| Abstract: | The project of industrial scale test base was sanctioned by the state Planning Com- mission of China. Its purpose is to develop new technology and equipment in industrial scale for producing rare earths. For feed material containing middle yttrium and rich lanthanum,the process flowsheet of two extractants for producing fluorescent grade yttrium oxide and the reductive ex- traction flowsheet for getting high purity europium have been developed. The annular centrifugal extractors and reciprocating sieve plate column were selected as main equipments for solvent ex- traction and they were proved efficient.The line-in analysis and simple back control system has been used in the industrial scale test in order to realile automatic control. |
