摘要
本文介绍了在实验室条件下，对包壳矿煤球团进行的烧结法还原焙烧、磨矿、选矿等试验过程．经多次试验．找出了合适的焙烧制度和磨矿粒度，最终选别出了品位＞90％的可代替废钢作炼钢原料的铁粉．
The laboratory investigation of reduction roasting, fine grinding and gravity concentration of shell ore - coal pellet were conducted. Through many times experiment, the adaptive induration scheme and liberation grind were found and a kind of iron fine (TFe >90% ) which instead of wast steel as steelmaking meaterials was obtainted.
