METHODS FOR CONCENTRATING AND RECOVERING FERRO NICKEL FROM NICKEL CONTAINING RAW MATERIAL, METHODS FOR RECOVERING NICKEL FROM THE CONCENTRATED FERRO NICKEL AND REUSING METHOD OF FE CONTAINING SOLUTION WASTED FROM THE METHODS

摘要

PURPOSE: A method for concentrating and collecting ferronickel from a nickel-containing material, a method for collecting nickel from the concentrated ferronickel, and a method for recycling iron-containing solution produced in the method are provided to effectively collect nickel from concentrated ferronickel by separately collecting nickel and iron from mineral with a low nickel level. CONSTITUTION: A method for concentrating and collecting ferronickel from a nickel-containing material comprises the steps of: reducing a material including nickel and iron and adding water to make slurry, adding hydrochloric acid or sulfuric acid to the slurry, filtering solid powder including ferronickel and removing iron solution from the treated solution, and making the solid powder into slurry and mixing the slurry with the reduced material.
