A method for red mud and ferroalloy gas recovering includes carbonization of iron-containing sludge components in carbon-gas phase, at that previously sand fraction (50-) is isolated from the red mud, it is washed and after drying to a moisture content less than 20 % it is subjected to carburization at temperatures of 500- with ferroalloy gas, previously purified from sulphur compounds by the suspension of red mud. |
