摘要
以A稀土矿为原料,选取不同粒级精矿,在不同矿酸比和焙烧温度下,按照要求进行多次静态硫酸焙烧试验,根据试验数据综合分析选择稀土的最佳条件,提高稀土精矿的分解率和回收率.
In the experiment,the A rare-earth mineral is selected as raw material. Different mesh grain concentrates,mineral acid ratio and calcination temperature are selected,multiple static sulfuric acid roasting experiments have been done in accordance with the requirements,the optimum condition is selected according to comprehensive analysis of the experimental data,in order that the rate of decomposition and recovery of rare earth concentrate are improved.
