Detour Lake Mine
The Detour Lake mine property contains the mineral rights to a large area, approximately , in northeastern Ontario, near the Quebec border, approximately northeast of Cochrane, Ontario, or northeast of Timmins, Ontario. In 1979, rights-holder Amoco Canada Petroleum agreed with Dome Mines and Campbell Red Lake Mines Ltd. (which would both merge in 1987 with Placer Development Ltd. to form Placer Dome) to explore and develop the mineral resources. In 2019, Detour Gold – the former operating company of the mine – was acquired by Kirkland Lake Gold. After exploration and feasibility studies, by 1982, they estimated that a mine could be constructed at a cost of $143 million, consisting of an open pit for the first four years before transitioning to an underground mine to access a higher concentrations area at lower costs. The project included the construction of an all-weather road from Cochrane and a 45 megawatt transmission line, though they were mostly funded by the province. ...

Canada
Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's second-largest country by total area. Its southern and western border with the United States, stretching , is the world's longest binational land border. Canada's capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver. Indigenous peoples have continuously inhabited what is now Canada for thousands of years. Beginning in the 16th century, British and French expeditions explored and later settled along the Atlantic coast. As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces an ...

Cyanide Poisoning
Cyanide poisoning is poisoning that results from exposure to any of a number of forms of cyanide. Early symptoms include headache, dizziness, fast heart rate, shortness of breath, and vomiting. This phase may then be followed by seizures, slow heart rate, low blood pressure, loss of consciousness, and cardiac arrest. Onset of symptoms usually occurs within a few minutes. Some survivors have long-term neurological problems. Toxic cyanide-containing compounds include hydrogen cyanide gas and a number of cyanide salts. Poisoning is relatively common following breathing in smoke from a house fire. Other potential routes of exposure include workplaces involved in metal polishing, certain insecticides, the medication sodium nitroprusside, and certain seeds such as those of apples and apricots. Liquid forms of cyanide can be absorbed through the skin. Cyanide ions interfere with cellular respiration, resulting in the body's tissues being unable to use oxygen. Diagnosis is often diffi ...

Abitibi Gold Belt
The Abitibi gold belt is a region of Canada that extends from Wawa, Ontario to Val-d'Or, Quebec. Located within the mineral-rich Abitibi greenstone belt, the gold belt is an established gold mining district having produced over 100 mines, and 170 million ounces of gold since 1901. Timmins, a town founded in 1912 following the Porcupine Gold Rush and subsequent creation of the Hollinger Mines, McIntyre Mines and Dome Mine, which was one area in the region that experienced a gold rush, beginning in 1909. The Kerr Addison Mine in Virginiatown was at one time Canada's largest gold producing mine. Many of the towns readily acknowledge gold mining as part of their history, some being named after gold (Val d'Or means 'valley of gold', Kirkland Lake's nickname is 'the mile of gold'). One of Canada's 'large roadside attractions' is a 12-foot replica of a 1908 gold sovereign (nominally, one pound sterling) built to commemorate Canada's first gold coin which was made using gold from t ...

The Mining Journal (trade Magazine)
The ''Mining Journal'' covers global mining investment, finance, and business. Origins The ''Mining Journal'' was founded in 1835 in London by Henry English, a London stockbroker under the name of ''Mining Journal and Commercial Gazette''. In 1860 it was renamed to ''Mining Journal, Railway and Commercial Gazette'' and by 1910 it was called ''Mining Journal''. In the early days of ''Mining Journal'', then known as ''Mining Journal and Commercial Gazette'', it carried information on a range of subjects, from mines, machinery and metals prices, to news items and stories of general interest. The early issues also provided a glossary of mining terms, updated regularly, and noted all known mine accidents. In 1963, The Mining Journal Ltd took over rival publication '' Mining Magazine'', which had been founded in 1909 by Herbert Hoover, later to become President of the US, while he was a mining engineer then working in London. In 1935, as a centenary edition, it launched '' Minin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tailings Pond
In mining, tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction (gangue) of an ore. Tailings are different to overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed. The extraction of minerals from ore can be done two ways: placer mining, which uses water and gravity to concentrate the valuable minerals, or hard rock mining, which pulverizes the rock containing the ore and then relies on chemical reactions to concentrate the sought-after material. In the latter, the extraction of minerals from ore requires comminution, i.e., grinding the ore into fine particles to facilitate extraction of the target element(s). Because of this comminution, tailings consist of a slurry of fine particles, ranging from the size of a grain of sand to a few micrometres. Mine tailings are usually produced from the mill in slurry form, which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Criminal Negligence
In criminal law, criminal negligence is a surrogate state of mind required to constitute a ''conventional'' (as opposed to ''strictly liable'') offense. It is not, strictly speaking, a (Law Latin for "guilty mind") because it refers to an objective standard of behaviour expected of the defendant and does not refer to their mental state. Concept To constitute a crime, there must be an ''actus reus'' (Latin for "guilty act") accompanied by the ''mens rea'' (see concurrence). Negligence shows the least level of culpability, intention being the most serious, and recklessness being of intermediate seriousness, overlapping with gross negligence. The distinction between recklessness and criminal negligence lies in the presence or absence of foresight as to the prohibited consequences. Recklessness is usually described as a "malfeasance" where the defendant knowingly exposes another to the risk of injury. The fault lies in being willing to run the risk. But criminal negligence is a ... [...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] |
Ontario
Ontario ( ; ) is one of the thirteen provinces and territories of Canada.Ontario is located in the geographic eastern half of Canada, but it has historically and politically been considered to be part of Central Canada. Located in Central Canada, it is Canada's most populous province, with 38.3 percent of the country's population, and is the second-largest province by total area (after Quebec). Ontario is Canada's fourth-largest jurisdiction in total area when the territories of the Northwest Territories and Nunavut are included. It is home to the nation's capital city, Ottawa, and the nation's most populous city, Toronto, which is Ontario's provincial capital. Ontario is bordered by the province of Manitoba to the west, Hudson Bay and James Bay to the north, and Quebec to the east and northeast, and to the south by the U.S. states of (from west to east) Minnesota, Michigan, Ohio, Pennsylvania, and New York. Almost all of Ontario's border with the United States f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gold Cyanidation
Gold cyanidation (also known as the cyanide process or the MacArthur-Forrest process) is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex. It is the most commonly used leaching process for gold extraction. Cyanidation is also widely used in the extraction of silver, usually after froth flotation. Production of reagents for mineral processing to recover gold represents more than 70% of cyanide consumption globally. Other metals are recovered from the process include copper, zinc, and silver, but gold is the main driver of this technology. Due to the highly poisonous nature of cyanide, the process is controversial and its use is even banned in some parts of the world. Cyanide can be safely used in the gold mining industry. A key feature for safe use of cyanide is to ensure adequate pH control at an alkaline pH level above 10.5. At industrial scale, pH control is mainly achieved using lime, as an ...
