摘要： An apparatus for separation of solids in froth is presented. The apparatus includes: a housing (1), establishing a chamber (2) for flows of liquid and solid material and a froth bed (30) on the liquid; feeding means (14) for getting incoming material to be separated in contact with said froth bed (30); discharging means (6) for solid material near the bottom (12) of said housing (1); aerator means (24, 26) under the liquid surface (78) for creating bubbles and thus forming said bed of froth (30) and generating movement on the bed of froth (30); means for discharging froth from the housing (1) including at least a froth outlet (74). The apparatus is characterized by a surface (32) connected to said feeding means (14) so as to reduce the vertical speed component of the material being fed with the feeding means (14) from above said froth bed in and on to said froth bed (30).
