Types of Extraction | S

Methods of extraction Many metals are found in the Earth's crust as or An ore is usually a compound of the metal mixed with impuriti When the metal is dug up, a method must be used to separate the metal from the rest of the ore This is called extracting the metal The method of extraction depends on how reactive the metal is The more reactive the metal, the more difficult it is to ....

Extraction Of Alkali Metals | Chemistry, Class 11, s

Oct 18, 2017· Alkali metals cannot be extracted from their ores by the usual methods of extraction of metals because of following difficulties: 1) Alkali metals are strong reducing agents and hence cannot be extracted by reduction of their oxides or chlorid 2) Alkali metals being highly electropositive cannot be displaced from the aqueous solution of their salts ,...
