Concentrate flow was obtained by making tailing flows smaller than feed flows. Hence, part of the feed water was carried up within bubble wakes. No pulp/froth interface was established. A high recovery was obtained in a 2 m collection zone column. The recovery reached >80% with a grade of ∼90%. It was found that the recovery depended on the value of the difference between the feed flow and tailing flow. In addition, a straight line between the surface velocity of mineral and the recovery was found. It appears that a maximum capacity of solid is ∼10 g min−1 cm−2.
