hydrometallurgy is concerned with processes involving aqueous solutions to extract metals from ores. the first step in the hydrometallurgical process is leaching, which involves dissolution of the valuable metals into the aqueous solution and or a suitable solvent. after the solution is separated from the ore solids, the extract is often subjected to various processes of purification and concentration before the valuable metal is recovered either in its metallic state or as a chemical compound. this may include precipitation, distill · text under ccbysa licenseextraction of metals all about minerals, ores ironsep 25, · it is simply the extraction of metals by electrolysis. electropositive metals like those of group 1 and group 2 are extracted through this process. extraction of metals is a complicated process and sometimes involves two or more processes to extract the pure element from its ore.extraction and refining of the platinum metalsbasic process for extraction of the platinum metals has remained essentially the same. rustenburg converter matte contains about 46 per cent of nickel and 28 per cent copper, together with some other base metals and sulphur. the platinum group metals, together with some g, total about fifty ounces toextraction of metals methods of extraction ofthe process of extracting metal ores buried deep underground is called mining. the metal ores are found in the earths crust in varying abundance. the extraction of metals from ores is what allows us to use the minerals in the ground! the ores are very different from the finished metalsheavy metals extraction by microemulsionsthe extraction/reextraction process by microemulsion consists of two stages. in the first one, the heavy metal ion present in the aqueous phase is extracted by the microemulsion. in a second step, the reextraction process occurs the microemulsion phase, rich in metal, is acidified and the metal is recovered in a new aqueous phase, with higherextraction of metals definition, factors occurencedec 06, · refining and purification of metal; oxidative refining; distillation; liquidation; electrolytic refining. distribution; types of metallurgy. hydrometallurgy this type of metal extraction involves use of aqueous solution. major steps in this procedure are as follows. leaching firstly metals are dissoluted in aqueous solutions or in a solvent.
