IMPROVEMENT TO THE SEPARATION AND RECOVERY OF SOLIDS FROM LIQUIDS CONTAINING THEM AND USING THE IONIC FLOTATION PROCESS, AND MEANS FOR IMPLEMENTING SUCH IMPROVEMENT

摘要

Improvement to the separation and recovery of solids from liquids containing them, and using a ionic flotation process, implementing an installation characterized in that it comprises at least a vat (1) for pretreating the solution to be treated for the insolubilization of the solid to be recovered and the formation of a suspension maintained under stirring conditions (stirrer 2), at least a flotation cell (5) supplied with said suspension, at least a device (4) provided between said vat (1) and said flotation cell (5) adapted to generate within the cell a rising non-turbulent stream intended to convey the desired solid towards the surface of said suspension while maintaining at said surface a calm area for the accumulation of said solid and at least one means for the recovery of said solid (6-7).
