  • Froth Flotation Rate Limitations

    Physical Model of Flotation The first premise, based on visual observation, is that the froth volume or height above a float cell reaches a maximum very quickly and much faster than its removal This is borne out in batch experiments where each increment of cumulated recovery continues to decline with time once the froth is establishedAbstract Mineral carrying rates across the pulpfroth interface in the range of 1432 tph/m 2 and bubble surface coverage between 7 and 22 %, have been determined in large rougher flotation cells (100, 160 and 300 m 3)A model for estimating the carrying rate at the pulpfroth interface as a function of bubble surface coverage, bubble surface area flux and Sauter mean particle size of theOn the Carrying Capacity Limitation in Large Flotation Cellscells and details of this design will be discussed later in this article The top section of the disc connects to a drive shaft which in turn connects to the pulley/gearmotor drive assembly The impeller is located in the centre of the cell crosssection with its II/FLOTATION/Flotation Cell Design: Application of Fundamental Principles 1505Flotation Cell Design: Application of Fundamental
