Enhancing nickel grade and recovery with counter
All these issues combine negatively for nickel flotation, leading to the need for an excessive flotation cell footprint. Conventional flotation cells are highly constrained hydrodynamically. Firstly, for a given gas flux, G, the bubble surface flux, A = 6G/d 3,2, increases as the bubble size (defined by the Sauter mean, d 3,2) decreases.
