云南文山铝业赤泥资源化利用方案设想

Resource Utilization Scheme Assumption of Red Mud in Yunnan Wenshan Aluminum Co.,Ltd.

根据铝土矿原矿成分、氧化铝生产工艺和云南省的产业发展规划,提出了文山铝业拜耳法赤泥资源化利用的一种处理方案。赤泥通过选矿工艺的优化,选出铁、钛混合精矿,经电炉熔炼生产高钛渣,为钛白粉生产提供原料。尾渣通过选矿降低了铁和碱的含量后,可以大幅拓宽赤泥在建材中的应用途径,提高用量。

A kind of treatment scheme of red mud resource utilization in Yunnan Wenshan Aluminum Co.,Ltd.is presented in this paper according to the raw ore composition of bauxite,production process of alumina and the industry planning of Yunnan province.The mixed concentrate of iron and titanium can be selected from red mud by means of beneficiation process optimization,and then the high-titanium slag can be produced by electric furnace smelting,which can be the raw material for titanium dioxide production.The tailings of red mud can be widely used in building materials after decreasing of iron and alkali content through mineral processing,which the amount of red mud can be increased.
