浮选柱的发展是选矿领域几十年来的一项重大成就。浮选柱的高效率使作业时间减少、精选段数减少及循环负荷减少,使过程更加稳定可靠。当前一种独特的多段浮选柱装置业已研制完成。和单段的浮选柱相比,多段浮选柱装置具有许多鲜明的优点,能提供分离不同可浮性颗粒最有利的条件。为了获得特殊的流体动力学,在各段浮选柱中安装了充气装置。因而可根据矿物的可浮性来调节操作变量。在多段浮选柱中建立起了物料-设备的反馈信息,依据待浮选矿物的特性来选择最佳操作条件。这些概念即为研究多段浮选柱装置的设计基础。第一台多段浮选柱设
The development of flotation columns is a major achievement in the area of mineral processing for decades. Flotation column of high efficiency to reduce operating time, reduce the number of segments and reduce the cycle load, the process more stable and reliable. A unique multi-stage flotation column unit has been developed. In contrast to single-stage flotation columns, the multistage flotation column unit has many distinct advantages that provide the most advantageous conditions for separating different flotation particles. In order to obtain special hydrodynamics, an inflator is installed in each section of the flotation column. Thus manipulated variables can be adjusted according to the flotability of the minerals. Material-equipment feedback is established in the multistage flotation column and the best operating conditions are selected based on the characteristics of the minerals to be flotated. These concepts are the basis for the design of multistage flotation column plants. The first multi-stage flotation column set
