Coarse and fine particle flotation Mining EquipmentCavTube Sparging Eriez Flotation Division

COARSE AND FINE PARTICLE FLOTATION Mineral particle size is an important parameter in froth flotationIn Gaudin et al 1 showed that coarse and extremely fine particles are more difficult to recover by froth flotation as compared to intermediate size particlThis was approved by Morris 2 in Generally the flotation recovery and efficiency deteriorate rapidly when operating in the StackCell Flotation The StackCell uses a 2 stage system for particle collection and froth recovery Collection is optimized in a high shear single pass mixing canister and froth recovery is optimized in a quiescent flotation chamber
