Terbium 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 terbium oxide. Terbium 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 extraction. Terbium oxide (Tb4O7) is used in a number of different applications, including as an alloy in metallurgy, in the production of electronic devices and in green phosphors for fluorescent lamps. The reference product amount is 1. The cut-off classification is allocatable product. The activity type is ordinary ordinary transforming activity.
