粗精矿预先分级产品分别处理的新工艺探讨

A NEW TECHNOLOGY DISCUSSION ABOUT VIRGIN FINISHED ORE PRE-CLASSIFICATION PRODUCT BE SEPARATELY TREATED

在不降低铜及伴生元素回收率的前提下提高铜精矿品位 ,是江铜面临的攻关课题 ,根据德兴铜矿选矿多年的生产实践及试验研究 ,提出采用一段粗精矿预先分级溢流、沉砂分别选别的新工艺及其它工艺措施 。

Raising copper concentrate grade is JiangXi Copper Company's key issue without Lowering copper and associated element's recovery rate. According to productive practice and experimentat research of Dexing Copper Mine ore dressing in several years. A new technology about pre-classification overflow of one piece of virgin finished ore and sedimentation separately treated is submitted, other technology measure is also submitted, it means to an end that it can raise finished ore grade and associated element's recovery rate.
