Abstract

The present invention discloses a flash smelting method for laterite-nickel ore, comprising: smelting laterite-nickel ore powder in a laterite-nickel ore smelting furnace in a reducing atmosphere to obtain alloys containing nickel-cobalt and iron and smelting slag, wherein the laterite nickel ore smelting furnace includes a vertical furnace body, a horizontal furnace bottom, a laterite-nickel ore nozzle, a furnace hearth nozzle and a smoke exhausting channel; the vertical furnace body has a suspending smelting chamber inside; the horizontal furnace bottom also has a smelting chamber; the lower part of the smelting chamber is formed with a furnace hearth; the laterite nickel ore nozzle is disposed on the top of the vertical furnace body so as to inject laterite-nickel ore powder, powdered coal, coke particles, solvent and oxygen gas into the suspending smelting chamber from the top of the vertical furnace body; the furnace hearth nozzle is disposed on the lateral wall of the horizontal furnace, wherein the temperature in the suspending smelting chamber is 800-1,200 oC, and the reducing atmosphere contains less than 85 pcnt of reducing gases. Therefore, the flash smelting method for the laterite-nickel ore can obviously save energy and enhance the nickel-cobalt content in the product.
