PROCESS AND DEVICE FOR NON- AGITATED FLOTATION OF SUBSTANCES WITH A LOW DEGREE OF HYDROPHOBY AND/ OR LOW STABILITY IN THE FOAM STRUCTURE

摘要

Process for non-agitated flotation of substances with a low degree of hydrophoby and/or low stability in the foam structure, in particular of salt mixtures, by gassing of a conditioned pulp in a separation chamber (1) with the aid of a gassing device (4), characterised in that the gassed pulp is thinned with the aid of a thinner pulp or with support liquid, and that this mixture is formed in the separation chamber into an enclosed vertical free jet (7a).
