Abstract

The present invention provides a laterite-nickel ore processing method for efficiently recovering nickel resources, which can save the early pellet processing cost and improve the recovery rate of nickel. The method comprises the following steps of: (1) laterite-nickel ore classification: crushing and screening the laterite-nickel ore; adding the reducing coal and fluxing agent into the laterite-nickel ore being larger than 2 mm and directly feeding the mixture into a rotary hearth furnace; adding the reducing coal and fluxing agent into the laterite-nickel ore being smaller than 2 mm and pressing the mixture into carbon-containing pellets by a pellet press; and drying the carbon-containing pellets and feeding the pellets into the rotary hearth furnace; (2) pre-reduction: feeding the carbon-containing pellets into a heat-accumulation type coal-based rotary hearth furnace, and performing high-temperature quick reduction in the furnace, the reduction temperature being from 1,200°C to 1,300°C, and the reduction time being from 20 min to 45 min; (3) melting: feeding the discharge product of the rotary hearth furnace into a melting device for slag-iron separation to produce nickel-iron alloy; and (4) levigation, sorting and melting: crushing the melting slag obtained by Step (3), performing ore grinding and magnetic separation, and returning the metal iron powder after the magnetic separation to the melting device in Step (3) for slag-iron separation to obtain the nickel-iron alloy.
