我国铝土矿资源非常丰富,但矿石多为一水硬铝石—高岭石型,其特点是高铝、商硅、低铁,矿石铝硅比多为4～6。为了提高该类型矿石质量和扩大铝原料,从1970年开始,冶金部沈阳铝镁设计院先后与东北工学院、山西铝厂、中条山有色金属公司、郑州铝厂轻金属研究所、郑州铝厂小关矿等单位合作,对山东沣水、本溪小市、山西孝义、河南小关等矿进行了
China’s bauxite resources are very rich, but most of the ore is a diaspore - kaolinite type, which is characterized by high-aluminum, silicon, iron, ore, aluminum and silicon ratio of mostly 4 to 6. In order to improve the quality of this type of ore and expand the raw materials of aluminum, from the beginning of 1970, Shenyang Institute of Aluminum and Magnesium, Metallurgical Department met successively with Northeast Institute of Technology, Shanxi Aluminum Plant, Zhongtiaoshan Nonferrous Metals Company, Zhengzhou Aluminum Institute of Light Metals, Zhengzhou Aluminum Plant Small customs and other units of mine cooperation, Shandong Shanshui, Benxi small market, Shanxi Xiaoyi, Henan Xiao Guan and other mines carried out
