Advanced study on the extraction of Nickel from its ores
saprolite. The ore is dried and nickel is selectively reduced (together with cobalt and some iron) to metallic nickel at ~ 700°C. The metallics are extracted by leaching in an ammoniacal solution. Recovery of nickel and cobalt decreases with the increasing amount of saprolite since nickel and cobalt are locked in a silicate matrix and are
