Design and ScaleUp Criteria for Column Flotation AusIMM

A reliable scaleup procedure for column flotation must address three important areas of column design, ie column geometry, sparging system and wash water distribution network. The column geometry is dictated by the maximum froth carrying capacity (which determines column diameter) and the bubbleparticle attachment rate and particle retention time (which determines column length).
