摘　　要：探讨了黄铁矿在超细粉磨过程中的钝化问题 ,指出在搅拌磨制备FeS2 超细粉体时 ,当球料比 5∶1、矿浆浓度 40 %、磨矿时间 3h的条件下 ,加入助磨剂和缓蚀剂PZ1、PZ3 (5‰ )时 ,可获得磨矿细度≤ 3 .5 μm的FeS2 超细粉体 。Possivation of pyrite in ultra fine grinding is studied. It is pointed out that, in the preparation of ultra fine FeS 2 powder in a agitation mill at a 5∶1 ratio of ball to material, a 40% pulp density and a grinding time of 3 hours, the addition of grinding aid and corrosion retarder may help to obtain ultra fine FeS 2 powder with a fineness smaller than or equal to 3.5μm. The passivation mechanism of the corrosin retarder is analysed.
