摘要
试验采用氟化铵与石灰石粉、石灰乳反应制取氟化钙,研究了反应温度、物料浓度、物料过量系数等各主要参数变化对氟化钙结晶、过滤速度、氟收率及其含量的影响,摸索出最优反应条件。
The ammonium fluoride was used during the experiment together with the limestone powder and lime milk to extract calcium fluoride through reaction.The reaction temperature,material concentration and excess coef-ficient were analyzed to find out their impact on the crystallization of calcium fluoride,filtering speed,fluoride yield and content.The optimized reaction conditions was explored.
