我国铝土矿资源比较丰富,目前已有二十多个省、市、自治区探明了铝土矿储量,但主要集中在山西、河南、贵州和广西等省区,其保有储量占全国的80％以上,形成了我国铝土矿的重要基地。现有铝土矿资源除能满足生产矿山的生产能力外,还有相当数量的矿区可供近期开发建设。我国铝土矿床主要有三种类型:沉积型、堆积型和红土型铝土矿床。而沉积型产于碳酸盐岩侵蚀面上的大、中型矿床,工业
At present, more than 20 provinces, municipalities and autonomous regions have proved their bauxite reserves, but they are mainly concentrated in the provinces and autonomous regions such as Shanxi, Henan, Guizhou and Guangxi, and their reserves have accounted for 80% of the national total %, Forming an important base of bauxite in our country. In addition to the existing bauxite resources to meet the production capacity of production mines, there are a considerable number of mining areas for the recent development and construction. There are mainly three types of bauxite deposits in China: sedimentary, accumulation and laterite-type bauxite deposits. Sedimentary production in carbonate erosion surface of large and medium-sized deposits, industry
