立磨机在某硫精矿中回收锌的应用
|
摘要
从立磨机的结构和工作原理入手,介绍了立磨机在云南某大型硫精矿再磨提锌的应用情况。硫精矿入磨粒度-74μm占80%,产品粒度-45μm占90%,磨矿产品经三次精选达到含锌43%、含铅7. 5%,锌回收率55%、铅回收率18%的合格混合精矿,实现明显的经济效益。
Application of vertical mill in zinc recycling from a large-scale sulfur concentrate in Yunnan Province was introduced based on the structure and working principle of vertical mill. Sulfur concentrate with particle size of80% of-74 μm is added into vertical mill,the product size is of 90% of-45 μm. Qualified mixed concentrate,containing 43% zinc and 7. 5% lead and with recovery of zinc and lead of 55% and 18% respectively,is produced from grinding products by three stage cleaning. Significant economic benefits is achieved by this technology.
