| titleOfInvention | Steel slag recovery method |
| abstract | The invention discloses a steel slag recovery method, which comprises the following steps: grinding the steel slag; reducing the ground steel slag at 600-800 deg.c with reducing gas; the reducing gas comprises hydrogen and optionally carbon dioxide; carburizing the reduced steel slag at 600-700 ℃ by using carburizing gas; the carburizing gas comprises carbon monoxide and optionally carbon dioxide and hydrogen; ball-milling the carburized steel slag in a carbon dioxide-containing atmosphere, and then carrying out magnetic separation to obtain concentrate and tailings; and introducing gas containing carbon dioxide into the tailings for conversion treatment to obtain tailings. According to the steel slag recovery method, the steel slag is used for preparing the iron carbide and eliminating the free calcium oxide in the steel slag, the electric furnace burden with high added value can be prepared, the free calcium oxide in the steel slag can be eliminated, and the comprehensive utilization degree of the steel slag is improved. |
