摘　　要：铜陵硫酸渣研究结果表明，其含铁矿物主要是赤铁矿，约占６０％。脉石主要是石英约占２５％。赤铁矿和石英晶体不纯，含有少量其他元素。含铁矿物和脉石相互包裹及连生现象严重，影响选矿效果。硫酸渣中硫多数以可溶性硫酸盐存在，水溶脱硫率可达８０％以上。The observation results show that main iron mineral is hematite in the pyrite cinder of Tonglin, about 60% at pyrite cinder. Main gangue mineral is quartz, about 25% at pyrite cinder. Crystals of hematite and quartz are not pure, containing a few other elements.Iron minerals intergrowth with gangue minreals and inclusion with them each other, thus affecting separation efficiency.Sulphur in pyrite cinder occurred in form of dissoluble sulphate.After dissolved in water, it can be removed of more than 80%.
