马钢桃冲矿尾矿综合利用生产实践

The Production Practice of Multipurpose Utilization of Tailings in Taochong Mine,Maanshan Iron & Steel Company

摘要: 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。

Abstract: 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 product...
