States And Territories Of Australia
The states and territories are federated administrative divisions in Australia, ruled by regional governments that constitute the second level of governance between the federal government and local governments. States are self-governing polities with incomplete sovereignty (having ceded some sovereign rights to federation) and have their own constitutions, legislatures, departments, and certain civil authorities (e.g. judiciary and law enforcement) that administer and deliver most public policies and programs. Territories can be autonomous and administer local policies and programs much like the states in practice, but are still constitutionally and financially subordinate to the federal government and thus have no true sovereignty. The Federation of Australia constitutionally consists of six federated states (New South Wales, Queensland, South Australia, Tasmania, Victoria, and Western Australia) and ten federal territories,Section 2B, Acts Interpretation Act 1901 out of ...

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 ...

Gold Mining
Gold mining is the extraction of gold resources by mining. Historically, mining gold from alluvial deposits used manual separation processes, such as gold panning. However, with the expansion of gold mining to ores that are not on the surface, has led to more complex extraction processes such as pit mining and gold cyanidation. In the 20th and 21st centuries, most volume of mining was done by large corporations, however the value of gold has led to millions of small, artisanal miners in many parts of the Global South. Like all mining, human rights and environmental issues are common issues in the gold mining industry. In smaller mines with less regulation, health and safety risks are much higher. History The exact date that humans first began to mine gold is unknown, but some of the oldest known gold artifacts were found in the Varna Necropolis in Bulgaria. The graves of the necropolis were built between 4700 and 4200 BC, indicating that gold mining could be at least 700 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Care And Maintenance
Care and maintenance is a term used in the mining industry to describe processes and conditions on a closed minesite where there is potential to recommence operations at a later date. During a care and maintenance phase, production is stopped but the site is managed to ensure it remains in a safe and stable condition. Causes The mine might be considered to be temporarily unviable, due to current economic conditions or unfavourable resource prices, which are expected to improve at a later date. Declining ore grades at some mines can also be a reason for care and maintenance announcements. In some cases controlling interest companies decide not to further funding for subsidiary operations. During closure While the mine is closed, a care and maintenance program will manage environmental risks associated with tailings dumps, hazardous materials and open and underground pits. Care of idle plant and machinery will also be included in the program. Public health and safety consideratio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Native Title
Aboriginal title is a common law doctrine that the land rights of indigenous peoples to customary tenure persist after the assumption of sovereignty under settler colonialism. The requirements of proof for the recognition of aboriginal title, the content of aboriginal title, the methods of extinguishing aboriginal title, and the availability of compensation in the case of extinguishment vary significantly by jurisdiction. Nearly all jurisdictions are in agreement that aboriginal title is inalienable, and that it may be held either individually or collectively. Aboriginal title is also referred to as indigenous title, native title ( in Australia), original Indian title ( in the United States), and customary title (in New Zealand). Aboriginal title jurisprudence is related to indigenous rights, influencing and influenced by non-land issues, such as whether the government owes a fiduciary duty to indigenous peoples.

Kalgoorlie, Western Australia
Kalgoorlie is a city in the Goldfields–Esperance region of Western Australia, located east-northeast of Perth at the end of the Great Eastern Highway. It is sometimes referred to as Kalgoorlie–Boulder, as the surrounding urban area includes the historic townsite of Boulder and the local government area is the City of Kalgoorlie–Boulder. Kalgoorlie-Boulder lies on the traditional lands of the Wangkatja group of peoples.The name "Kalgoorlie" is derived from the Wangai word ''Karlkurla'' or ''Kulgooluh'', meaning "place of the silky pears". The city was established in 1893 during the Western Australian gold rushes. It soon replaced Coolgardie as the largest settlement on the Eastern Goldfields.

Open-pit Mining
Open-pit mining, also known as open-cast or open-cut mining and in larger contexts mega-mining, is a surface mining technique of extracting rock or minerals from the earth from an open-air pit, sometimes known as a borrow. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mining. Open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface. It is applied to ore or rocks found at the surface because the overburden is relatively thin or the material of interest is structurally unsuitable for tunnelling (as would be the case for cinder, sand, and gravel). In contrast, minerals that have been found underground but are difficult to retrieve due to hard rock, can be reached using a form of underground mining. To create an open-pit mine, the miners must determine the information of the ore that is underground. This is done through drilling of probe holes in the ground, then plotting ea ...
