Kyanite Aluminium Silicate (KAlSi3O8). SG of 3.5.
Leucoxene The limiting case of Altered Ilmenite wherein some or all of the Ferrous Oxide has been weathered out in varying degrees and converted to Ferric Oxide and then naturally leached from the mineral grain causing upgrading of the TiO2 content . SG varies from 3.6 -- 4.3. The TiO2 content varies between 65 and 92%.
Magnetite Ferrous Oxide (Fe3O4). Ferromagnetic with SG of 5.2.

Oleophilic Attracted to oil by virtue of their surface chemical properties.
ppm Parts per million

Tailings Valueless detritus material from a separation or concentration process.
Synthetic Rutile A product from a process whereby ilmenite is converted in a pyrometallurgical (roasting) process to convert the titanium component into the insoluble rutile form, while conditioning the iron component for leaching. It is then rapidly leached at atmospheric pressure in acid to remove the iron, leaving a network of rutile crystals in the former ilmenite grain. This "synthetic" rutile is then washed, filtered and heated (calcined) to make the final saleable product. The final product TiO2 content can vary from 91% - 96%.

Titanium The ninth most abundant element in the earth's crust and occurs naturally as TiO2 in a number of minerals, those of greatest commercial importance being Ilmenite, Leucoxene and Rutile.

Approximately 95% of titanium is consumed in the form of titanium dioxide (TiO2), an intensely white permanent pigment with good covering power in paints, paper, toothpaste, and plastics. Paints made with titanium dioxide are excellent reflectors of infrared radiation and are therefore used extensively by astronomers and in exterior paints. It is also used in cement, in gemstones, and as a strengthening filler in paper.

Because of its very high tensile strength (even at high temperatures), light weight (43% lighter than steel), extraordinary corrosion resistance, and ability to withstand extreme temperatures, titanium alloys are principally used in aircraft, armour plating, naval ships, spacecraft and missiles. It is used in steel alloys to reduce grain size and as a deoxidiser but in stainless steel it is employed to reduce carbon content. Titanium is often alloyed with aluminium (to refine grain size), vanadium, copper (to harden), iron, manganese, molybdenum and with other metals.

Its vanadium alloy is used to make the outer skin of aircraft, to make fire walls, landing gear, and hydraulic tubing. A typical commercial jet airplane contains 320 to 1130 kg of titanium. Use of titanium in consumer products such as golf clubs, bicycles, laboratory equipment, wedding bands, and laptop computers is becoming more common.
Titanium Dioxide White powder used as pigment or filler for its high covering power, durability and stability in ultra-violet light and opacity in coatings, plastics, and paper.
