2018-1-15  In a laboratory batch flotation cell, the froth depth is limited to 2 cm and a froth of a greater height would overflow into the concentrate. This indicates that the increase in water recovery resultant from an increase in Eh may be causing the entrained particles to proceed to the concentrate before they can drain back into the pulp. 3.1.
