Effects of cyanide to the environment
 
01:40
Cyanide, in the form of a very dilute sodium cyanide solution, is used to dissolve and separate gold from ore.The process used to extract gold using cyanide was developed in Scotland in 1887, and was first used in large scale commercial mining by the New Zealand Crown Mines Company at Karangahake in 1889. Cyanide leaching is considered to be a much safer alternative to extraction with liquid mercury, which was previously the main method of removing gold from ore. [5] Cyanide leaching has been the dominant gold extraction technology since the 1970s, although small-scale and artisanal miners continue to use mercury in some areas of the world.In Canada, more than 90% of mined gold is extracted from ore using cyanide. - See more at: http://www.miningfacts.org/environment/what-is-the-role-of-cyanide-in-mining/#sthash.d61bXQbG.dpuf

Heap Leaching of Gold and Silver Ores
 
10:03
HEAP LEACHING OF GOLD & SILVER ORES Heap leaching is the process to extract precious metals like gold, silver, copper etc, from their ore by placing them on a pad (a base) in a heap and sprinkling a leaching solvent, such as cyanide or acids, over the heap.. This process dissolves the metals and they collect at the bottom of the pad. The metal is then further processed. This methodology is mostly used for low-grade ores, and the basic processing steps involve crushing and sometime grinding.. The stages for heap leaching can be described as: 1. Ground Preparation and pad construction: Here the soil on a slightly sloping ground is compacted and covered by an impermeable pad (can be made of plastic). 2. Ore stacking: Then the crushed ore is stacked in the form of big heaps. Amount of fines is decreases as low as possible to improve permeability. 3. Then the leaching agent such as cyanide or acid is sprayed over the heap. 4. As, the reagent passes through the heap; the valuable metals get dissolved in it. 5. The solution containing metal is drained from the heap and collected in a pond and the solution is sent for subsequent process for metal recovery.. Is there any investors who are interested to cooperate for gold mining area in my village, actually typical of the material in my village is good proses by Heap Leaching Method process..

Europe's Worst Ecological Disaster Since Chernobyl (2000)

Cyanide River (2000): A leak of cyanide near Baia Mare, Romania, into the Someș River by the gold mining company Aurul spelled disaster for the Hungarian fishing and culinary industries. Subscribe to Journeyman here: http://www.youtube.com/subscription_center?add_user=journeymanpictures# When the tailings dam of the Esmeralda Explorations Gold Mine in Romania broke, it sent a torrent of cyanide and heavy metals into the Szamos and Tisza Rivers downstream in Hungary. Today both rivers are dead. The fishermen who harvested their riches must now shovel the carcasses of prime fish into skips. Fishing communities are desperate for compensation. Yet despite the evidence of disastrous pollution, officials from Esmeralda are in deep denial. It "could be increased salinity," according to the spokesperson from the mine's Australian co-owners. Yet with their stinging eyes and itchy throats the fishermen are angered by the mine rep's response. "I would start by making him a good soup of fish poisoned by cyanide and making him eat it." Up river in Romania the company are heightening the earthen banks of the mine's wastewater pools. They blame unusually heavy snow for causing the January 30th spill. To Hungary's Foreign Affairs spokesperson it's a reason but not an excuse - the banks simply should have been designed to cope. As this more recent spill demonstrates, the mining operations are unsafe. ABC Australia speaks to those involved and affected by the disaster.

The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original). https://en.wikipedia.org/wiki/Gold_mining Wikipedia license: http://creativecommons.org/licenses/by-sa/3.0/ Gold mining is the removal of gold from the ground. There are several techniques and processes by which gold may be extracted from the earth. Placer mining Panning Gold panning is mostly a manual technique of separating gold from other materials. Wide, shallow pans are filled with sand and gravel that may contain gold. The pan is submerged in water and shaken, sorting the gold from the gravel and other material. As gold is much denser than rock, it quickly settles to the bottom of the pan. The panning material is usually removed from stream beds, often at the inside turn in the stream, or from the bedrock shelf of the stream, where the density of gold allows it to concentrate, a type called placer deposits. Gold panning is the easiest technique for searching for gold, but is not commercially viable for extracting gold from large deposits, except where labor costs are very low or gold traces are substantial. Panning is often marketed as a tourist attraction on former gold fields. Before large production methods are used, a new source must be identified and panning is useful to identify placer gold deposits to be evaluated for commercial viability. Sluicing Using a sluice box to extract gold from placer deposits has long been a common practice in prospecting and small scale mining. A sluice box is essentially a man made channel with riffles set in the bottom. The riffles are designed to create dead zones in the current to allow gold to drop out of suspension. The box is placed in the stream to channel water flow. Gold bearing material is placed at the top of the box. The material is carried by the current through the box where gold and other dense material settles out behind the riffles. Less dense material flows out of the box as tailings. Larger commercial placer mining operations employ screening plants, or trommels, to remove the larger alluvial materials such as boulders and gravel, before concentrating the remainder in a sluice box or jig plant. These operations typically include diesel powered, earth moving equipment, including excavators, bulldozers, wheel loaders, and rock trucks. Dredging Although this method has largely been replaced by modern methods, some dredging is done by small scale miners using suction dredges... Gold ore processing In placer mines, the gold is recovered by gravity separation. For hard rock mining, other methods are usually used. Cyanide process Cyanide extraction of gold may be used in areas where fine gold bearing rocks are found. Sodium cyanide solution is mixed with finely ground rock that is proven to contain gold or silver, and is then separated from the ground rock as gold cyanide or silver cyanide solution. Zinc is to precipitate out residual zinc as well as the silver and gold metals. The zinc is removed with sulfuric acid, leaving a silver or gold sludge that is generally smelted into an ingot then shipped to a metals refinery for final processing into 99.9999% pure metals. Advancements in the 1970s have seen activated carbon used in extracting gold from the leach solution. The gold is absorbed into the porous matrix of the carbon. Activated carbon has so much internal surface area,[5] that fifteen grams (half an ounce) has the equivalent surface area of the Melbourne Cricket Ground (18,100 square metres (195,000 sq ft)). The gold can be removed from the carbon by using a strong solution of caustic soda and cyanide, a process known as elution. Gold is then plated out onto steel wool through electrowinning... The cyanide technique is crude and is commonly used in low grade gold and silver ore processing. There are many environmental hazards associated with this extraction method in addition to the high toxicity of the cyanide itself. An acute example was demonstrated in the 2000 Baia Mare cyanide spill environmental disaster when a break in a waste pond dam gold mine reprocessing facility near Baia Mare in northern Romania released approximately 100,000 cubic metres (3,500,000 cu ft) of waste water contaminated with heavy metal sludge and up to 120 long tons (122 t) of cyanide into the Tisza River...

Six of Augusta's current and former directors also served on the board of Sargold Resource Corporation. Sargold owned a gold mine near the small farming village of Furtei in southern Sardinia. The common Sargold and Augusta directors include: Augusta Chairman Richard Warke, Augusta President and CEO Gil Clausen, and directors Donald B. Clark, Robert P. Wares and Christopher M. H. Jennings. Former Augusta director Michael A. Steeves also served on the Sargold board. (Clark resigned from the Augusta board on Nov. 12, 2012.) "Cyanide Beach" documents Sargold's business history in Sardinia including: • Failing to pay local contractors, forcing vendors to obtain court judgments; • Misspending a $787,000 Sardinian government loan that was supposed to be used to develop an underground mine; • Issuing misleading press releases to investors, including a release that overstated gold reserves in Furtie forcing the Toronto Venture Stock Exchange to require the company to retract the projection. • Using its obligation to implement environmental restoration of the Furtei gold mine as leverage with Sardinian government officials in a failed attempt to gain gold mining rights elsewhere in Sardinia; • Failing to disclose Mr. Warke's personal bankruptcy in regulatory filings between 2003 and 2005; • Failing to disclose to investors in annual proxy reports that a Cayman Islands hedge fund controlled more than 10 percent of Sargold's stock between 2005 and 2007. Sargold's conduct in Sardinia left a lasting impression on its former business partners. Franco Cherchi, a former president of Sargold's Gold Mines of Sardinia subsidiary, reported directly to Mr. Warke is interviewed in his office in Iglesias, Sardinia. When asked if Mr. Warke was a man of his word, Cherchi replied with smile: "When it's no longer convenient for him, he withdraws the promise." Additional information on Sargold and a detailed business history of Mr. Warke, and his long time associate, Mr. Clark, is available at http://www.investigativemedia.com
