摘要
研究了硫酸法钛白粉酸解过程中,酸矿比、反应酸浓度、引发温度对固相物溶解率的影响.结果表明:酸矿比1.50～1.70范围内对固相物溶解率影响较小;反应酸质量分数从81％～89％显著影响升温速率,溶解率随之下降,结合钛的浸取率考虑最优反应酸浓度为83％;引发温度对固相物溶解率影响显著,145℃为最佳引发温度.研究为优化硫酸法钛白粉生产工艺,提高钛白粉产能提供了理论依据.
Abstract
The effects of acid mineral ratio,reaction acid concentration,and initiation temperature on the dissolution rate of solid phase in the acid hydrolysis process of titanium dioxide by sulfuric acid method were studied.The results showed that the acid mineral ratio had little effect on the solubility of solid phase within the range of 1.50～1.70.The mass fraction of reactive acid significantly affects the heating rate from 81％to 89％,and the dissolution rate decreases accordingly.Considering the leaching rate of titanium,the optimal concentration of reactive acid is 83％.The triggering temperature has a significant impact on the dissolution rate of solid phase,with 145 ℃ being the optimal triggering temperature.The study provides a theoretical basis for optimizing the production process of titanium dioxide by sulfuric acid method and improving the production capacity of titanium dioxide.
