It has been established that the extraction of aluminum from the rocks containing large amounts of alkali-soluble silicates and iron oxides can be processed by the acid-alkali method, except for the formation of wasted sludge. The carried out thermodynamic analysis showed the possibility of carrying out the process of reduction of a mixture of aluminum and iron sulphate salts with hydrogen. The optimal conditions for the reduction of aluminum and iron sulphates with hydrogen have been found with the production of S₂ and SO₂ and stub in the gas phase. Pure aluminum is obtained from stubby the Bayer method
