A Brief Review Of Pulp And Froth Rheology In Mineral Flotation
Froth flotation has been a stalwart in mineral beneficiation for than 100 years. During this time, and particularly in the past 20 30 years, there have been significant advances in the design and application of mechanical elements for flotation systems, e.g., new mechanisms, launders, larger cell volumes, better pumps, etc.Secondly, Flotation Columns achieve high froth levels that encourage draining and dampening of entrainment caused by high gas rates. Columns cells also differ in the way gas bubbles are generated. Air is either injected directly into the cell with use of internal spargers, or is carried into the cell through a high velocity recirculated stream.
