Abstract
Analysis of the structure of the froth in a flotation cell can be used to assess the performance of the cell. There is a close relationship between the bubble size distribution in the pulp and froth phases. Recent improvements in machine vision technology has made it possible to measure bubble size and stability in froth structure with a high degree of accuracy. These improved algorithms can provide a detailed map of flow patterns in the froths, which can give a significantly better idea of operating conditions in the flotation cell. The relationship between bubble size distribution in pulp and froth phases was investigated using a capillary tube system and digital image analysis.
