How aluminium is extracted using electrolysis
Web6 de ago. de 2015 · Aluminium is extracted using electrolysis only! Electrolysis is the process where ionic substances are broken down into simpler substances using electricity. People also asked. WebWhat is the use of fluorspar in extraction of aluminium? Fluorspar is calcium fluoride having a chemical formula as CaF2. When fused cryolite and fluorspar are added to the aluminium oxide then the melting point of the mixture is decreased to 900∘Cand it also increases the mobility of the fused mixture which in turn increases the conductivity of the solution.
