Yamana Gold
Yamana Gold Inc. is a Canadian company that owns and operates gold, silver and copper mines in Canada, Chile, Brazil and Argentina. Headquartered in Toronto, the company was founded in 1994 and became listed on the Toronto Stock Exchange in 1995, the New York Stock Exchange in 2007, and the London Stock Exchange in 2020.

The combined company was able to use Yamana's access to capital with Santa Elina development properties to bring the Chapada mine into production. From there the company combined with other TSX-listed companies RNC Gold, Desert Sun Mining, Viceroy Exploration, Northern Orion Resources, Meridian Gold, Osisko Mining and Extorre Gold Mines which each contributed either a producing mine or a development project that was able to come into commercial production.

Subsidiary
A subsidiary, subsidiary company or daughter company is a company owned or controlled by another company, which is called the parent company or holding company. Two or more subsidiaries that either belong to the same parent company or having a same management being substantially controlled by same entity/group are called sister companies. The subsidiary can be a company (usually with limited liability) and may be a government- or state-owned enterprise. They are a common feature of modern business life, and most multinational corporations organize their operations in this way. Examples of holding companies are Berkshire Hathaway, Jefferies Financial Group, The Walt Disney Company, Warner Bros. Discovery, or Citigroup; as well as more focused companies such as IBM, Xerox, and Microsoft. These, and others, organize their businesses into national and functional subsidiaries, often with multiple levels of subsidiaries. Details Subsidiaries are separate, distinct legal entities f ...

Smelting
Smelting is a process of applying heat to ore, to extract a base metal. It is a form of extractive metallurgy. It is used to extract many metals from their ores, including silver, iron, copper, and other base metals. Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind. The reducing agent is commonly a fossil fuel source of carbon, such as coke—or, in earlier times, charcoal. The oxygen in the ore binds to carbon at high temperatures due to the lower potential energy of the bonds in carbon dioxide (). Smelting most prominently takes place in a blast furnace to produce pig iron, which is converted into steel. The carbon source acts as a chemical reactant to remove oxygen from the ore, yielding the purified metal element as a product. The carbon source is oxidized in two stages. First, the carbon (C) combusts with oxygen (O2) in the air to produce carbon monoxide (CO). Second, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electrowinning
Electrowinning, also called electroextraction, is the electrodeposition of metals from their ores that have been put in solution via a process commonly referred to as leaching. Electrorefining uses a similar process to remove impurities from a metal. Both processes use electroplating on a large scale and are important techniques for the economical and straightforward purification of non-ferrous metals. The resulting metals are said to be ''electrowon''. In electrowinning, an electrical current is passed from an inert anode (oxidation, made out of lead (Pb)) through a ''leach'' solution containing the dissolved metal ions so that the metal is recovered as it is deposited in an electroplating process onto the cathode (reduction, stainless steel, aluminium (Al), titanium (Ti)). In electrorefining, the anode consists of the impure metal (e.g., copper) to be refined. The impure metallic anode is oxidized and the metal dissolves into solution. The metal ions migrate through the acidic ... [...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 ...

White Knight (business)
In business, a white knight is a friendly investor that acquires a corporation at a fair consideration with support from the corporation's board of directors and management. This may be during a period while it is facing a hostile acquisition from another potential acquirer (black knight) or it is facing bankruptcy. White knights are preferred by the board of directors (when directors are acting in good faith with regards to the interest of the corporation and its shareholders) and/or management as in most cases as they do not replace the current board or management with a new board, whereas, in most cases, a black knight will seek to replace the current board of directors and/or management with its new board reflective of its net interest in the corporation's equity. The first type, the white knight, refers to the friendly acquirer of a target firm in a hostile takeover attempt by another firm. The intent of the acquisition is to circumvent the takeover of the object of int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agnico Eagle Mines Limited
Agnico Eagle Mines Limited is a Canadian-based gold producer with operations in Canada, Finland and Mexico and exploration and development activities extending to the United States. Agnico Eagle has full exposure to higher gold prices consistent with its policy of no-forward gold sales. As of 2017, it has paid a cash dividend every year since 1983.
