摘　　要：我国的铝土矿资源日趋枯竭,使用富含有机物的三水软铝石生产氧化铝是大势所趋。进口的铝土矿由于矿源的影响,有机物的含量较高一般在0.2%~0.4%之间,所以,进口矿源所带来的草酸盐浓度增加尤其值得重视。草酸盐的脱除受多种因素的影响,其中主要影响因素有草酸盐的溶解度、草酸盐脱除不同的工艺方法以及草酸盐的苛化率三个方面。本文将针对这些影响因素的作用规律进行分析,以达到有效地引导工艺优化,提高草酸盐的脱除效率的目的,从而为寻求进一步的草酸盐脱除处理方法奠定基础。China 's bauxite resources are drying up,the use of organic-rich three water soft alumina production is the general trend.Imported bauxite due to the impact of mineral sources,the higher the content of organic matter is generally between 0.2%~0.4 %,so the import source brought about by the increase in oxalate concentration is particularly worthy of attention.The removal of oxalate is affected by many factors,among which the main influencing factors are the solubility of oxalate,the different process methods of oxalate removal and the causticization rate of oxalate.In this paper,the action rules of these influencing factors will be analyzed to effectively guide the process optimization and improve the removal efficiency of oxalate,so as to lay a foundation for further oxalate removal treatment.
