四川氟碳铈矿盐酸法分离生产稀土产品工艺。起源于上世纪九十年代未。是针对四川氟碳铈的特点,由峨眉科盛首先进行研发,经几年的不断完善而今已变得成熟。该工艺的成功应用与传统的硫酸浸取,二步复盐法相比较有以下显著特点:工艺中取消硫酸、硫酸钠等原料;大幅降低了氢氧化钠及 Production of Rare Earth Products by Separation of Bastnasia Hydrochloride in Sichuan Province. Originated in the nineties of last century. Is a feature of Sichuan fluorocarbon, by Emei Ke Sheng first R & D, after several years of continuous improvement has now become a mature. The successful application of the process compared with the traditional sulfuric acid leaching, two-step double salt method has the following salient features: the process to cancel the sulfuric acid, sodium sulfate and other raw materials; substantially reduce the sodium hydroxide and
