Prospects of high-velocity waterjet in mineral processing

The paper reflects the knowledge and the experience gathered at the High-Pressure Waterjet laboratories of the University of Cagliari, where waterjet technology is being studied and developed with special focus on mining, quarrying and ore beneficiation. The results so far achieved in various fields of mineral processing, like for instance desliming and comminution, oil agglomeration and flotation of ores and coal, are illustrated and discussed. Finally some preliminary conclusions are drawn about the prospects of industrial application
