Gemco
The Groote Eylandt Mining Company, known by its acronym GEMCO, is an Australian company that was commissioned to mine high grade manganese ore. GEMCO is majority owned by South32. It runs its operation on 84 square kilometres (32 sq. mi.) of the Arnhem Land Aboriginal Reserve, which is part of Groote Eylandt, a 2,326 square kilometre (898 sq. mi.) island in the Gulf of Carpentaria that has a population of 1539. The company is one of three manganese ore mining companies in Australia. GEMCO uses a mining extraction method called open cut strip mining. It sends its ore to be smelted at the Tasmanian Electro Metallurgical Company (TEMCO). TEMCO, established in 1965, is Australia's only ferroalloy smelter site, situated at Bell Bay, Tasmania, north of Launceston at the other end of the continent. The company extracts roughly 5 million tonnes of manganese ore every year. In 1964, GEMCO leased land for mine from Church Missionary Society at Angurugu, Northern Territory on Groote Eylandt wi ...

Manganese Refinery At Groote Eylandt
Manganese is a chemical element; it has symbol Mn and atomic number 25. It is a hard, brittle, silvery metal, often found in minerals in combination with iron. Manganese was first isolated in the 1770s. It is a transition metal with a multifaceted array of industrial alloy uses, particularly in stainless steels. It improves strength, workability, and resistance to wear. Manganese oxide is used as an oxidising agent, as a rubber additive, and in glass making, fertilisers, and ceramics. Manganese sulfate can be used as a fungicide. Manganese is also an essential human dietary element, important in macronutrient metabolism, bone formation, and free radical defense systems. It is a critical component in dozens of proteins and enzymes. It is found mostly in the bones, but also the liver, kidneys, and brain. In the human brain, the manganese is bound to manganese metalloproteins, most notably glutamine synthetase in astrocytes. Manganese is commonly found in laboratories in the form ...

Gulf Of Carpentaria
The Gulf of Carpentaria is a sea off the northern coast of Australia. It is enclosed on three sides by northern Australia and bounded on the north by the eastern Arafura Sea, which separates Australia and New Guinea. The northern boundary is generally defined as a line from Slade Point, Queensland (the northwestern corner of Cape York Peninsula) in the northeast, to Cape Arnhem on the Gove Peninsula, Northern Territory (the easternmost point of Arnhem Land), in the west. At its mouth, the Gulf is wide, and further south, . The north-south length exceeds . It covers a water area of about . The general depth is between with a maximum depth of . The tidal range in the Gulf of Carpentaria is between . The Gulf and adjacent Sahul Shelf were dry land at the peak of the last ice age 18,000 years ago when global sea level was around below its present position. At that time a large, shallow lake occupied the centre of what is now the Gulf. The Gulf hosts a submerged coral reef p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mining Companies Of Australia
Mining is the extraction of valuable geological materials and minerals from the surface of the Earth. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. The ore must be a rock or mineral that contains valuable constituent, can be extracted or mined and sold for profit. 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, and final reclamation or restoration of the land after the mine is closed. Mining materials are often obtained from ore bodies, lodes, veins, seams, reefs, or placer deposits. The exploitation of th ...
