The Multipurpose Utilization of Taillings in Taozhong Mine, Maanshan Iron & Steel Company was investigated. The mineral processing flowsheet and size composition of the tailings were described. On the test results,the technical schemes of multipurpose utilization of tailings in Taochong Mine were advanced: classification of tailings, dewatering of coarse fractions with spiral classifiers, dewatering of fine fractions with ceramic filter and dewatering of slime fractions with pressure filter. The dewatering products can be used as raw material of cement industry. The u-tilization of tailings at Taochong Mine is favorable to economic operation and continual development. The no - tailings technique of mineral processing was realized at the plant.%对马钢桃冲矿业公司铁选矿尾矿综合利用进行了研究,介绍了选矿厂的选铁工艺流程和尾矿粒度组成.在试验研究的基础上,提出了该选矿厂尾矿利用技术方案,即对尾矿先进行分级,粗粒尾矿采用螺旋分级机进行重力脱水,浓密斗沉砂用陶瓷过滤机过滤脱水,矿泥采用快开式全自动隔膜压滤机进行脱水,脱水产品可用作生产水泥的原材料.结果表明,选矿厂尾矿利用不仅有利于矿业公司的生产经营和可持续发展,同时使选矿厂的无尾选矿工艺得以实现.
