Yttrium oxide (rare earth oxides production - from rare earth carbonate concentrate)

The activity generating the emissions is rare earth oxides production, from rare earth carbonate concentrate. The reference product is yttrium oxide. Yttrium is a transition metal that, due its strong similarities, is always found together with lanthranide elements in rare earth minerals. Yttrium is produced through all common rare earth oxide production routes, including carbonate-containing bastnaesite ores, monzonite ores and ion absportion clays. Almost all yttrium oxide (Y2O3) is produced in China. The substance has a number of different applications, including use in fillers, putties, plasters and modelling clay, as well as various medical applications. The reference product amount is 1. The cut-off classification is allocatable product. The activity type is ordinary ordinary transforming activity.
