Mount Lyell Remediation And Research And Demonstration Program
The Mount Lyell Remediation and Research and Demonstration Program was a joint rehabilitation programme between the Supervising Scientist Australia and the Department of Environment and Land Management, Tasmania to clean up the King River, Queen River and Macquarie Harbour. This was following over 100 years of mine waste and town waste from Queenstown being emptied into the rivers. It was conducted after the closing of the Mount Lyell Mining and Railway Company in 1994, and most reports were produced by 1996. At the time of the final report it was claimed that the program was one of Australia's most comprehensive response to large scale environmental damage. The review of the effluent and environment of the Mount Lyell mining lease resulted in reports that were published, and the new owner of the Mount Lyell lease - Copper Mines of Tasmania Copper Mines of Tasmania is the successor company to the Mount Lyell Mining and Railway Company that operated in Queenstown, Tasmania f ...

Land Rehabilitation
Land rehabilitation as a part of environmental remediation is the process of returning the land in a given area to some degree of its former state, after some process (industry, natural disasters, etc.) has resulted in its damage. Many projects and developments will result in the land becoming degraded, for example mining, farming and forestry. Mine rehabilitation Modern mine rehabilitation aims to minimize and mitigate the environmental effects of modern mining, which may in the case of open pit mining involve movement of significant volumes of rock. Rehabilitation management is an ongoing process, often resulting in open pit mines being backfilled. After mining finishes, the mine area must undergo rehabilitation. * Waste dumps are contoured to flatten them out, to further stabilize them against erosion. * If the ore contains sulfides it is usually covered with a layer of clay to prevent access of rain and oxygen from the air, which can oxidize the sulfides to produce sulfur ...

Queen River, Tasmania
The Queen River, part of the King River catchment, is a minor perennial river located in the West Coast region of Tasmania, Australia. Course and features The Queen River rises below , sourced by runoff from the West Coast Range and in particular the peaks of Mount Lyell and Mount Owen. The two branches of the river, West Queen River and East Queen River, merge north of and flow through the city and continue south, joined by one minor tributary before reaching its confluence with the King River. The river valley is low-lying and narrow, and the subsequent fogs are notable in their effect, some created by smelter fumes in earlier years. In April 1906, a significant flooding occurred in Queenstown and the southern part of the town due to the river overflowing. Subsequent recorded floods include in 1922, 1937 and 1954.

Macquarie Harbour
Macquarie Harbour is a shallow fjord in the West Coast region of Tasmania, Australia. It is approximately , and has an average depth of , with deeper places up to . It is navigable by shallow-draft vessels. The main channel is kept clear by the presence of a rock wall on the outside of the channel's curve. This man-made wall prevents erosion and keeps the channel deep and narrow, rather than allowing the channel to become wide and shallow. A reported Aboriginal name for the harbour is ''Parralaongatek''. The harbour was named in honour of Scottish Major General Lachlan Macquarie, the fifth Colonial Governor of New South Wales. History James Kelly wrote in his narrative ''First Discovery of Port Davey and Macquarie Harbour'' how he sailed from Hobart in a small open five-oared whaleboat to discover Macquarie Harbour on 28 December 1815. However, different accounts of the journey have indicated different methods and dates of the discovery. In the commentary to the ''Historical ...

Queenstown, Tasmania
Queenstown is a town in the West Coast region of the island of Tasmania, Australia. It is in a valley on the western slopes of Mount Owen on the West Coast Range. At the , Queenstown had a population of 1,808 people. History Queenstown's history has long been tied to the mining industry. This mountainous area was first explored in 1862. It was long after that when alluvial gold was discovered at Mount Lyell, prompting the formation of the Mount Lyell Gold Mining Company in 1881. In 1892, the mine began searching for copper. The final name of the Mount Lyell company was the Mount Lyell Mining and Railway Company. Early in 1895 a Post Office was opened at Penghana, at the Queen River fork and crossing, about a kilometre north of present-day Queenstown on the road to Strahan; James Robertson was appointed the first postmaster. The only other substantial building nearby was Robertson & Hunter's store. Queenstown Post Office opened on 21 November 1896 and the Penghana office c ...

Mount Lyell Mining And Railway Company
Mount Lyell Mining and Railway Company was a Tasmanian mining company formed on 29 March 1893, most commonly referred to as ''Mount Lyell''. Mount Lyell was the dominant copper mining company of the West Coast from 1893 to 1994, and was based in Queenstown, Tasmania. Following consolidation of leases and company assets at the beginning of the twentieth century, Mount Lyell was the major company for the communities of Queenstown, Strahan and Gormanston. It remained dominant until its closure in 1994. The Mount Lyell mining operations produced more than a million tonnes of copper, 750 tonnes of silver and 45 tonnes of gold since mining commenced in the early 1890s – which is equivalent to over 4 billion dollars worth of metal in 1995 terms. History In the early stage of operations, Mount Lyell was surrounded by smaller competing leases and companies. Eventually they were all absorbed into Mount Lyell operations, or were closed down. In 1903 the North Mount Lyell Copper Co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copper Mines Of Tasmania
Copper Mines of Tasmania is the successor company to the Mount Lyell Mining and Railway Company that operated in Queenstown, Tasmania for just short of one hundred years. History The first form of the company existed during the time of the Mount Lyell Remediation and Research and Demonstration Program. Following the first form going into administration in 1998 the mine was then acquired in 1999 by Monte Cello BV. First it operated as a subsidiary and then acquired by Sterlite Industries (India) Limited. It is now owned by Vedanta Resources. Its mine output goes to supply the companies copper smelter in Tuticorin, India. Production stopped at the mine in January 2014 following three deaths. Its reopening was subsequently prevented by a rockfall. As of July 2014, it was not expected to reopen for up to three years.
