Chromite Over Burden (COB) ore from Sukinda valley, Orissa is too lean in nickel concentration to be exploited for the extraction of nickel.The average nickel concentration in the COB are lies in the range of 0.4-0.6%. An acid leaching route at atmospheric prsssure has been developed for screening out silica as insoluble. Metal values in the leach liquor are retrieved as hydroxides by appropriate nia manoeuvring of pH. The metal hydroxides are converted to corresponding oxides by calcining at 900°C. The resu-ltant nickel content in the mixed oxide has been consist-ently found to be 1.6% and above. This product may be directly used as a starting material for the preparation of ferro- nickel
