Mineral sands are within a class of ore deposits that contain heavy minerals such as ilmenite zircon leucoxene and rutile The most important naturally occurring minerals that are mined to produce titanium dioxide TiO 2 feedstock are ilmenite leucoxene and minerals are either used as feedstock in their natural form or in an upgraded form such as synthetic rutile and titania

The term mineral sands refers to concentrations of minerals commonly found in sand deposits The titanium dioxide ores include rutile leucoxene chloride and sulphate ilmenite Ilmenite in some cases is able to be upgraded to higher grade titanium dioxide feedstocks including synthetic rutile and slag The global TiO 2 pigment market

origin of mineral sands deposits Home Products Sandstone Sedimentary Rock Pictures Definition More What is Sandstone Sandstone is a sedimentary rock composed of sand size grains of mineral rock or organic material It also contains a cementing material that binds the sand grains together and may contain a matrix of silt or clay size particles that occupy the spaces between the sand grains

Such sand deposits are said to be mature because other rock forming minerals are already broken down by the weathering process leaving only the super resistant quartz as a residue Silica sand is a mineral resource It is mined mostly for glass making Another major use of sand is a concrete production but that does not need sand to be as pure
