Abstract

L'invention concerne une machine et un procédé de flottation par dispersion d'air. Ladite machine comporte une série horizontale de cellules adjacentes de flottation ne comportant ni chicanes ni dispositifs mécaniques de distribution d'un gaz. Dans chaque cellule, un éjecteur est monté pour injecter un mélange à deux phases c'est-à-dire d'un gaz et d'un liquide, dans la cellule. Le liquide est pompé dans les éjecteurs de façon que la densité et l'énergie du mélange correspondent à un point d'injection situé dans la région I de la figure 3. Application à une machine et un procédé de flottation notamment pour la concentration des minerais, l'aération de liquides, le mélange de gaz et de liquides, etc.An air dispersion flotation machine and method is disclosed. Said machine comprises a horizontal series of adjacent flotation cells comprising neither baffles nor mechanical devices for distributing a gas. In each cell, an ejector is mounted to inject a two-phase mixture, that is to say of a gas and a liquid, into the cell. The liquid is pumped into the ejectors so that the density and energy of the mixture correspond to an injection point located in region I of FIG. 3. Application to a machine and a flotation process, in particular for the concentration of ores. , the aeration of liquids, the mixture of gases and liquids, etc.
