WebThe results of electrolysis are the deposition of molten aluminum on the bottom of the cell and the evolution of carbon dioxide on the carbon anode. About 450 grams (1 pound) of carbon are consumed for every kilogram (2.2 pounds) of aluminum produced. About 2 kg of alumina are consumed for each kilogram of aluminum produced. WebThe Mineral cryolite. Cryolite is an unusual mineral with an interesting history. It was commercially mined in large quantities in Greenland since the mid-1800's, and this one locality produced almost the entire source of collectors specimen. Cryolite's economic importance was as a flux for the production of aluminum, but its significance ...
