Continuous measurement of the froth height, provided as feedback to the control loop for the inlet "dart valve," allows a notation cell to maintain constant overflowing of froth to the launder, even when the orebody type may produce variations to frothing consistency. Relative density data can be used to control density through a feedback loop, regulating forced airflow into the flotation cell, Air input is currently largely controlled manually by onsite operators.
