Rhenium – a valuable and rare element

Limited resources make rhenium one of the rarest metals in the Earth''s crust. Only certain ores contain traces of rhenium and its extraction takes place exclusively as a by-product of the processing of these ores. This makes it vitally important to recover this rare element by recycling used materials containing rhenium.
