Copper Mining In Chile
Chile is the world's largest producer of copper and has been so uninterruptedly since 1983. This activity provides a substantial part of the Chilean state's revenue: slightly less than 6% in 2020, with state-owned copper company Codelco alone generating 2.6% of state revenue. Mining of copper in Chile is done chiefly on giant low-grade porphyry copper deposits which are primarily mined by the following companies; Codelco, BHP, Antofagasta Minerals, Anglo American plc, Anglo American and Glencore. Together these companies stood for 83.6% of the copper output in Chile in 2019 and many copper mining companies are joint ventures involving one at least one of these. Medium-scale mining in Chile, which focuses mainly on copper, produced about 4.5% of the copper mined in the country from 2017 to 2021. Copper is also the main product of small-scale mining in Chile, with about 95% of small-scale miners working in copper mining. One estimate puts the number of active copper mines in Chile ...

Greenhouse Gases
Greenhouse gases (GHGs) are the gases in the atmosphere that raise the surface temperature of planets such as the Earth. Unlike other gases, greenhouse gases absorb the radiations that a planet emits, resulting in the greenhouse effect. The Earth is warmed by sunlight, causing its surface to radiate heat, which is then mostly absorbed by greenhouse gases. Without greenhouse gases in the atmosphere, the average temperature of Earth's surface would be about , rather than the present average of .Le Treut, H., R. Somerville, U. Cubasch, Y. Ding, C.

Copper Prices
Metal prices are the prices of metal as a commodity that are traded in bulk at a predefined purity or grade. Metal can be split into three major categories, precious metals, industrial metals and other metals. Iron ore Precious metals and industrial metals are priced by trading of those metals on commodities exchanges. Other metals are traded on demand and the buyers and sellers themselves set the price sometimes using third party companies that set a reference or indicative price. Precious metals include gold, silver, platinum and palladium and are normally priced by the ounce or gram. Industrial metals include aluminium alloy, aluminium, copper, lead, nickel, tin, zinc, cobolt, iron ore and Nasaac (North American special aluminium alloy) are exchange traded commodities and are normally priced by the metric ton. Other metals include bismuth, selenium, tellurium, and many others including rare earth metals are traded directly between suppliers and users. The London Metal Excha ...

Copper Ore
Copper is a chemical element; it has symbol Cu (from Latin ) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable, unalloyed metallic form. This means that copper is a native metal. This led to very early human use in several regions, from . Thousands of years later, it was the first metal to be smelted from sulfide ores, ; the first metal to be cast into a shape in a mold, ; and the first metal to be purposely alloyed with another metal, tin, to create bronze, ...

Ore Grade
Ore is natural rock or sediment that contains one or more valuable minerals, typically including metals, concentrated above background levels, and that is economically viable to mine and process. The grade of ore refers to the concentration of the desired material it contains. The value of the metals or minerals a rock contains must be weighed against the cost of extraction to determine whether it is of sufficiently high grade to be worth mining and is therefore considered an ore. A complex ore is one containing more than one valuable mineral. Minerals of interest are generally oxides, sulfides, silicates, or native metals such as copper or gold. Ore bodies are formed by a variety of geological processes generally referred to as ore genesis and can be classified based on their deposit type. Ore is extracted from the earth through mining and treated or refined, often via smelting, to extract the valuable metals or minerals. Some ores, depending on their composition, may pose ...

By-product
A by-product or byproduct is a secondary product derived from a production process, manufacturing process or chemical reaction; it is not the primary product or service being produced. A by-product can be useful and marketable or it can be considered waste: for example, bran, which is a byproduct of the mill (grinding), milling of wheat into refined flour, is sometimes composted or burned for disposal, but in other cases, it can be used as a nutritious ingredient in human food or animal feed. Gasoline was once a byproduct of oil refinery, oil refining that later became a desirable commercial Product (business), product as motor fuel. The plastic used in plastic shopping bags also started as a by-product of oil refining. By-products are sometimes called co-products to indicate that although they are secondary, they are desired products. For example, hides and leather may be called co-products of beef production. There is no strict distinction between by-products and co-products. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gold Mining In Chile
The amount of gold mined in Chile has fluctuated in the 2010–2023 period from a high of 50,852 kg in 2013 to a low of 30,907 kg in 2022. Also in the same period 36% to 72% of the gold produced annually in Chile was a by-product of copper mining. The share of medium and small-scale mining in gold production in Chile has dropped from an average of 45% for the 2003–2005 period to 9% in 2023. Most of the economically viable gold deposits in Chile belong to two types of deposits; high-sulfidation epithermal and porphyry type. The bulk of these deposits formed in the last 66 millions years (Cenozoic) in connection to magmatic activity in the Andes. Gold from iron oxide copper gold ore deposits (IOCG), from mesothermal deposits, or of Mesozoic age (formed 66 to 252 million years ago) may in some cases be recurrent geological features but lack often large concentrations to make them profitable. Almost all valuable non-placer gold in Chile occur in the northern half of the country an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Consejo Minero
Consejo Minero (lit. Mining Council) is a guild grouping large mining companies active in Chile. According to Consejo Minero in 2025 its companies produce 94% of Chile's copper, 96% of its iron, 90% of its silver and 63% of its gold and lithium. Its members are Anglo American, BHP, CMP, Minera Centinela, Codelco, Compañía Minera Doña Inés de Collahuasi, El Abra (owned by Freeport-McMoRan and Codelco), Minera Escondida, Freeport-McMoRan, Glencore, Gold Fields, KGHM, Kinross, Lundin Mining, Pampa Norte, Minera Los Pelambres, Rio Tinto, South32, Sociedad Química y Minera and Teck Resources. Prior to the joining of Compañía de Acero del Pacífico (CMP) in 2017 the guild lacked any company engaged in the production of iron.
