Scientists have recently developed new processes for improving the alumina purity of the bauxite found in Shanxi, Henan and elsewhere. This paper describes the processing steps in detail to show that the resulting alumina materials achieve improved chemical and physical properties. The paper will show that this is done at lower energy and cost. Homogenization permits the use of conventional raw bauxite or alternately a lower grade, lower cost bauxite as the feed stock for increased utilization of previously marginal resources. The homogenized, higher purity material shows improved performance when used as an ingredient in alumina-silica refractories and other ceramic applications. Case histories comparing the performance of this new refractory raw material show that Homogenized Bauxite can be successfully substituted for other less competitive materials including brown fused alumina. The paper concludes with a projection of product development planned for continuous improvement.
