Abstract

The present invention relates to a method for recovering ferronickel from nickel ore, comprising: a reduction step consisting of slurrying the reduced powders obtained by reducing nickel ore using a hydrogen-containing reducing gas, in an inert atmosphere, so as to prepare a slurry of reduced powder for leaching; a leaching step consisting of injecting sulfuric acid or hydrochloric acid into the slurry of reduced powder for leaching and dissolving and leaching nickel and iron by ions so as to obtain a solution containing nickel and iron ions; a leach residue removing step consisting of removing leach residue from the solution containing nickel and ferrous ions so as to obtain a leachate containing nickel and iron ions; and a precipitation step consisting of injecting the slurry in which the reduced powder obtained by reducing nickel ore using a hydrogen-containing reducing gas is contained in the leachate by 10 to 40 pcnt by weight with respect to the total weight of the reduced powder for precipitation and the reduced powder for leaching, into the solution containing nickel and iron ions so as to substitute the iron of the reduced powder for precipitation with the nickel in the solution containing nickel and iron ions and precipitate ferronickel.
