An ore. is a rock that contains enough of a metal or a metal compound to make extracting the metal worthwhile. Most metals are extracted from ores found in the Earth''s crust.
In South Africa''s Bushveld complex and a limited number of other ore bodies, platinum group metals occur in sufficient quantities so as to make it cost efficient to extract these metals. At Russia''s Norilsk and Canada''s Sudbury deposits, the metal and other PGMs are extracted as byproducts .
6. Environmental Impact and Economics of Metal Ore Extraction and mining–quarrying other minerals. Aspects of this discussion applies to minimising the cost of production of any chemical product. What are the social, economic and environmental impacts of exploiting metal ores (mineral extraction), of using metals and of recycling metals – economic, sociological and environmental issues
Jul 06, 2016· Highly reactive metals such as aluminum, for example, can be isolated using an electric current in a technique known as electrolysis. Less reactive metals like iron can be extracted with reduction, where oxygen is removed from the ore through a reaction with carbon or carbon dioxide.
Extracting Surface Minerals. Surface mining is just what it sounds like ... To remove these minerals from the ... but also creates air pollution because gases that are created as byproducts (such ...
Mining is the extraction (removal) of minerals and metals from earth. Manganese, tantalum, cassiterite, copper, tin, nickel, bauxite (aluminum ore... SourceWatch: Environmental Impacts of Coal There are numerous damaging environmental impacts of coal that occur through its mining,...
Obtaining metals from metal oxides. Carbon is a nonmetal but it is more reactive than some metals. This means that some metals can be extracted. from their metal oxides using carbon.
Jul 06, 2018· Currently most attention is focused on mining TV sets, as there''s a massive backlog of these products, yet in the future the most common source for ewaste will be cell phones.
Mining Metals. Metals are often found as compounds in ores. An ore is a rock or mineral that has enough metal in it to make it worth extracting. Mining copper About 200 years ago the UK was an important world source of copper and tin and there were mines in Cornwall and Devon.
The actual mining of these ores declined for two decades beginning in the 1970s. Production fell by percent through the mid1990s. ... The production of miscellaneous metals is segregated into mining and metal refining ... from the same ores; separation of the individual metal products occurs in the smelting process...

There are four main mining methods: underground, open surface (pit), placer, and insitu mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.
Mining is the extraction of valuable minerals or other geological materials from the earth, usually from an orebody, lode, vein, seam, reef or placer deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.
From ore to metal. What are "ores"? An ore is any naturallyoccurring source of a metal that you can economically extract the metal from. Aluminium, for example, is the most common metal in the Earth''s crust, occurring in all sorts of minerals. However, it isn''t economically worthwhile to extract it from most of these .
Apr 03, 2015· The availability of these "byproduct" or "companion" metals is thus dependent not only on the mining production of their host metal(s) but also on whether the companion metals are recovered rather than being discarded without having been processed.

important metals of the PGMs. The other four, rhodium, ruthenium, iridium and osmium, are mined as byproducts of platinum and palladium. 58% of world PGM production takes place in South Africa1 not only for ore haulage but also to drive compressed air to and Russia accounts for a further 26%, most of this as a coproduct of nickel mining.
Nov 01, 2019· Skinner reported that extraction from common rocks is technically feasible but requires more energy than extraction from rich metal ores . Investigations by Harmsen et al. [25], Bardi [4], and Norgate and Jahanshahi [45] reinforced the position of Skinner regarding the increment of the specific energy for the extraction of metals from low ...
