    Heavy Mineral Sands Ore Deposits Grade And Tonnage

    The grade of a typical heavy mineral sand ore deposit is usually low. Within the 21st century, the lowest cut-off grades of heavy minerals, as a total heavy mineral concentrate from the bulk sand, in most ore deposits of this type is around 1 heavy minerals, although several are higher grade.. Of this total heavy mineral concentrate THM, the components are typically

    Mineral sand deposits are formed from the erosion and weathering of pre-existing igneous rocks such as granite, pegmatite and basalt. Over 60 to 200 million years the combinations of wind and water from ancient rivers and seas have leached the minerals from their past rocks and concentrated them into beach and dune deposits.
