赣州有色冶金研究所与南昌曙光稀土材料厂合作,采用串级萃取理论进行工艺参数计算,并将计算参数一步放大到工业设计。省去了通常的试验研究,可节省大量费用,加快工程进度。该方法成功可靠,整个工艺采用钕钐分组,接二个“三出口”工艺,一次进料直接得二个单一产品和若干个富集物产品,属国内首创。技术经济指标,均超过设计指标。稀土收率达96％。
Ganzhou Institute of Nonferrous Metals and Nanchang Shuguang rare earth materials plant cooperation, the use of tandem extraction theory for the calculation of process parameters, and calculation parameters will be expanded to one step industrial design. Save the usual experimental research, can save a lot of costs and speed up the progress of the project. The method is successful and reliable, the whole process using neodymium samarium grouping, then two “three exit” process, a feed directly to two single products and a number of enrichment products, is a national initiative. Technical and economic indicators, are more than design indicators. Rare earth yield of 96%.
