Coke Solid reductant produced from the distillation of crude oil or the devolatilisation of coal. Used as a source of carbon reductant in metallurgical operations such as the chloride process
Chloride Pigment Process Industrial process for transforming +62% TiO2 minerals, +80% TiO2 slags and +90% TiO2 synthetic rutile in a medium of hot chlorine gas and coke, to form Titanium Tetrachloride("tickle"), used in the manufacture of Titanium Dioxide pigments and titanium metal.
Deposit A mineralized body which has been delineated and found to contain sufficient mineral grade and commercial value to justify further exploration or development work. A deposit does not become a reserve until certain legal, technical and economic factors have been addressed and resolved.
Dry Mill Plant where dry separation processes are employed for the separation of valuable heavy minerals. Also referred to as a Mineral Separation Plant (MSP).
Estuarine Deposits Alluvial Deposits which originated in an estuary.
Foundry An establishment where metal is melted and poured into moulds. The moulds themselves must not melt at the molten metal temperature. Highly thermally resistant materials such as Zircon are used to line these moulds.
Froth Treatment Plant See "Centrifuge Plant".

Garnet A family of minerals conforming to a specific chemical composition containing silicate, (Ca, Mg, Mn, Fe, Al, Cr).SiO4. They are very hard and used as an abrasive or sand blasting medium. SG varies between 3.4 and 4.3.
Gravity Spiral Concentrator A vertically oriented multi-cycle helical sluice, at the top of which a sand slurry is introduced. Separates solids in the slurry based on their SG and size grading using centrifugal force and hydrodynamic transport.
Heavy Minerals Minerals found in sands having SG of not less than 2.8, including Zircon, the titanium-bearing minerals Rutile, Anatase, Ilmenite, and Leucoxene, as well as Garnets, Tourmalines, Kyanite, Siderite, Pyrite, Magnetite, and others.
Ilmenite Iron Titanium Trioxide (FeTiO3 or FeO.TiO2). SG of 4.7. The TiO2 content naturally varies from 35% to 65%. The most abundant titanium mineral.
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.
Mineral Sands This term normally refers to concentrations of heavy minerals in an alluvial (old beach or river system) environment. In some cases also referred to as "beach sands".
Mineral Suite The make-up or assemblage of the various minerals present in an ore body or process stream.
Oleophilic Attracted to oil by virtue of their surface chemical properties.
ppm Parts per million
Pseudorutile Originally referred to a arizonite, is formed by the alteration of ilmenite and contains 60% - 65% TiO2
Pyrite Iron Sulphide (FeS2) or "Fool's Gold". SG of 5.1.
Quartz Silicon Dioxide (SiO2) or Silica. SG of 2.6.
Refractory Material that has a high melting point, such as Zircon.
Rutile A certain crystallographic form of Titanium Dioxide, with SG of 4.2. The TiO2 content typically varies from 94% - 96%.
SG Specific gravity of a mineral relative to water, which is 1.
Siderite Iron Carbonate (FeCO3). SG of 3.9.
Silicates Silicon Dioxide (Quartz) and other minerals largely consisting of silicon and oxygen, often erroneously used to refer to those minerals with SG less than 2.8.
Slimes Valueless undersize material (or fines) in a sand mixture, both mineral and organic, including clay. Typically defined as particles smaller than 45m.
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%.
THM Total Heavy Mineral fraction by mass, as derived from the sinks fraction of a heavy liquid separation test procedure, using Tetra-bromo-ethane (TBE) with a density of 2.95 or Bromoform with a density of 2.85.
TiO2 Units Amount of Titanium Dioxide contained in a mineral assemblage, used for making direct comparison of the valuable fraction of different ores or mixtures.
TiO2 Slag The product whereby ilmenite is smelted in an electrical submerged arc furnace at plus 1600C. Pig iron is also tapped as a by-product. The slag can typically have a TiO2 content of 80% -92%.
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.
