Abstract. Mineral carrying rates across the pulp-froth interface in the range of 1.4-3.2 tph/m 2 and bubble surface coverage between 7 and 22 %, have been determined in large rougher flotation cells (100, 160 and 300 m 3).A model for estimating the carrying rate at the pulp-froth interface as a function of bubble surface coverage, bubble surface …
