Process of agglomeration of iron ores with a total suppression of polluting emissions towards the atmosphere

The procedure, in which a charge of iron ore mixed with solid fuel is deposited on a belt (1), preferably in the form of an endless moving grid, set alight by means of an ignition hood (4) and the gases drawn through the charge and recycled, differs by drying a non-recycled portion of the gases coll...

description The procedure, in which a charge of iron ore mixed with solid fuel is deposited on a belt (1), preferably in the form of an endless moving grid, set alight by means of an ignition hood (4) and the gases drawn through the charge and recycled, differs by drying a non-recycled portion of the gases collected beneath the charge, extracting the carbon dioxide and injecting the remaining gas flow into a reducing fusion reactor such as a blast furnace. This gas flow contains at least 50, and preferably 90 per cent oxygen.
