This study investigates the gas motion through the froth of a prototype bidimensional flotation cell.Using advanced video and image analysis techniques, surface velocity data obtained with a Visiofroth system were validated by comparing them with manual tracking results of bubble motion on the froth surface.Images for manual tracking were captured using a high-speed video camera.Additionally, discharge velocity profiles were analyzed as a function of froth height over the launder lip under different froth Crowder angles and superficial air rates.An increasing froth discharge velocity from the lip level to the top of the froth was observed.Air recovery was estimated using the velocity profile and compared with values derived from surface velocity estimation.Results indicated differences from 24% to 47% in air recovery when froth flow area at the lip was considered.However, both approaches displayed similar trends under varying JG and froth Crowder angles.Using top-of-froth velocity alongside the froth flow area at the Visiofroth location resulted in air recovery values closer to those obtained from the discharge velocity profile at the lip.
