摘要
赣州有色冶金研究所作为我国南方离子吸附型稀土的主要发现、命名和两代提取工艺的发明单位,几十年来围绕它们的开发和应用,进行了大量的研究工作,获得大批成果.但是,由于国家保密的限制,矿山生产工艺长期处于保密状态.随着项目的解密,文中将重点围绕离子型稀土矿山的开发,作出一些简明的历史性回顾.文中介绍一种全新的稀土矿种——"离子吸附型"稀土矿,并按稀土配分的特点而划分的三大类型离子矿,矿山开采的第一代工艺——"池浸工艺"(现已淘汰),第二代工艺——"原地浸出"工艺,同时概要性地介绍开采现状,涉及的工艺技术,完全拥有自主知识产权.
GNMRI, as the inventor of the two generations extraction process for the ionic adsorption rare earth in Southern China, has accomplished plenty of achievements in the past decades. Due to the confidentiality restrictions, the rare earth mining production process has long shrouded in secrecy. This paper makes a concise historical review focusing around the development of ionic rare earth mine with the current decryption of the technology. Three type of ionic rare earth, including a brand-new rare earth type, ionic adsorption rare earth, are introduced. Two generations of mining technology, pool leaching process and in-situ leaching process are discussed. The technologies involved have complete independent intellectual property rights.
