Thorium is a naturally occurring, slightly radioactive element. It is widely distributed in nature with an average concentration of 10.5 ppm Th in the upper earth's crust. In general, thorium occurs in relatively small number in Th …
Introduction. Australia is a major world producer of titanium and zirconium minerals from mineral sand deposits. The principal heavy minerals of commercial value recovered from these deposits are ilmenite (FeTiO 3), rutile (TiO 2), and zircon (ZrSiO 4).According to Geoscience Australia, Australia has the world's largest economic resources of rutile and zircon, and the second …
