extraction calciumit is always found as a compound such as, in limestone, chalk and marble. thus, it does not have a specific ore that it is extracted from. the process ofthe process of metal extraction from ore term paperthe process of metal extraction from ore metals are produced when metal oxides have their oxygen removed. the process of metal extraction from ore is dependent on the reactivity of the metal. highly reactive metals are extracted by electrolysis. in order of decreasing reactivity, these metals are potassium, sodium, calcium, magnesium and aluminum.us2874039a extraction of scandium from its ores googleus2874039a us515251a us51525155a us2874039a us 2874039 a us2874039 a us 2874039a us 515251 a us515251 a us 515251a us 51525155 a us51525155 a us 51525155a us 2874039 a us2874039 a us 2874039a authority us united states prior art keywords scandium zone chloride chlorides mixture prior art date 19540617 legal status (the legal status is an assumption and is notmethod of extraction used to obtain calcium from its ore9.8/10(888)how is calcium extracted from its ore? restaurantnormanjun 26, 2019· how is calcium extracted from its ore? in order to isolate pure calcium, it must be extracted through electrolysis, a technique that uses a direct electricalhow is calcium extracted from its ore? answersqhow is calcium extracted from its ore?aits extractedsee more on answerschemistry form three topic 8 extractions of metalsfeb 17, 2021· extract ores containing minerals, a chemical reaction must be used to separate the metal from other elements. the choice of the best method for extraction of a metal from its ore depends on the chemical reactivity of the metal to be extracted. most ores contain metal oxides. to extract the metal, oxygen must be removed from it. this reaction ifextracting metals how are metals with differentan ore. is a rock that contains enough of a metal or a metal compound to make extracting. the metal worthwhile, eg either low grade ores contain a small
