Recovery of high purity Scandinavia

摘要

It provides a Scandinavian recovery method that can easily and effectively recover Scandinavia from high purity nickel oxide ores. This method of recovering Scandinavia involves transferring a solution containing Scandinavia through an ion exchange resin. 2. Solvent extraction was carried out with the fiber spray of ion exchange resin, and the residual extract and extractant were separated after extraction. Then an Oxalization process was carried out in the residual extract to obtain a precipitate from Scandinavian oxalic acid.The precipitation is calcified to obtain Scandinavian oxides, which is characterized by the use of extractants as solvent extractants; LT; / P GT;
