Abstract

The invention relates to the comprehensive utilization of laterite nickel ore, in particular to a method for treating laterite nickel ore through sodium reduction-roasting and separation, which comprises the steps of sodium reduction-roasting, chemical leaching, magnetic separation, melting separation, etc. It belongs to the field of metallurgical chemistry. The technical problem the Invention is to address is to comprehensively treat the laterite nickel ore by the method of sodium reduction-roasting and separation, especially to treat the high-iron, high-aluminum and low-nickel laterite nickel ore comprising TFe 55 pcnt -58 pcnt , Ah03 10 pcnt -12 pcnt , NiO 1 pcnt -1.5 pcnt , and unavoidable impurities. It can obtain the nickelferrite product containing 6 pcnt -1 0 pcnt of nickel, realize a yield of more than 80 pcnt of nickel, 54 pcnt or more of TF e grade in tailings, providing a new option for the treatment of high-aluminum laterite nickel ore.
