Abstract
The aim of the present study is to investigate the extraction, separation and recovery of the indivisible metals of dysprosium and neodymium from permanent magnets scrap leach liquor solutions with meaningful recovery. The present experimental development focused on dysprosium separation from neodymium and recovery by suitable mineral acids. Fundamental studies of the effect of time, pH and extractant concentration on the metal separation were conducted followed by proposal of a mechanism for extraction. Process development included generation of McCabe-Thiele diagrams and counter current extraction (CCE) studies. After loaded organic generation from the CCE process, this was followed by scrubbing studies as well final recovery of dysprosium.
