山东省铝土矿资源综合利用的探讨

Utilization of Bauxite Resources in Shandong Province

山东淄博铝土矿是全国发现最早的铝土矿矿区,经过四十余年的开采,山东铝土矿尚保有地质储量4476.5万吨。现有矿石铝硅比低而含硫高,资源零星分散,开采条件差,而不能利用。山东铝业公司氧化铝生产矿石供应需要高品位矿石,利用山东省低品位矿石进行选矿,是经济供矿和充分利用资源的重要途径。

Zibo Bauxite Mine, Shandong is one of the earliest bauxite field discovered in China. After 40 years exploitation, it remains the reserve of 44765kt. But the remains is difficult to utilize due to its low mass ratio of alumina to silica, high content of sulphide, divergent resources and poor mining conditions. To meet the need for high grade ores of Shandong Aluminum Corporation, processing of the local low grade bauxite is an economic way for making the full use of the resources.
