摘要
We present a study of the extraction separation of a rare-earth group concentrate (GC) recovered from phosphogypsum waste from OAO Voskresensk Mineral Fertilizers using different extractants, followed by the preparation of neodymium oxide suitable for the fabrication of magnets. The proposed process has been tested using a pilot GC separation apparatus which includes three sequential automatic cascades of EC-10FA centrifugal extractors (Skaigrad Group).
