本文介绍智利最大钢-钼选矿厂的柱浮选实践情况。这些选矿厂在新系列和现有系列中，逐步选用柱浮选流程代替多段精选流程。在选定的的选矿厂中，采用了包括柱浮选工艺流程，对按比例放大的方法和过程控制也做了介绍。
This article describes the column flotation practice in Chile’s largest steel-molybdenum concentrator. In the new series and the existing series, these concentrators have gradually adopted column flotation instead of multi-stage selection. In the selected concentrator, a column flotation process was used, including a scaled up method and process control.
