What Are Column Flotation Cells? indres

06022019· The other type of flotation cells is a column cell Column cells are tall round tanks that use compressed air to create air bubbles via spargers or cavitation tubes These cells are used to perform mineral separations Column cells do not use mechanical agitation (impellers) Mixing is achieved by the turbulence provided by the rising bubblesColumn Flotation Cells are an integral part of that circuit Expanding on the historic supply of Pyramid™ flotation columns, our modernised column cell offering includes design elements focused on improved metallurgical performance and enhanced mechanical design This approach considers the main elements of column flotation: froth washingColumn Flotation Cell
