Thulium 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 thulium oxide. Thulium is a lanthanide, a rare earth element, that is predominatly obtained from the ion adsorption clays of southern China - representing approximately 98% of world production - as a by-product of yttrium and gadolinium extraction. Thulium oxide (Tm2O3) is used in a number of different applications, most prominently as an active laser medium material and in x-ray devices. The reference product amount is 1. The cut-off classification is allocatable product. The activity type is ordinary ordinary transforming activity.
