A Look at Rare Earth Metals and Their Applications

04.12.2019· Rare earths are traded on the NYSE in the form of exchange-traded funds (ETFs) that represent a basket of supplier and mining stocks, as opposed to trading in the metals themselves. This is due to their rarity and price, as well as their almost strictly industrial consumption. Rare earth metals are not considered a good physical investment like precious metals, which hold low-tech intrinsic value.

Coal | National Geographic Society

22.12.2012· Bituminous coal is formed under more heat and pressure, and is 100 million to 300 million years old. It is named after the smithing coal, cannel coal, and coking coal. Smithing coal has very low ash content, and is ideal for forges, where metals are heated and shaped. Cannel coal was extensively used as a source of coal oil in the 19th century. Coal oil is made by heating cannel coal

Strip Mining an overview | ScienceDirect Topics

Mining activities and, in particular, strip mining of metal ores produce vast quantities of residues called mine spoils and mine tailings that may contain significant concentrations of metals (Fig. 14.1). Mine spoils or overburden consists of surface materials that do not contain the metal(s) of interest and that are therefore stockpiled at the surface, often resembling large “mesas.” Mine

Metal Simple English Wikipedia, the free encyclopedia

Metal is hard to pull apart (it has a high tensile strength) or smash (it has a high compressive strength). If you push on a long, thin piece of metal, it will bend, not break (it is elastic). Except for cesium, copper, and gold, metals have a neutral, silvery color. Not all metals have these properties. Mercury, for instance, is liquid at room temperature, Lead, is very soft, and heat and
