在阿尔玛雷克铜选矿厂的废弃尾矿中,50—60％铜、25～30％金损失于连生体中。大量贵金属与细粒级(-0.01—0.015毫米)一起流失,像类似阿尔玛雷克选矿厂这样大的选矿厂,矿浆流量大,设备大,磨矿机的处理量不断增大,随着开采露天采场的水平逐渐下降矿石硬度逐渐增大,金属损失于粗粒级中是不可避免的。主要问题是以最少的投资,从这些 In the waste tailings of the Almarek copper concentrator, 50-60% of copper and 25-30% of gold are lost in the metazoan. Large amounts of precious metals are lost with fine-grained grades (-0.01-0.015 mm), like large beneficiation plants like the Almare beneficiation plant, with large slurry flows, large equipment, and increased throughput of the mill, The level of open stope gradually decreases. The hardness of ore gradually increases. It is unavoidable that the loss of metal in the coarse-grained stage. The main problem is with minimal investment, from these
