What Is Alumina Production Problems And Mitigation
Mining and Extracting Alumina How Aluminum Is Made Mitigation Aluminum is the most abundant metal in the crust of the Earth—but it doesn’t exist in its pure form in nature. Bauxite ore first needs to be mined, then alumina is extracted from the bauxite, then the alumina is smelted into aluminum. Alumina is aluminum oxide (Al2O3). Its hardness, strength, and resistance to corrosion make it valuable as a coating to glass, ceramics, and aluminum itself....
