摘要 本文介绍了作者采用氧化亚铁硫杆菌(T.f菌)对纯黄铁矿矿物进行微生物浮选的研究成果。研究结果表明 ,T.f.菌能在10min内迅速地吸附到黄铁矿表面 ,使黄铁矿表面由疏水变为亲水 ,丧失可浮性 ,因而T.f.菌是黄铁矿的一种有效的微生物抑制剂。并且指出 ,T.f.菌对黄铁矿的抑制是一种生物胶体的吸附作用。 In this paper,Thiobacillus ferrooxidans(i.e.T.ferrooxidans)was used in pyrite flotation.The experiments showed that T.ferrooxidans could adhere rapidly to pyrite in 10 minutes,transferring pyrite from hydrophobic to hydrophilic,which chanded the flotability of pyrite remarkably.So T.ferrooxidans is an effective microbial depressant for pyrite.The reason for T.ferrooxidans adhesion to pyrite is effect of microbial colloid.
