METHOD TO PROCESS OXIDIZED NICKEL-COBALT ORES Russian patent published in 2003 - IPC

Abstract RU 2202637 C2

FIELD: non- ferrous metallurgy. SUBSTANCE: method can find use in processing of nickel-cobalt ores and products of their beneficiation. Method includes reducing-magnetizing sintering of ore in atmosphere of live steam at temperature of 480-600 C with use of carbamide in the capacity of reducing agent or any other organic substance showing increased boiling temperature and containing no sulfur. Any known technology ( hydrometallurgy or electrostatic separation ) can be employed to recover nickel and cobalt from magnetic fraction. EFFECT: simplified technology, reduced energy consumption, improved ecological situation. 2 tbl
