Overview Health effects Environmental effects Sources of emissions References Description It is used in the manufacture of phosphoric acid, chlorine dioxide, ammonium chloride, fertilisers, dyes, and artificial silk and pigments for paints. It is used as a refining ore in the production of tin and tantalum, as a lab reagent, and as a metal treating agent.
In our modern economy, tantalum has become a 'technology-critical element' which is increasingly used in new technologies. This has led to a need to evaluate potential environmental impacts, which, in turn, requires knowledge of its concentration in the environment along with better understanding of the chemical processes underlying its environmental behaviour.
