General principles of extraction of metals
2019-10-22 In this method the ore is treated with a suitable chemical reagent which dissolves the ore leaving behind insoluble impurities. The ore is then recovered from the solution by a suitable chemical method. This is applied for extraction of aluminium from bauxite (Al2O3.2H2O). Bauxite is contaminated with iron (III) oxide
