Jun 07, 2019· Alumina is the important product for the extraction of aluminium. Electrolysis of alumina. Pure alumina is a bad conductor of electricity. It fuses at about 2900 degree Celsius. At this temperature, aluminium metal vaporizes off. These difficulties are removed by carrying out electrolysis of a mixture of alumina, cryolite, and fluorspar.

Introduction. Aluminum is too high in the electrochemical series (reactivity series) to extract it from its ore using carbon reduction. The temperatures needed are too high to be economic. Instead, it is extracted by electrolysis. The ore is first converted into pure aluminum oxide by the Bayer Process, and this is then electrolyzed in solution in molten cryolite another aluminum compound.
The low temperature molten salt method was used to extract potassium from Kfeldspar ore, and some related factors including mass ratio between NaNO 3, NaOH, H 2 O and Kfeldspar ore, particle size of Kfeldspar ore, reaction temperature and time were investigated, respectively. In addition, the optimum condition for this method was determined by a series of condition experiments.

Aluminum is extracted from aluminum oxide by a process called electrolysis. First of all, aluminum oxide needs to be in molten form to extract the aluminum ions. Aluminum oxide, however, has a high melting point. Therefore, aluminum oxide is dissolved in molten cryolite.
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 ...
