Abstract

A method and system for measuring properties of the pulp phase of a flotation cell are disclosed and includes at least partially submerging a probe inside the pulp phase of the flotation cell. The probe includes a camera, a light source and a viewing pane at an operative end of the probe. The viewing pane is positioned at an angle to the vertical and the camera is used to obtain intermittent images of the pulp phase through the viewing pane and under illumination from the light source.
