摘要: Cobalt, nickel and/or radioactive cobalt are separated from an alloy containing elements belonging to the iron group or family in such a manner that the alloy is melted in a molten bath of tin, lead and/or an alloy thereof whose weight is more than ten times as heavy as the alloy and then silicon is added to the molten bath so that a Fe-Si phase floats up and is separated, concentrating the cobalt and nickel in said bath.

摘要: In a reactor, fine iron ore solids are made to descend through the fluidized bed of fine carbon bearing particles sustained within the reactor so that the fine iron ore solids may be reduced and simultaneously the reducing gas may be produced. The direct reduction efficiency may be considerably improved.
