Flotation is widely used to concentrate copper lead and zinc minerals which commonly accompany one another in their ores many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process this article was most recently revised and updated by chelsey parrottsheffer research editor
A comparison between a flotation mini pilot plant the industrial flotation circuit of minerao caraba was designed for an ore type copper grade and feed rate different from those that are mined nowadays this meant that the cells volume may not be optimised during the survey campaign the residence time of each stage was not measured instead they were calculated cell volume divided by
