Ilmenite is a primary ore of Titanium and a key source for Titanium oxide which is an important pigment, whiting, and polishing abrasive. Ilmenite is a black mineral with a submetallic to metallic luster. Titanium alloys are used for making high-performance parts and tools like aircraft parts, artificial joints for humans, and sporting equipment such as bicycle frames. Ilmenite is also used to produce synthetic rutile. Titanium dioxide pigments roduce a white color and brightness in paint, paper, adhesives, plastics, toothpaste, and even food. Titanium oxide abrasives are used in many other industries.
Rutile is the most abundant natural form of Titanium oxide mineral. Its color ranges from red to reddish brown, black, yellow to gold. The primary uses of rutile and titanium oxide made from rutile are: manufacturing titanium oxide pigments, manufacturing refractory ceramics, and production of titanium metal. Titanium oxide gives these products a color that is resistant to fading. Titanium oxide is also nontoxic and chemically stable. Those properties allow it to be used as a pigment in food, cosmetics, pharmaceuticals, and many consumer products such as toothpaste.
Zircon is the natural form of Zirconium Silicate. Zircon is used to produce zirconium metal and zirconium dioxide. Zircon sand has a low expansion coefficient and is very stable at high temperatures. It is used as a refractory material in many foundry and casting applications. One of its most common uses is in the production of ceramics. Zirconium is used in a variety of metal products that require a resistance to heat and corrosion. It is used to make high-performance alloys, specialty steel, lamp filaments, explosive primers, computer equipment and many electronics components.
Almandine Garnet is the heaviest and hardest of all abrasives in this world. Garnet is a relatively hard mineral with a hardness that ranges between 6.5 and 7.5 on the Mohs scale. It could withstand in highest cutting speed and maintain low dust levels, with its crystalline shape giving a fast cutting action and longer life span. Garnet has served primarily for its many dimension applications i.e. blast media, water jet cutting, coated abrasives, surface preparation, grinding media, water filtration and so on.
Sillimanite, also called Fibrolite, is a colorless, or white glassy silicate mineral frequently found infibrous aggregates. It occurs in high-temperature regionally metamorphosed clay-rich rocks. It occurs with andalusite, kyanite, potassium feldspar, almandine, cordierite, biotite and quartz in schist, gneiss, hornfels and also rarely in pegmatites. It is an index mineral indicating high temperature but variable pressure. Sillimanite is used in the manufacture of high alumina refractories or 55-60% alumina bricks.
