How aluminium is extracted using electrolysis
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. Web26 de mar. de 2024 · Metals above carbon in the reactivity series must be extracted using electrolysis. Electrolysis can also be used to purify copper. Metals less reactive than carbon can be extracted from their ores by reduction using carbon, coke or charcoal. GCSE Chemistry - Electrolysis P2 - Electrolysis to Extract Metals From Oxides - …
