Abstract The collision of fine mineral particles with a bubble in a countercurrent flow regime has been modeled to predict the collision efficiency between fine mineral particles and a single bubble in a flotation column. Surface forces (DLVO forces as well as non-DLVO forces) are ignored in the collision process. The complete Navier-Stokes equations are resolved to achieve a finer angular grid for the numerical solution of a collision angle which is a function of the density of the particles represented by the Galileo number (Ga) and of the Reynolds number of bubbles in a countercurrent flow regime (Re). The collision efficiency given is a function of the diameters of both the particles and the bubble, and to both Ga and Re, and to the bubble slip velocity and terminal settling velocity of the particles. The value of the collision efficiency has been determined experimentally: the agreement between the theoretical predictions and the measured values is good.
