Abstract
A method and system of maintaining substantially steady state conditions in a froth flotation operation. In the method an aqueous pulp of finely ground ore particles continuously flows into a flotation cell and is continuously aerated by admission of air wherein aqueous pulp of flotation concentrates substantially continuously overflow from the cell. The novel and improved method step comprises continuously monitoring the mass flow of flotation concentrates from the cell and, accordingly, varying the admission of aeration air into the pulp in the cell inversely with respect to the variations in the mass flow of the overflow to achieve steady state conditions in the cell. The system contemplated for continuously maintaining a substantially steady state condition in a froth flotation operation includes at least one froth flotation cell into which flows an aqueous pulp of finely ground ore particles, and aeration means fluidically communicating with the flotation cell for delivering air thereto. The improved system comprises aeration control means operatively connected to the cell for receiving overflows of pulp of flotation concentrates from the cell, and being operatively connected to the aeration means for controlling the aeration means by inversely varying the delivery of air to the froth flotation cell in response to variations in the mass flow rate of the overflow of pulp of flotation concentrates to attain steady state conditions.
