A PROCESS FOR PRODUCTION OF NICKEL CONCENTRATE FROM CHROMITE OVERBURDEN/NICKELIFERROUS LATERITIC ORES

摘要

A process for the production of nickel concentrate from chromite overburden/nickel ferrous lateritic ores which comprises grinding chromite overburden and lateritic ores to a size in the range of 60 to 150 microns, granulating in the presence of water and powdered coke breeze, reducing the granulated material in a pan using down draft sinter in process at a temperature in the range and size reducing the resultant product to below 100 microns by known methods and separating the nickel concentrate by magnetic separation.
