Tiwest Joint Venture
The Tiwest Joint Venture was a joint venture between Tronox Western Australia Pty Ltd and subsidiaries of Exxaro Australia Sands Pty Ltd. The Tiwest Joint Venture was a mining and processing company, established in 1988, to extract ilmenite, rutile, leucoxene and zircon from a mineral sands deposit at Cooljarloo, 14 km north of Cataby, Western Australia. As of June 2012, the joint venture was formally dissolved, when Tronox acquired the mineral-sands-related divisions of Exxaro outrigh Tiwest's corporate office (sales/marketing/accounting/administration/IT/etc) was located in Bentley, five minutes drive south of the Perth, Western Australia, Perth central business district. During the joint-venture phase of operations, from 1988 through 2012, heavy mineral concentrate was trucked from Cooljarloo, 1 hour and 15 minutes south to the Chandala mineral sands processing plant, near Muchea, 70 km north of Perth, Western Australia, Perth. The concentrate was then separ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mining
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit. The exploitation of these deposits for raw material is based on the economic viability of investing in the equipment, labor, and energy required to extract, refine and transport the materials found at the mine to manufacturers who can use the material. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desire ...

Perth, Western Australia
Perth is the capital and largest city of the Australian state of Western Australia. It is the fourth most populous city in Australia and Oceania, with a population of 2.1 million (80% of the state) living in Greater Perth in 2020. Perth is part of the South West Land Division of Western Australia, with most of the metropolitan area on the Swan Coastal Plain between the Indian Ocean and the Darling Scarp.

Titanium Dioxide
Titanium dioxide, also known as titanium(IV) oxide or titania , is the inorganic compound with the chemical formula . When used as a pigment, it is called titanium white, Pigment White 6 (PW6), or CI 77891. It is a white solid that is insoluble to water, although mineral forms can appear black. As a pigment, it has a wide range of applications, including paint, sunscreen, and food coloring. When used as a food coloring, it has E number E171. World production in 2014 exceeded 9 million tonnes. It has been estimated that titanium dioxide is used in two-thirds of all pigments, and pigments based on the oxide have been valued at a price of $13.2 billion. Structure In all three of its main dioxides, titanium exhibits octahedral geometry, being bonded to six oxide anions. The oxides in turn are bonded to three Ti centers. The overall crystal structure of rutile is tetragonal in symmetry whereas anatase and brookite are orthorhombic. The oxygen substructures are all slight dist ...

Kwinana Beach, Western Australia
Kwinana Beach is an outer southwestern suburb of Perth, Western Australia, located within the City of Kwinana. It is one of the traditional industrial suburbs in the Perth metropolitan region. History Kwinana is originally a local indigenous Australian word meaning either "young woman" or "pretty maiden". The ship was wrecked on Cockburn Sound in 1922, and blown on to the beach. The nearby area acquired the name Kwinana Beach when the local postmistress, Clara Wells, immediately started labeling the mail sacks "Kwinana Wreck", to distinguish the settlement there from Rockingham, to the south. Kwinana Beach was officially adopted as a township in 1937. With the new industrial developments at Kwinana Beach in the 1950s, led by BP's Kwinana Refinery, a large new workers settlement – Kwinana Townsite – was purpose-built slightly inland. Other industries quickly followed – Alcoa, CSBP, CBH, Coogee Chemicals, and others. The original village at Kwinana Beach was ...

As-is
As is, when employed as a term with legal effect, is used to disclaim some implied warranties for an item being sold. Certain types of implied warranties must be specifically disclaimed, such as the implied warranty of title. "As is" denotes that the seller is selling, and the buyer is buying an item in whatever condition it presently exists, and that the buyer is accepting the item "with all faults", whether or not immediately apparent. A similar concept is a "buyer beware" claim, where the careful buyer should take the time to examine the item before accepting it, or obtain expert advice. On the other hand, the phrase "as is" does not disclaim "express" warranties: these may, for example, be created by the seller's description of an item. In other words, though the item may be sold "as is", nevertheless, if it for example does not conform to the seller's description of it, the buyer may void the sale. For example, a seller of a used automobile sells it to a buyer, and puts int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pigment
A pigment is a colored material that is completely or nearly insoluble in water. In contrast, dyes are typically soluble, at least at some stage in their use. Generally dyes are often organic compounds whereas pigments are often inorganic compounds. Pigments of prehistoric and historic value include ochre, charcoal, and lapis lazuli. Economic impact In 2006, around 7.4 million tons of inorganic, organic, and special pigments were marketed worldwide.

Ilmenite
Ilmenite is a titanium-iron oxide mineral with the idealized formula . It is a weakly magnetic black or steel-gray solid. Ilmenite is the most important ore of titanium and the main source of titanium dioxide, which is used in paints, printing inks, fabrics, plastics, paper, sunscreen, food and cosmetics. Structure and properties Ilmenite is a heavy (specific gravity 4.7), moderately hard (Mohs hardness 5.6 to 6), opaque black mineral with a submetallic luster. It is almost always massive, with thick tabular crystals being quite rare. It shows no discernible cleavage, breaking instead with a conchoidal to uneven fracture. Ilmenite crystallizes in the trigonal system with space group ''R''. The ilmenite crystal structure consists of an ordered derivative of the corundum structure; in corundum all cations are identical but in ilmenite Fe2+ and Ti4+ ions occupy alternating layers perpendicular to the trigonal c axis. Pure ilmenite is paramagnetic (showing only very weak attra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magnetic
Magnetism is the class of physical attributes that are mediated by a magnetic field, which refers to the capacity to induce attractive and repulsive phenomena in other entities. Electric currents and the magnetic moments of elementary particles give rise to a magnetic field, which acts on other currents and magnetic moments. Magnetism is one aspect of the combined phenomena of electromagnetism. The most familiar effects occur in ferromagnetic materials, which are strongly attracted by magnetic fields and can be magnetized to become permanent magnets, producing magnetic fields themselves. Demagnetizing a magnet is also possible. Only a few substances are ferromagnetic; the most common ones are iron, cobalt, and nickel and their alloys. The rare-earth metals neodymium and samarium are less common examples. The prefix ' refers to iron because permanent magnetism was first observed in lodestone, a form of natural iron ore called magnetite, Fe3O4. All substances exhibit som ...
