    Heavy mineral sands ore deposits

    Heavy mineral sands are a class of ore deposit which is an important source of zirconium, titanium, thorium, tungsten, rareearth elements, the industrial minerals diamond, sapphire, garnet, and occasionally precious metals or gemstones.. Heavy mineral sands are placer deposits formed most usually in beach environments by concentration due to the specific gravity of the mineral grains.

    Recovery of scandium, yttrium and lanthanides from zircon sand

    In contrast to many other industrial minerals, zircon sand is a rather pure mineral. The total impurity content is only about 1% (zircon sand is about 99% zirconia, hafnia, and silica). Of the impurities present, most have volatile chlorides and pass into the vapor stream with the zirconiumhafnium tetrachloride and the silicontetrachloride.
