ABSTRACT The study involved the chemical and mineralogical analysis of actual tailings production from Lubin Concentrator Plant (KGHM Polska Miedz SA Group). KGHM Polska Miedz SA Group is the world’s leading company that mines and processes sediment-hosted stratiform copper deposits in SW Poland. From the beginning of copper ore mining, the problem of utilization and managing the deposited tailings has been discussed. Annually, all three concentrators produce above 30 million tons of flotation tailings. Lubin Concentrator Plant processes the most complex in upgradeability ore from the other two concentrators. The total loss of copper-bearing minerals in 0.020–0.071 mm size fraction was found to be 52%. The analysis of liberation showed that in fines (–0.020 mm) over 50% of sulfides is released while the amount of totally locked sulfides in the sample constitutes for 65%. The main cause of significant decline in the finest fractions should be attributed to inappropriate flotation time or too low collector dose. Insufficient liberation of sulfides in the coarser fractions can be a reason for the loss of copper in these fractions. The presented results of final tailings confirm the main cause of metal losses in tailings to be very complex mineral properties.

鲁宾选矿厂（波兰西南）层状铜矿浮选尾矿的化学和矿物分析

摘要 该研究涉及 Lubin 选矿厂 (KGHM Polska Miedz SA Group) 实际尾矿生产的化学和矿物学分析。KGHM Polska Miedz SA Group 是世界领先的公司，在波兰西南部开采和加工沉积层状铜矿床。从铜矿开采开始，就讨论了沉积尾矿的利用和管理问题。三个选矿厂年均生产浮选尾矿3000万吨以上。Lubin 选矿厂处理来自其他两个选矿厂的最复杂的可升级矿石。发现粒度为 0.020-0.071 毫米的含铜矿物的总损失为 52%。解放的分析表明，在罚款（–0. 020 mm) 超过 50% 的硫化物被释放，而样品中完全锁定的硫化物的量占 65%。最细部分显着下降的主要原因应归因于不适当的浮选时间或过低的捕收剂剂量。较粗馏分中硫化物的释放不足可能是这些馏分中铜损失的原因。最终尾矿的呈现结果证实了尾矿中金属损失的主要原因是非常复杂的矿物特性。
