| 摘要 |
The present invention relates to equipment for a nickel recovery process, which unifies the pressure of a reducing furnace in the nickel recovery process, performs the reducing process in a stable way, and secures work stability by preventing an explosion of hydrogen. The equipment of the present invention comprises: a reducing furnace for performing hydrogen reduction of nickel ore; a quenching chamber for keeping the reduced ore in the status of a slurry; an extracting chamber for extracting nickel ions by performing an acid dissolution of the reduced ore slurry; and, a precipitating chamber for precipitating nickel by substituting the iron of the nickel ions and the reduced ore. The quenching chamber has a pressure-keeping means for keeping the internal pressure within the preset scope permitted by supply and discharge of gas in the quenching chamber. |
