Abstract
The study on the technology of producing neodymium metal using the calciothermic reduction process is reported in this article. The process primarily involves the conversion of neodymium oxide (Nd2O3) into neodymium fluoride (NdF3) followed by the reduction of neodymium fluoride to neodymium metal using calcium as reductant. Fluorinating conditions were standardised to obtain the desired product (NdF3) free of any unwanted impurities. The calciothermic reduction of the resulting neodymium fluoride was studied in detail to establish the reduction conditions to achieve maximum yield and purity of the neodymium metal. This process obtained the neodymium metal with a purity of 99.6% before refining step.
