摘　　要：草分枝杆菌是一种无毒且在自然界广泛存在的微生物 ,它的细胞壁的组成和性质类似于常规赤铁矿捕收剂 ,可作为赤铁矿捕收剂使用。草分枝杆菌与常规赤铁矿捕收剂的对比试验表明 :草分枝杆菌对微细粒赤铁矿的捕收能力明显比常规赤铁矿捕收剂强 ,因此 ,它较常规赤铁矿捕收剂更适合作为微细粒赤铁矿的捕收剂使用。Mycobacterium phlei is a nonpoisonous microorganism which exists widely in nature. Its cell wall is similar to conventional collector's in composition and property. From the comparative tests, it is shown that mycobacterium phlei has a stronger collecting ability for fine hematite than the conventional collectors. Therefore, the former is much more suitable for collecting fine hematite than the latter.
