The first cell or stage of the circuit is simulated using the mineral kdistribution obtained from the MFT testwork The model then calculates the kdistribution for both the concentrate and the tail based upon mass conservation of the flotation rate classes Figure 4 The new kdistributions are linked to the other cells downstream according3826
Reverse flotation is presently the most popular methodology for concentrating iron ore In reverse flotation the goal is to cause the gangue materials to move up and into the froth which is4568
