Russia has unique resources of rare-earth metals, which are capable to satisfy any internal needs of the country and provide access to export. A special place in the raw material base of rare-earth metals, especially because of the unique parameters of ore content takes Tomtor field (north-west of Yakutia). The paper presents an approach justifying the priority development of certain parts of the site Burannyi (Western flank), a unique fortified scarce and the most liquid and expensive rare earth element – heavy lanthanides of the yttrium group. In addition to the developed hydrometallurgical technology an alternative opinion of a full line of rare earth products from a single raw material source is offered. For the first time authors show the possibility of separation of the original ore electrofusion metal (ferroniobium) and clinker, from which rare-earth concentrate can be isolated by mechanical methods for hydrometallurgy and obtained all the REE line
