Zirconium minerals with industrial value consist of baddeleyite (ZrO 2) and zircon (ZrSiO 4), among which zircon is the primary raw mineral material of zirconium smelting.Hafnium oxide (HfO 2) and radioactive materials are in various zircons.Zirconite, also called zircon, is a general term for zirconium silicate minerals.
