Method for smelting ferronickel or nismatte with laterite-nickel ore

The invention relates to a laterite nickel ore smelting process, in particular to a method for smelting ferronickel or nismatte with laterite-nickel ore, which comprises the following steps: crushing the laterite-nickel ore with a vertical mill until the particle size is less than 1mm, feeding the crushed laterite-nickel ore into various levels of suspension, drying and calcinating devices and a pre-reduction device in sequence, and guiding flue gas generated by the various levels of suspension, drying and calcinating devices into the vertical mill; spraying bituminous coal powder into the pre-reduction device for reduction and calcination of the materials in a suspension state, directly guiding the exhaust of the pre-reduction device into the the last level of drying and calcinating device, and smelting hot materials after pre-reduction in a DC furnace to produce the ferronickel or nismatte. The invention has the advantages of simple process, easy operation, low investment and high thermal efficiency, and can solve the problems of high energy consumption and high smelting cost in the traditional pyrometallurgy of the laterite-nickel ore.
