WebThe fusion temperature of pure alumina is about 2000 ∘ C and at this temperature when electrolysis is carried out on the fused mass, the metal formed vaporizes, as the boiling point of aluminum is 1800 ∘ C. These difficulties are overcome by using a mixture containing alumina (Al 2O 3), cryolite (Na 3AlF 6), and fluorspar (CaF 2). WebApr 6, 2024 · So, we find that cryolite and fluorspar are halide ores. Hence, option B and C is correct. Additional Information: The process removal of undesired substances (gangue) from the ore is termed as concentration of ore. It involved many steps and choosing of these steps is based on the difference in physical properties metal present in the ore and ... 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 … spritz cookie press cookies
