The basic module of the WEMCO 1+1 Inert Gas flotation system is a cell consisting of a single tank and mechanism. Several cells are bolted together to form a flotation process with feed, connection and discharge boxes as required. Pulp level in the tanks is controlled by automatically operated dart valves in the connection and discharge boxes.
We use this system to measure froth velocity and to infer the froth grade, which then allows us to quantify the mass flow rate of each flotation cell and make decisions on which cell levels should be increased or decreased based on current grade/recovery curve and the exact behaviour of each individually optimised flotation cell.
2012-10-1 · Abstract. Machine vision has been proposed as an ideal non-intrusive instrument to obtain meaningful information relating to the performance of the froth phase of flotation for the purposes of process control. Many attempts have been made to use machine vision to predict performance factors such as mass recovery rate and concentrate grade.
