Lake Lefroy
Lake Lefroy is a large ephemeral salt lake in the Goldfields-Esperance region of Western Australia Western Australia (commonly abbreviated as WA) is a state of Australia occupying the western percent of the land area of Australia excluding external territories. It is bounded by the Indian Ocean to the north and west, the Southern Ocean to th .... It is north of Lake Cowan and approximately south of Boulder. The town of Kambalda is on the northern shore and the hamlet of Widgiemooltha near the southern edge. Description Lake Lefroy is a clay pan covered with a crust of salt that supports little vegetation. It fills episodically in response to heavy rainfall. Following inundation, a drying phase is relatively rapid due to high evaporation rates and surface water may only last for a few months. When the lake contains water there may be relatively large fluctuations in water level over very short periods. The shallow surface water in the lake is blown back and forth acro ...

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 ...

Surface Mines In Australia
A surface, as the term is most generally used, is the outermost or uppermost layer of a physical object or space. It is the portion or region of the object that can first be perceived by an observer using the senses of sight and touch, and is the portion with which other materials first interact. The surface of an object is more than "a mere geometric solid", but is "filled with, spread over by, or suffused with perceivable qualities such as color and warmth". The concept of surface has been abstracted and formalized in mathematics, specifically in geometry. Depending on the properties on which the emphasis is given, there are several non equivalent such formalizations, that are all called ''surface'', sometimes with some qualifier, such as algebraic surface, smooth surface or fractal surface. The concept of surface and its mathematical abstraction are both widely used in physics, engineering, computer graphics, and many other disciplines, primarily in representing the surfaces ...

Gold Mines In Western Australia
Gold is a chemical element with the Symbol (chemistry), 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 Brightness, 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 for temperature and pressure, standard conditions. Gold often occurs in Free element, free elemental (native state (metallurgy), native state), as Gold nugget, nuggets or grains, in Rock (geology), rocks, Vein (geology), 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Battle Of Trafalgar
The Battle of Trafalgar (21 October 1805) was a naval engagement between the British Royal Navy and the combined fleets of the French and Spanish Navies during the War of the Third Coalition (August–December 1805) of the Napoleonic Wars (1803–1815). As part of Napoleon's plans to invade England, the French and Spanish fleets combined to take control of the English Channel and provide the Grande Armée safe passage. The allied fleet, under the command of the French admiral, Pierre-Charles Villeneuve, sailed from the port of Cádiz in the south of Spain on 18 October 1805. They encountered the British fleet under Lord Nelson, recently assembled to meet this threat, in the Atlantic Ocean along the southwest coast of Spain, off Cape Trafalgar. Nelson was outnumbered, with 27 British ships of the line to 33 allied ships including the largest warship in either fleet, the Spanish ''Santísima Trinidad''. To address this imbalance, Nelson sailed his fleet directly at the allied ba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carbon In Pulp
Carbon in pulp (CIP) is an extraction technique for recovery of gold which has been liberated into a cyanide solution as part of the gold cyanidation process. Introduced in the early 1980s, Carbon in Pulp is regarded as a simple and cheap process. As such it is used in most industrial applications where the presence of competing silver or copper does not prohibit its use. In the case of high (i.e., 1%) copper content, froth flotation is more typical. Activated carbon acts like a sponge to dicyanoaurate, the main soluble gold species in gold extraction technologies. Hard carbon particles (much larger than the ore particle sizes) can be mixed with the solution. The gold cyanide complex adsorb onto the carbon and is proposed to be reduced back to the metal. Because the carbon particles are much larger than the ore particles, the coarse carbon can then be separated from the slurry by screening using a wire mesh. Loading gold into carbon 256px Leached pulp and carbon are tran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kambalda Nickel Operations
Kambalda Nickel Operations or Kambalda Nickel Mine is a surface and underground nickel mine as well as a nickel concentrator, near Kambalda East, Western Australia. The deposit was discovered in 1954 and the mine opened in 1967, operated by WMC Resources which was taken over by BHP in 2005. Prior to this, between 2001 and 2003, WMC ceased mining operations at Kambalda and divested itself of the mining assets. BHP, through its Nickel West operations, continues to operate the Kambalda Nickel Concentrator, with the facility having been shut down from 2018 to 2022. The mining leases are predominantly with Mincor Resources which has intermittently mined the former WMC workings. Kambalda was the first nickel mine in Western Australia. The mine also caused an international dispute between Singapore and Australia over nuclear waste disposal when a Caesium-137 density gauge lost at Kambalda contaminated a furnace in Singapore in 1978.

WMC Resources
WMC Resources Limited was an Australian diversified mining company. History Western Mining Corporation (WMC) was formed in 1933, when William Robinson, the Australian-born London-based managing director of Broken Hill Associated Smelters, was able to interest several large London-based mining companies into forming syndicates to develop gold mines in Australia. WMC's strategy was to use the newly emerging sciences of mining geology and related geochemistry and geophysics to find new gold deposits. It was a company based on the idea that if they applied good science to exploration, they would be successful. WMC began operations in Western Australia in December 1933 when it commenced an extensive aerial survey of the Eastern Goldfields. It acquired its first profitable mining operation in June 1935 when it took an option over a new gold discovery at Cox's Find, 43 miles northwest of Laverton. WMC pioneered district-scale aerial photography in the 1930s, flying many areas in W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
