EPB1 Process for nickel and cobalt extraction direct reduction of garnierite ore for production of ferro

A method for the recovery of nickel and cobalt from nickel and cobalt containing laterite ores said method comprising a roasting feed ore in a reducing atmosphere in a rotary kiln to selectively reduce the nickel and cobalt wherein either no or less than 25 w/w reductant is added to the feed ore prior to roasting b leaching the reduced ore with an aerated ammoniacal ammonium carbonate The Past and the Future of Nickel Laterit Production of nickel from laterite ores has occurred for over 100 years as that amenable to pyrometallurgical processing saprolite garnierite involving drying calcining/reduction and electric furnace smelting Doniambo consisting of rotary dryers rotary kilns and electric
