Metals are found in ores combined with other elements. Electrolysis can be used to extract a more reactive metal from the ore. Bioleaching is used to extract small quantities of metals from mining
Most metals are extracted from ore. found in the Earth's crust. An ore is a rock that contains enough of a metal or a metal compound to make extracting the metal worthwhile
Obtaining metals from metal oxides. Carbon is a non-metal but it is more reactive than some metals. This means that some metals can be extracted. from their metal oxides using carbon
May 15, 2020 BBC BITESIZE REACTIVITY SERIES ACTIVITY. Metals more reactive than carbon, such as aluminium, are extracted by electrolysis, while metals less reactive than carbon, such as iron, may be extracted by reduction with carbon. It is used to produce white hot molten liquid iron in remote locations for welding. The image below shows what happens in a
Jul 22, 2019 Metals – Revision 1 – KS3 Chemistry – BBC Bitesize. However, copper can be extracted using carbon or hydrogen. A metal below hydrogen in the reactivity series will not react with dilute acids. Electrolysis is commonly gcxe to extract these metals and requires a lot of electric current energy to reduce them to extract the metal
