Raw material for reduction aluminum production is alumina, molecular formula is Al2O3, it is a white micro powder refined from ore, the quality and purity of alumina as basic in reduction cells play crucial roll. (Transportation, ware housing, process problem…) may cause impurity and contaminate the alumina, which have negative impact on the purity of aluminum. Some of above mentioned problems are inevitable and the proper methods should be applied for removing the impurities from alumina
