Extracting aluminium Aluminium is more reactive than carbon and it''s ore has a very high melting point (2050°C). This means aluminium cannot be extracted by reduction with carbon. Electrolysis is used to extract aluminium from its ore. In electrolysis, the ore is dissolved in a compound called cryolite (Na 3 AlF 6), which lowers the melting

Metal ores are mined from the earth''s crust, then metals are extracted from the ore. The form in which a metal exists in an ore depends on its chemical reactivity. The least reactive metals, such as gold, silver and copper, usually exist as native metals. They only need to undergo physical separation processes to be extracted.
