众所周知,当前在矿石加工过程中最明显的金属损失与选矿有关。正是在选矿过程中,达20％甚至更多的主要有用组分和大量伴生的贵重元素都损失掉了。在很多情况下,都不从矿石中回收黄铁矿和重晶石(回收一部分或者一直没回收)。
As we all know, the most obvious metal loss in ore processing is related to ore dressing. It is during the beneficiation process that up to 20% or more of the main useful components and a large number of accompanying valuable elements are lost. In many cases, neither pyrite nor barite are recovered from the ore (either in part or never recycled).
