The present paper is focused on the possibilities of recovering rare metals molybdenum (Mo), uranium (U) and vanadium (V) from organic-poor metalliferous black shales on an example of Estonian argillite. For this purpose two flowsheets for processing argillite have been proposed: one is based on the separation of organic matter (OM) together with allied rare metals, and the other on the combustion of argillite in the presence of salts without prior separation of OM. For the recovery of rare
