some scholars have proved that bauxite-based mullite homogeneous material has excellent high-temperature mechanical properties, such as high temperature fracture strength, when corundum/mullite 75:25 or 25:75 is better, high temperature creep The ranking order of performance is grade II, such as Al, Al, and Al etc. It is not that the Al2O3 content in sintered high-alumina bauxite is better, which further supports theoretically the development of bauxite in China for many years.
