摘要
对四川冕宁稀土矿硫酸分解制取混和稀土工艺进行了研究,确定了稀土矿分解温度与时间、矿酸最佳比例、浸出温度与时间等参数,与现有硫酸法工艺比较,具有明显的节能、易于生产控制、反应时间短等特点。
A technological process o f making mixed rear earth elements form MianLin rear earthore has been studied.Some optimum parameters of the process have been obtained,such as scorchingtemperature, scorching time ,ratio between ore and acid,soak temperature and soak time,The newprocess has the advantages in shorter product time and economization in energy.
