Heavy mineral sands ore deposits

As heavy mineral minerals are those referred to in the mineralogy, which have a density greater than 2.9 g / cm ³ and thus accumulate in the wash pan. The gravity concentrate, often referred to as arbitration, sits down depending on the origin very different compositions.

Typical examples are the iron and titanium minerals magnetite, hematite, limonite and ilmenite. They usually provide the bulk of the gravity concentrate and particularly the hematite is present in almost all localities. Furthermore, even cassiterite, zircon, garnets, epidote and tourmaline classic heavy minerals. But in general it depends on the geological structure of the catchment area of the water body, which mineralogical composition, the severity concentrate.
