Method for smelting aluminum ore by carbon thermal reduction and non-ferrous metal smelting furnace therefor

The invention relates to a method for reducing and smelting aluminum ore by using carbon heat and the nonferrous metal smelting furnace of the smelting aluminum ore, which belongs to the technical field of the metal ore smelting. The method is characterized in that the pellet preparation comprises the steps that, coal gangue, bauxite and waste fiber are crushed and levigated; binding agent is prepared; the powder or the short grained coal gangue and the bauxite are mixed uniformly with the fiber micro-particle in proportion; the mixture is made into the pellet by the binding agent; the pellet and the coke are put into smelting furnace alternatively. The smelting furnace is composed of a multi-hole melting zone connected with an air inlet pipe, a high temperature resistant furnace lining, a cooling atomizing sleeve, a pair of heating electrodes inserted at both sides of the smelting furnace bottom towards the centre and a cracking water burning chamber. After the method is applied, the polluted environment wit
