Ore Properties: large particle size and density of the feed material, the flotation machine should be prioritized for its suspension capacity, i.e., the slurry circulation performance in the tank.Flotation machines with shallow tanks and strong agitation are usually more suitable for this type of ore. Slurry Flow: large flotation machine has an advantage in processing a large amount of slurry.
