Abstract

1,241,051. Flotation apparatus. BERGWERKSVERBAND G.m.b.H. 2 Aug., 1968 [5 Aug., 1967], No. 37079/68. Heading B2H. Apparatus for effecting the classification of particles by flotation comprises a cell a containing a series of zig-zag guide walls 21 to form a number of zig-zag ducts, diffusers 17 arranged below the cell a to conduct a suspension of solid concentrated particles in a finely dispersed mixture of air bubbles to the ducts and to reduce the entry speed of the suspension into the ducts and irregularly arcuate guide wall portions 45 arranged to produce eddy zones at the bends in the zig-zag ducts. As shown in Fig. 1b an aqueous suspension of a material passes from a rod mill to a stirring mixer where reagents are added and then to a pre-mixing chamber 4 which is provided with internal fittings 5 which distribute air into the suspension, a supply duct 6 opening into the chamber 4 and serving for the introduction of air and a mist of a foaming reagent formed by an atomising device 7. The suspension passes to a stirring device which includes an annular space 10 from which the suspension passes through a number of outlet openings 11. Coarse particles coming against the wall of the space 10 are passed by centrifugal force through ducts 12 for repeated treatment. The suspension passes through flexible ducts 16 to the diffusers 17, oversize particles being separated and fed back through hoses 18 into a dock 19 for further treatment. Each of the diffusers opens into the zig-zag ducts the zigzag walls 21 ending in the upper part of cell a at different levels so that the suspension is directed at right angles and moves over a sedimentation device 22 the tapering outlet ducts of which are connected by means of flexible pipes to an overflow 25 the height of which can be adjusted by a handwheel 21. Above the foam bed runs an endless band provided with blades 30 which remove the foam to a gutter 29.
