The interaction of flash flotation with closed circuit grinding
The top discharge is of a lower pulp density (∼40–50% solids) compared to the bottom discharge (∼60–70% solids) and is sometimes bypassed to the mill discharge. The bottom discharge of the flash cell is used to feed the ball mill. In the cell, there is a distinct pulp density profile, where the density increases with depth in the cell.

Development of a grinding model based on flotation performance
Abstract. Usually, the concentration of minerals is carried out with a set of flotation and grinding units. Most of the modeling strategies for the flotation and grinding stages have followed separate developmental paths. This paper presents a strategy based on using flotation studies to model flotation and grinding via an integrated approach.
