REDESIGN OF INDUSTRIAL COLUMN FLOTATION …

A column cell consists of a vertical column into which air is added at the bottom using spargers (no impeller). Columns usually use wash water to prevent fine clays from being entrained into the clean coal froth. Gas compressors are usually required to provide the air flow and energy for air dispersion. A column cell is usually a stand-alone ...

New concept in flotation column design | Semantic Scholar

A form of column flotation cell is described in which the contact between the feed and the air stream is made in a mixing device at the top of a vertical downcomer. The air-liquid mixture flows downward to discharge into a shallow pool of pulp in the bottom of a short cylindrical column. The bubbles disengage and rise to the top of the column to overflow …
