In mining, gangue is the commercially worthless material that surrounds, or is closely mixed with, a wanted mineral in an ore deposit. It is thus distinct from overburden, which is the waste rock or materials overlying an ore or mineral body that are displaced during mining without being processed. The separation of mineral from gangue is known as mineral processing, mineral dressing or ore dressing and it is a necessary and often significant aspect of mining. It can be a complicated process, depending on the nature of the minerals involved. For example, galena, an ore of lead, is usually found in large pieces within its gangue, so it does not normally need extensive processing to remove it; but cassiterite, the chief ore of tin, is usually disseminated as very small crystals throughout its gangue, so when it is mined from hard rock, the ore-bearing rock first needs to be crushed very finely, and then has to be subjected to sophisticated processes to separate the ore. For any particular ore deposit, and at any particular point in time, the concentration of the wanted mineral in the gangue material will determine whether it is commercially viable to mine that deposit. The ease with which the ore can be separated also plays an important part. Early mining ventures, with their relatively unsophisticated methods, often could not achieve a high degree of separation, so significant quantities of minerals found their way into the tailings dumps of mines. As the value of a mineral increases, or when new and cheaper means of processing the ore are introduced it has often become worthwhile to rework such old dumps to retrieve the minerals they still contain.

The Brady Bunch
The Brady Bunch is an American sitcom created by Sherwood Schwartz that aired from September 26, 1969, to March 8, 1974, on ABC. The series revolves around a large blended family with six children. Considered one of the last of the old-style family sitcoms, the series aired for five seasons and, after its cancellation in 1974, went into syndication in September 1975. While the series was never a critical success or hit series during its original run, it has since become a popular staple in syndication, especially among children and teenaged viewers. The Brady Bunch's success in syndication led to several television reunion films and spin-off series: The Brady Bunch Hour (1976–77), The Brady Girls Get Married (1981), The Brady Brides (1981), A Very Brady Christmas (1988), and The Bradys (1990). In 1995, the series was adapted into a satirical comedy theatrical film titled The Brady Bunch Movie, followed by A Very Brady Sequel in 1996. A second sequel, The Brady Bunch in the White House, aired on Fox in November 2002 as a made-for-television film. In 1997, "Getting Davy Jones" (season three, episode 12) was ranked number 37 on TV Guide's 100 Greatest Episodes of All-Time. The enduring popularity of the show has resulted in it becoming widely recognized as an American cultural icon.
Maureen Denise McCormick (born August 5, 1956) is an American actress, singer and author. She portrayed Marcia Brady on the ABC television sitcom The Brady Bunch, which ran from 1969 to 1974 and reprised the role in several of the numerous Brady Bunch spin-offs and films, including The Brady Kids, The Brady Bunch Hour, The Brady Brides and A Very Brady Christmas (1988). McCormick also appeared in The Idolmaker (1980) as well as a wide range of other supporting film roles. In the 1980s and 1990s, she ventured into stage acting, appearing in a variety of different roles and productions such as Wendy Darling in Peter Pan and Betty Rizzo in Grease. McCormick also had a brief career as a recording artist, releasing four studio albums with the Brady Bunch cast as well as touring with them. Her only release as a solo artist to date is a country music album, When You Get a Little Lonely (1995). Despite professional success on The Brady Bunch and its spin-offs, McCormick struggled largely in her personal life in the years following the original series' end. Addictions to cocaine and quaaludes, as well as bouts of depression and bulimia, all contributed to McCormick losing her reputation for reliability as an actress. Since the 2000s, she has appeared on several reality television series such as VH1's Celebrity Fit Club, CMT's Gone Country (which led to a short-lived spin-off series led by McCormick, Outsiders Inn) and the Australian version of I'm a Celebrity... Get Me Out of Here!, as well as guest spots on a wide range of television series. In 2008, McCormick published an autobiography, Here's the Story: Surviving Marcia Brady and Finding My True Voice, which debuted at number four on The New York Times bestseller list and garnered significant publicity and mild controversy.
An ore is a type of rock that contains minerals with important elements including metals. The ores are extracted through mining; these are then refined to extract the valuable element. The grade or concentration of an ore mineral, or metal, as well as its form of occurrence, will directly affect the costs associated with mining the ore. The cost of extraction must thus be weighed against the metal value contained in the rock to determine what ore can be processed and what ore is of too low a grade to be worth mining. Metal ores are generally oxides, sulfides, silicates, or "native" metals that are not commonly concentrated in the Earth's crust or "noble" metals such as gold. The ores must be processed to extract the metals of interest from the waste rock and from the ore minerals. Ore bodies are formed by a variety of geological processes. The process of ore formation is called ore genesis.
Malmberget ("The Ore Mountain", Finnish and Meänkieli: Malmivaara) is a locality and mining town situated in Gällivare Municipality, Norrbotten County, Sweden with 5,590 inhabitants in 2010. It is situated 5 kilometres from the municipal seat Gällivare. Malmberget is known as a major site for the extraction of iron ore from deep mines by the company LKAB. The iron ore mining started in 1741 at the Illuvaara mountain, later known as Gellivare malmberg and eventually just Malmberget. The first train which transported iron ore was loaded in 1888 - this was the beginning of the great iron ore rush which would change the entire area of Northern Lapland. In Malmberget there were lots of job opportunities but no dwellings - a striking resemblance to the conditions during some of the gold rushes in North America. During the first years, workers lived in shacks built from wasted dynamite crates. Right down the centre of Malmberget, the deep mine has reached daylight and thus created a huge hole called Kaptensgropen ("The Captain's Pit"). In March 2012, Kaptensgropen was joined with a new pit resulting from the 'Fabian'-deposit caving in as planned, and has grown southwards as the deep mining continues, and thus divided the town while making the old town centre uninhabitable and forcing many institutions (e.g. the two existing cinemas and the church) to move to the western part of Malmberget or, even more commonly, to the neighbouring town of Gällivare. Today Kaptensgropen is being filled up with stone which is dug up as a by-product from the underground mines. Kaptensgropen will eventually be filled in, but the uninhabitable area is continually growing as underground mining undermines the area and seismic events caused by the mining regularly shake the remaining parts of Malmberget. The future of Malmberget is currently uncertain, but prospecting by LKAB indicates that even more of Malmberget may have to move in the future. The moving of several large residential houses owned by the mining company, as well as private villas, has been a major issue locally for the past few years. The iron ore extracted from Malmberget is mainly transported by rail southeast to the port of Luleå. (See Swedish iron ore during World War II).
Character of Pig-iron.—Ores suitable for “gun-metal” should be reduced in the smelting-furnace, with charcoal and the warm blast, varying from 125° to 300° Fahr., depending upon the ore used. Iron thus made, or pig-iron, should be soft, yielding easily to the file and chisel; the appearance of the fracture should be uniform, with a brilliant aspect, dark gray color, and medium-sized crystals. Character of Gun-metal.—When remelted and cast into cannon, it should approach that degree of hardness which resists the file and chisel, but not so hard as to be bored and turned with much difficulty. Its color should be a bright, lively gray; crystals small, with acute angles, and sharp to the touch; structure uniform, close, and compact. Magnetite.—Octahedral Iron Ore.—Color iron-black. Streak black. Brittle. The black streak and magnetic properties distinguish this species from the following: Specular Iron Ore.—Hematite.—Often massive granular; sometimes lamellar or micaceous. Also pulverulent and earthy. Color, dark steel-gray or iron-black, and often when crystallized having a highly splendid lustre; streak-powder cherry-red or reddish-brown. The metallic varieties pass into an earthy ore of a red color, having none of the external characters of the crystals, but perfectly corresponding to them when they are pulverized, the powder they yield being of a deep red color, and earthy or without lustre. Sometimes slightly attracted by the magnet. Limonite.—Brown Iron Ore.—Usually massive, and often with a smooth botryoidal or stalactitic surface, having a compact fibrous structure within. Also earthy. Color, dark brown to ochre-yellow; streak, yellowish-brown to dull yellow. Lustre, sometimes sub-metallic; often dull and earthy; on a surface of fracture frequently silky. Spathic Iron.—Carbonate of Iron.—Chalybite.—Usually massive, with a foliated structure, somewhat curving. Sometimes in globular concretions or implanted globules. Color, light grayish to brown; often dark brownish-red, or nearly black on exposure. Streak, uncolored. Lustre, pearly to vitreous; translucent to nearly opaque.

An ore shoot is a mass of ore deposited in a vein.The ore shoot consists of the most valuable part of the ore deposit. An ore shoot is the area of concentration containing primary ore along the veins present in the rocks.
Escondida is a copper mine in the Atacama Desert in Antofagasta Region, Chile. The Escondida deposit is one of a cluster of porphyry coppers in an elongated area about 18 km north-south and 3 km east-west and is associated with the 600 km long West Fissure (Falla Oeste) system, which is in turn associated with most of the major Chilean porphyry deposits. A barren, leached cap, in places up to 300 metres thick, overlies a thick zone of high grade secondary supergene mineralisation of the main orebody, largely chalcocite and covellite, which in turn overlies the unaltered primary mineralisation of chalcopyrite, bornite and pyrite.At mid 2007, Escondida had total proven and probable reserves of 34.7 million tonnes of copper, of which 22.5 million tonnes is estimated to be recoverable. Total resources (including reserves) were 57.6 million tonnes of copper, of which 33.0 million tonnes should be recovered. Exploration continues.Sulfide ore, which contributes 77% of the recoverable copper reserve, is crushed and milled in one of the two concentrators and the copper concentrate is separated out using froth flotation. Approximately 86% of the copper is recovered. It is piped down to the port of Coloso, where it is dewatered before shipping. Oxide ore, 4% of recoverable copper, is crushed, agglomerated and then acid leached in large heaps, and the copper is recovered from the leach solutions as copper cathode in a solvent extraction/electrowinning (SX/EW) plant. Recovery is 68%. The low grade sulfide ore contributes 19% of recoverable copper. It is also crushed and dumped on large heaps, but here the leaching occurs through oxidation induced by microorganisms. The copper is also recovered by SX/EW.In 2006, 338.6 million tonnes were mined (928,000 tonnes per day), of which 251.5 million tonnes were waste and oxide ore. Sulphide ore totalled 87.1 million tonnes or 239,000 tonnes per day. The two camps, San Lorenzo and 2000, cater to 7,000 people daily.In 2005, Degremont Industry was asked to install a new Sea Water Reverse Osmosis plant with capacity to produce 12 Million gallons of clean water per day.Construction of work force accommodation camps and field offices are needed services in order to have the mine operating, on this note Tecno Fast in 2012 was hired to build the second phase of the respective workforce accommodation camp for Escondida Mine.
Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour from dark grey, bright yellow, or deep purple to rusty red. The iron itself is usually found in the form of magnetite (Fe3O4, 72.4% Fe), hematite (Fe2O3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)·n(H2O), 55% Fe) or siderite (FeCO3, 48.2% Fe). Ores containing very high quantities of hematite or magnetite (greater than about 60% iron) are known as "natural ore" or "direct shipping ore", meaning they can be fed directly into iron-making blast furnaces. Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel. Indeed, it has been argued that iron ore is "more integral to the global economy than any other commodity, except perhaps oil".

In geology, a lode is a deposit of metalliferous ore that fills or is embedded in a fissure in a rock formation or a vein of ore that is deposited or embedded between layers of rock. The generally accepted hydrothermal model of lode deposition posits that metals dissolved in hydrothermal solutions deposit the gold or other metallic minerals inside the fissures in the pre-existing rocks. Lode deposits are distinguished primarily from placer deposits, where the ore has been eroded out from its original depositional environment and redeposited by sedimentary forces. A third process for ore deposition is as an evaporite. A stringer lode is one in which the rock is so permeated by small veinlets that rather than mining the veins, the entire mass of ore and the enveined county rock is mined. It is so named because of the irregular branching of the veins into many anastomosing stringers, so that the ore is not separable from the country rock. One of largest silver lodes was the Comstock Lode in Nevada, although it is overshadowed by the more recently discovered Cannington Lode in Queensland, Australia. The largest gold lode in the United States was the Homestake Lode. The Broken Hill Lode in South Australia, is the largest lead-zinc lode ever discovered.
Tailings, also called mine dumps, culm dumps, slimes, tails, refuse, leach residue or slickens, are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore. Tailings are distinct from overburden, which is the waste rock or materials overlying an ore or mineral body that are displaced during mining without being processed. The extraction of minerals from ore can be done two ways: placer mining, which uses water and gravity to extract the valuable minerals, or hard rock mining, which uses pulverization of rock, then chemicals. In the latter, the extraction of minerals from ore requires that the ore be ground into fine particles, so tailings are typically small and range from the size of a grain of sand to a few micrometres. Mine tailings are usually produced from the mill in slurry form. In some situations, tailings represent an external cost of mining This is particularly true of early mining operations which did not take adequate steps to make tailings areas environmentally safe after closure. Modern day mines, particularly in jurisdictions with well-developed mining regulations or operated by responsible mining companies, often incorporate the rehabilitation and proper closure of tailings areas in the mining costs and activities. For example, the province of Quebec, Canada, requires not only submission of closure plan before the start of mining activity, but also the deposit of a financial guarantee equal to 100% of the estimated rehabilitation costs. Tailings dams are often the most significant environmental liability for a mining project.
Malmborg is a Swedish surname. Malmborg means "Ore Castle" in Swedish, with malm meaning ore and borg meaning castle. The look of a borg however, is closer to a fortress or a stronghold than a castle. Borg could also reference a mountain, so the name would then be "the village in which ore is mined", or "the mountain where we mine ore".
Gossan is intensely oxidized, weathered or decomposed rock, usually the upper and exposed part of an ore deposit or mineral vein. In the classic gossan or iron cap all that remains is iron oxides and quartz often in the form of boxworks, quartz lined cavities retaining the shape of the dissolved ore minerals. In other cases quartz and iron oxides, limonite, goethite, and jarosite, exist as pseudomorphs replacing the pyrite and primary ore minerals. Frequently gossan appears as a red stain against the background rock and soil due to the abundance of oxidized iron and the gossan may be a topographic positive area due to the abundance of erosion resistant quartz and iron oxides. Although most gossans are red, orange, or yellow, black gossans from manganese oxides such as pyrolusite, manganite, and especially psilomelane form at the oxidized portion of Mn-rich mineral deposits. In the 19th and 20th centuries gossans were important guides to buried ore deposits used by prospectors in their quest for metal ores. An experienced prospector could read the clues in the structure of the gossans to determine the type of mineralization likely to be found below the iron cap.
