1. Muruntau. This mining complex, located in Uzbekistan and consisting of open-pit mine and heap leach operations, is believed to produce about 2.6 million ounces of gold in 2014. Huge open-pit mine has following dimensions: 3.35 km – length, 2.5 km – width and 560 m – depth. Due to depletion of oxide reserves, Navoi Mining and Metallurgical Combinat, state-owned operator of this mine, has recently commissioned world’s biggest BIOX® plant. Keeping in mind stunning remaining resource base, which estimated at about 170 million ounces of gold, this operation has all chances to keep world’s leadership position in a longer term period.

After mining finishes, the mine area may undergo land rehabilitation. Waste dumps are contoured to flatten them out, to further stabilize them. 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 sulfuric acid, a phenomenon known as acid mine drainage.[18] This is then generally covered with soil, and vegetation is planted to help consolidate the material. Eventually this layer will erode, but it is generally hoped that the rate of leaching or acid will be slowed by the cover such that the environment can handle the load of acid and associated heavy metals.[19] There are no long term studies on the success of these covers due to the relatively short time in which large scale open pit mining has existed. It may take hundreds to thousands of years for some waste dumps to become "acid neutral" and stop leaching to the environment. The dumps are usually fenced off to prevent livestock denuding them of vegetation. The open pit is then surrounded with a fence, to prevent access, and it generally eventually fills up with ground water. In arid areas it may not fill due to deep groundwater levels.[20] Instead of returning the land to its former natural state, it may also be reused, converting it into recreational parks or even residential/mixed communities.[21]Copyright 2014 American Diatomite, Inc.
Open-cast mines are dug on benches, which describe vertical levels of the hole. The interval of the benches depends on the deposit being mined, the mineral being mined, and the size of the machinery that is being used. Generally, large mine benches are 12 to 15 metres thick.[5][6] In contrast, many quarries do not use benches, as they are usually shallow.[7] Mining can be conducted on more than one bench at a time, and access to different benches is done with a system of ramps. The width of each bench is determined by the size of the equipment being used, generally 20-40 metres wide.[8] Downward ramps are created to allow mining on a new level to begin. This new level will become progressively wider to form the new pit bottom.[9]
Most walls of the pit are generally mined on an angle less than vertical. Waste rock is stripped when the pit becomes deeper, therefore this angle is a safety precaution to prevent and minimize damage and danger from rock falls. However, this depends on how weathered and eroded the rocks are, and the type of rocks involved. It also depends on the amount of structural weaknesses occur within the rocks, such as a faults, shears, joints or foliations.
The walls are stepped. The inclined section of the wall is known as the batter, and the flat part of the step is known as the bench or berm. The steps in the walls help prevent rock falls continuing down the entire face of the wall. In some instances additional ground support is required and rock bolts, cable bolts and shotcrete are used. De-watering bores may be used to relieve water pressure by drilling horizontally into the wall, which is often enough to cause failures in the wall by itself.[10]
A haul road is usually situated at the side of the pit, forming a ramp up which trucks can drive, carrying ore and waste rock.[11]
Open-pit mines create a significant amount of waste. Almost one million tons of ore and waste rock can move from the largest mines per day, and a couple thousand tons moved from small mines per day.[12] There is generally four main operations in a mine that contribute to this load: drilling, blasting, loading and hauling.
Waste rock is hauled to a waste dump. Waste dumps can be piled at the surface of the active pit, or in previously mined pits.
Leftover waste from processing the ore is called tailings, and is generally in the form of a slurry. This is pumped to a tailings dam or settling pond, where the water is reused or evaporated. Tailings dams can be toxic due to the presence of unextracted sulfide minerals, some forms of toxic minerals in the gangue, and often cyanide which is used to treat gold ore via the cyanide leach process. If proper environmental protections are not in place, this toxicity can harm the surrounding environment.[13]
Open-pit mining involves the process of disrupting the ground, which leads to the creation of air pollutants. The main source of air pollutants comes from the transportation of minerals, but their are various other factors including drilling, blasting and the loading and unloading of overburden.[14] These type of pollutants cause significant damage to public health and safety in addition to damaging the air quality. The inhalation of these pollutants can cause issues to the lungs and ultimately increase mortality.[15] Furthermore, the pollutants affect flora and fauna in the areas surrounding open-pit mines.
Open-pit gold mining is one of the highest potential mining threats on the environment as it affects the air and water chemistry. The exposed dust may be toxic or radioactive, making it a health concern for the workers and the surrounding communities.[16]
A form of open-cast quarrying may be carried out as 'untopping'. This is done where a previous underground mine is becoming uneconomic or worked-out, but still leaves valuable rock in place, often as a result of pillar and stall working. Untopping removes the overburden from above this, opens up the mine from above, and then allows the previously 'trapped' minerals to be won.
Untopping was a feature of Welsh slate workings in the 1930s and 2000s, where Martyn Williams-Ellis, manager at Llechwedd found that earlier Victorian workings could be kept profitable with the newly mechanised techniques for bulk excavation to extract their pillars, and more recently across a number of worked-out mines.

Klondex Mines
From Wikipedia, the free encyclopedia
Klondex Mines was a North American gold-mining company, based in Reno, Nevada and Vancouver, British Columbia. It had three operating mines in Nevada and one in Manitoba.[1] and was listed on the Toronto Stock Exchange[2] and the NYSE American.[3] In March 2018, it was acquired by Hecla Mining.[4]
History[edit]
Klondex Mines was founded in 1975, through the spinoff of the Fire Creek Project in Nevada from Placer Development.[5] Until 2012, Klondex was principally engaged in exploration of its Fire Creek Project.[5] It attempted to sell this project to several suitors in the 2000s, but was not successful in doing so.[5]
In 2011, a dissident shareholder group successfully proposed a new board of directors.[6] In September 2012, the current CEO, Paul Huet, took control, as the result of another proxy battle.[7] Huet had experience with the company, as part of previous teams examining the possibility of buying its Fire Creek project. At that time, the company was in dire financial straits.[7]
In February 2014, the company bought the Midas mine and mill in Nevada from Newmont Mining for US$83 million.[8] Huet had experience with the mine, having previously been the mine manager for seven years. In January 2016, the company purchased the Rice Lake gold mine (also called the True North mine) in Manitoba for US$32 million, from creditors.[9] Also in 2016, it purchased the Hollister mine in Nevada for US$80 million.[10]
In 2018, the company laid off 90 employees at its True North mine, as the result of disappointing production in 2017.[11] Production was only about 25,000 ounces, as opposed to the expected 50,000 ounces.[11]
In March 2018, the company was acquired for US$462 million by Hecla Mining. At the same time, Klondex's Canadian assets (principally the True North mine) were spun out into a new entity, Klondex Canada, listed on the TSX Venture Exchange.
