据《加拿大冶金季刊》1991年报道,用电导率测定法测定浮选柱中的气体含量。气体含量是影响浮选柱分选性能的一个重要工作变量。它的在线测定可为操作人员提供控制空气流速的控制变量,同时提供连续监控空气分布器操作的方法。气体含量能根据沿浮选柱不同位置所收集的两个压力指示计算出。在水一空气体系中,这一计算简单且精确,因为沿浮选柱特定位置的液压仅仅受气体含量的影响。然而在矿浆-水体系中,该计 According to the Canadian Metallurgy Quarterly, reported in 1991, the gas content of the flotation column was determined by conductivity measurement. Gas content is an important working variable that affects the flotation column separation performance. Its on-line determination provides the operator with control variables to control air flow while providing a continuous method of monitoring air distributor operation. The gas content can be calculated from two pressure indications collected at different locations along the flotation column. In a water-air system, this calculation is simple and accurate because the hydraulic pressure at a particular location along the flotation column is only affected by the gas content. However, in the slurry - water system, the meter
