Method for resource utilization pretreatment of sulfuric acid process titanium dioxide byproduct titanium gypsum
The invention discloses a method for resource utilization pretreatment of sulfate process titanium dioxide byproduct titanium gypsum. The method comprises the following steps: material selection: selecting a certain amount of sulfate process titanium dioxide byproduct titanium gypsum; rinsing and impurity removal: rinsing and impurity removal are performed on the selected titanium gypsum; drying: heating and drying the titanium gypsum; and screening and impurity removal: carrying out screening and impurity removal on the dried titanium gypsum. According to the pretreatment method for resource utilization of the sulfate process titanium dioxide by-product titanium gypsum, in the pretreatment process of the sulfate process titanium dioxide by-product titanium gypsum, the dissolution speed of FeSO4 is the highest by controlling the dissolution temperature of FeSO4 at 90 DEG C, and meanwhile, the generation speeds of CaSO4, Fe2O3 and Al2O3 are the highest by setting the generation temperatures of CaSO4, Fe2O3 and Al2O3 at 165 DEG C, so that the utilization rate of the sulfate process titanium dioxide by-product titanium gypsum is increased, and the utilization rate of the sulfate process titanium dioxide by-product titanium gypsum is increased. Therefore, the pretreatment speed of the sulfuric acid process titanium dioxide byproduct titanium gypsum is greatly improved, the production efficiency is improved, and the production cost is reduced.
本发明公开了一种硫酸法钛白副产钛石膏资源化利用预处理的方法，包括以下步骤：取材：选取一定量的硫酸法钛白副产钛石膏；过水除杂：对选取的钛石膏进行过水除杂；干燥：对钛石膏进行加热烘干；筛选除杂：对干燥后的钛石膏进行筛选除杂。本发明所述的一种硫酸法钛白副产钛石膏资源化利用预处理的方法，本发明在对硫酸法钛白副产钛石膏进行预处理的过程中，通过将FeSO4的溶解温度控制在90℃，使得FeSO4的溶解速度最快，同时通过将CaSO4、Fe2O3、Al2O3生成温度设置在165℃，使得CaSO4、Fe2O3、Al2O3的生成速度最快，这样极大地提升了硫酸法钛白副产钛石膏预处理的速度，增加了生产效率，降低了生产成本。
