本文探讨了梅克汉诺伯研究院开发研制的一种高效浮选柱,该机的各种部件最后安装到一特制的台架上。研究了其浮选槽深度、矿浆密度、精选区高度以及冲洗水流量在铜-镍矿精选中对选矿指标的影响。确定出,选矿槽高度5～7米、矿浆密度最佳时,回收率最高。基于这项研究开发的浮选柱,安装在选矿厂铜精矿的精选流程中,处理大量的硫化铜-锌矿石。充气设备是一组用弹力布包裹的多孔钢管,尾矿排料用一气动升降机实现。自动控制矿浆面。冲洗水通过一排安装在泡沫面下的喷水装置加入。文中分别给出了浮选柱对铜精矿进行第一和第二次精选的试验结果,证实该机技术指标得列提高,同时能耗和设备占地面积减少。本文还探讨了浮选柱模拟试验中的一些问题。
This article explores a highly efficient flotation column developed by the Mecken Hanover Institute, with the various components of the machine finally mounted on a special bench. The effects of flotation cell depth, pulp density, selected area height and flushing water flow on beneficiation index in copper-nickel ore concentrate were studied. Confirmed that the dressing tank height of 5 to 7 meters, the best pulp density, the highest recovery. The flotation column developed on the basis of this study is installed in a beneficiation process for concentrates of copper concentrates in the concentrator to treat large quantities of copper sulfide-zinc ores. The inflatable device is a group of porous steel tubes wrapped in elastic cloth, and the tailings discharge is realized by a pneumatic lift. Automatic control of pulp surface. Flushing water is fed through a row of sprinklers installed beneath the foam surface. The results of the first and second experiments of flotation column on copper concentrate are given respectively. The results show that the technical indexes of the machine have been improved, and the energy consumption and the equipment footprint decrease. This article also explored the flotation column simulation of some of the problems.
