一、一年半来的进展 稀土湿法冶金近年来在各有关科研、设计、生产单位的共同努力下,从矿石分解,单一稀土的分离,稀土化合物的制备等方面都研究出不少工艺流程。近一、两年来,又在提高工艺流程的技术先进性和经济效益两方面进行了大量的研究工作,取得新的进 First, the progress of a year and a half Rare earth hydrometallurgy in recent years, with the joint efforts of relevant scientific research, design, production units, from the ore decomposition, the separation of a single rare earth, rare earth compound preparation, etc. have developed a lot of process . In the last one or two years, a great deal of research work has been done on improving the technological advancement and economic benefits of the process and new progress has been made
