Overview of the different methods of extraction of metals

Aug 16 2009Overview of the different methods of extraction of metals Metals are found in the Earth either as compounds or in the case of very unreactive metals as the crust of the uncombined element The rock that contains the metal is called an ore Common metal ores include bauxite (aluminium oxide) haematite (iron oxide) zinc blende (zinc sulphide) galena (lead sulphide) and cinnabar (mercury Get price


New methods of mineral extraction

Alongside extracting minerals from lumps of rock and capturing stones directly at the station this mode of transportation will become more popular since extraction inside meteorites will be infeasible due to their small dimensions while the capture of materials by space mining stations will be hindered conversely by their large dimensions Get price

Inductively Coupled Plasma The Future of Heavy Metals Testing

success of the method The sample can be dissolved in a solvent typically a dilute acid but water or an organic solvent may also be used Typically dilute nitric acid or hydrochloric acid is used to eliminate interference but other acids may be used if necessary If the sample is not soluble or the solution clogs the nebulizer anGet price


A Comparison of the Methods of Heavy Mineral Separation

Methods and apparatus used in the isolation of heavy minerals vary considerably with different workers and this lack of uniformity obviously reduces the value of the conclusions in a branch of petrology in which quantitative data are essential Get price



it entails the disintegration of grains rich in other mineral inclusions and air bubbles leaving behind the more resis-tant grains For feldspars the removal of the mineralogi-cally less stable grains (e g plagioclase) and altered (cerici-tised) grains results in a K-rich and resilient feldspar frac-tion Get price
