摘要
岩溶堆积型铝土矿是国内新类型的铝土矿床 ,矿床的工业指标是在地质勘探时期制定的 ,未经生产进行验证。文章分析了堆积型铝土矿的地质特点和拜耳法生产氧化铝技术工艺条件对矿石质量的要求 ,结合近几年矿山采、选资料和生产成本 ,对工业指标提出了一些商榷和探讨意见。
Karst stack type bauxite deposit is a new type bauxite deposit in China, and its industrial index is formulated during geologic exploration without being checked by production run. This article analyzes the geologic specialities of karst stack type bauxite and the requirement for bauxite quality according to technological condition in Bayer process , gives some opinions on exchanging and exploring industrial index which connected with mining, dressing document and production cost of bauxite mine during recent years.
