Consolidated Zinc
Consolidated Zinc was an Australian mining company from 1905 to 1962. History The company's initial operations focused on extracting zinc from mine tailings of the Broken Hill Ore Deposit at Broken Hill, New South Wales, Australia. The company was founded in Melbourne on 9 September 1905 as the Zinc Corporation Limited, to exploit residual zinc concentrations with an estimated value of $12 million in the 6 million tons of mine tailings deposited from mining activities over the previous 20 years. Key figures involved in the effort included William Baillieu and William Sydney Robinson. Also involved was future U.S. president, but then a mining engineer working for Bewick, Moreing and Company, Herbert Hoover, who inspected the tailing dumps in the group's investigations prior to formation of the company. Other investors in the new company were Clark & Robinson (William Clark, Lionel Robinson and Company), and Arthur Terrell. They established concentrating mills at Broken Hill ...

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 desired materials, an ...

Metal Companies Of Australia
A metal (from Greek μέταλλον ''métallon'', "mine, quarry, metal") is a material that, when freshly prepared, polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well. Metals are typically ductile (can be drawn into wires) and malleable (they can be hammered into thin sheets). These properties are the result of the ''metallic bond'' between the atoms or molecules of the metal. A metal may be a chemical element such as iron; an alloy such as stainless steel; or a molecular compound such as polymeric sulfur nitride. In physics, a metal is generally regarded as any substance capable of conducting electricity at a temperature of absolute zero. Many elements and compounds that are not normally classified as metals become metallic under high pressures. For example, the nonmetal iodine gradually becomes a metal at a pressure of between 40 and 170 thousand times atmospheric pressure. Equally, some materials regarded as metals ...

Zinc Smelters
Zinc is a chemical element with the symbol Zn and atomic number 30. Zinc is a slightly brittle metal at room temperature and has a shiny-greyish appearance when oxidation is removed. It is the first element in group 12 (IIB) of the periodic table. In some respects, zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn2+ and Mg2+ ions are of similar size.The elements are from different metal groups. See periodic table. Zinc is the 24th most abundant element in Earth's crust and has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. The largest workable lodes are in Australia, Asia, and the United States. Zinc is refined by froth flotation of the ore, roasting, and final extraction using electricity (electrowinning). Zinc is an essential trace element for humans, animals, plants and for microorganisms and is necessary for prenatal and postnatal development. It is the second ...

Former Rio Tinto (corporation) Subsidiaries
A former is an object, such as a template, gauge or cutting die, which is used to form something such as a boat's hull. Typically, a former gives shape to a structure that may have complex curvature. A former may become an integral part of the finished structure, as in an aircraft fuselage, or it may be removable, being using in the construction process and then discarded or re-used. Aircraft formers Formers are used in the construction of aircraft fuselage, of which a typical fuselage has a series from the nose to the empennage, typically perpendicular to the longitudinal axis of the aircraft. The primary purpose of formers is to establish the shape of the fuselage and reduce the column length of stringers to prevent instability. Formers are typically attached to longerons, which support the skin of the aircraft. The "former-and-longeron" technique (also called stations and stringers) was adopted from boat construction, and was typical of light aircraft built until the ...

Merger
Mergers and acquisitions (M&A) are business transactions in which the ownership of companies, other business organizations, or their operating units are transferred to or consolidated with another company or business organization. As an aspect of strategic management, M&A can allow enterprises to grow or downsize, and change the nature of their business or competitive position. Technically, a is a legal consolidation of two business entities into one, whereas an occurs when one entity takes ownership of another entity's share capital, equity interests or assets. A deal may be euphemistically called a ''merger of equals'' if both CEOs agree that joining together is in the best interest of both of their companies. From a legal and financial point of view, both mergers and acquisitions generally result in the consolidation of assets and liabilities under one entity, and the distinction between the two is not always clear. In most countries, mergers and acquisitions must comp ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Haddon King
Haddon Rymer Forrester King (4 February 1905 – 1990), was an Australian geologist, winner of the Clarke Medal in 1972. King was born in Georgetown, British Guiana, son of George Forrester King and his wife Jessie Ann, née Kingsland. In 1926 he started as a surveyor’s assistant on the Geological Survey of British Guiana under the supervision of H. J. C. (Terence) Conolly. King obtained his surveyor’s licence in 1929 and then moved to Canada where he studied mining engineering at the University of Toronto (B.A.Sc., 1934). King gained experience in mineral exploration working with Conolly in the Timmins and Sudbury Basin regions. King was invited to join the newly formed Western Mining Corporation in Western Australia in 1934 `to apply the latest ideas in geology, geophysics, geochemistry and aerial photography to the scientific search for new mineral deposits’, collaborating with U.S. consultants. King became senior geologist in 1936. In 1953, King became chief geologist ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Gold
Gold is a chemical element with the symbol Au (from la, aurum) and atomic number 79. This makes it one of the higher atomic number elements that occur naturally. It is a bright, slightly orange-yellow, dense, soft, malleable, and ductile metal in a pure form. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions. Gold often occurs in free elemental ( native state), as nuggets or grains, in rocks, veins, and alluvial deposits. It occurs in a solid solution series with the native element silver (as electrum), naturally alloyed with other metals like copper and palladium, and mineral inclusions such as within pyrite. Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides). Gold is resistant to most acids, though it does dissolve in aqua regia (a mixture of nitric acid and hydrochloric acid), forming a soluble tetrachloroaurate anion. Gold is ...
