【 摘 要 】

Influence of height of foam on salt flotation of copper-bearing shale, having different Cu and organic carbon contents, was investigated. It was found that the yield of flotation of copper-bearing shale in the presence of NaCl is directly dependent on the content of organic carbon and height of foam produced during flotation. It has been shown that the height of flotation froth h depends on type of shale, and its variation can be described by formula h/h max = 1/(t+1) n , where t is the time of flotation and n is a constant.
