    摘要: Steel is made from iron ore by comminuting the ore and recovering a particle fraction which has a size less than 50 microns. The iron rich particles then are reduced to form iron or magnetite and are beneficiated by magnetic separation. The magnetite particles are further reduced to form small size iron particles. The iron powders produced by these processes are then processed by powder metallurgical techniques.
