中文摘要: 研究了反应条件对稀土精矿络合浸出废液合成的冰晶石中硅浸出的影响。结果表明,在盐酸浓度4.0 mol/L、氯化铝浓度1.5 mol/L、反应时间120 min、液固比30︰1、搅拌速度300 r/min和85 ℃条件下,硅的浸出率达到了35%以上,冰晶石中的硅确实是络合浸出过程进入溶液中的。
Abstract:Effects of reaction conditions on leaching of silicon in cryolite synthesized from leaching waste solution of complexation extraction of rare earth concentrates were investigated. The results show that silicon leaching rate is 35% above under the optimum conditions including hydrochloric acid concentration of 4 mol/L, aluminum chloride concentration of 1.5 mol/L, reaction time of 120 min, L/S=30︰1, stirring speed of 300 r/min, and temperature of 85 ℃. Silicon in cryolite really enters into solution during complexation extraction of rare earth concentrates.
