The present invention relates to recovery of metals in AOD cinder, which is compounded with reductant to form pellets or pressed blocks. They may be fed into induction furnace or inductive arc furnace for reducing directly to valuable elements Cr, Ni, etc. , or forming alloy or steel containing less Cr, Ni, Mn, etc. for further steel making. If they are put into arc furnace at the reduction period, Cr, Ni, Mn and other elements can be directly reduced to and dissolved in the liquid steel. Said invention is suitable for comprehensively utilizing the cinder of AOD, arc furnace and chromium iron smelting furnace to recover Cr, Ni and other metals and to produce other alloy.
