Column Flotation - SGS

Flotation columns are also practical, as their footprint is small and a proper height will allow for effective multi-stages separation (Moon and Sirois, 1983), akin to the operation of a distillation column with counter-current flow of coal- carrying bubbles up and ash-laden water down. Addition of wash water at the top of the column results in ...

A laboratory scale jet flotation column system was designed and air inflation for flotation column was provided by jet aerator with a chamber. In order to understand interior flow field distribution of jet aerator and flotation column, two-phase turbulent flow model was established by use of commercial computational fluid dynamics (CFD) software FLUENT 6.3.26.

Flotation columns: Getting the most from fine ores - Outotec

Basic Idea Flotation column cells are flotation act as three phase settlers where particles move downwards in a hindered settling environment counter-current to a flux of rising air bubbles that are generated by spargers located near the bottom of the cell. The sparger technology is an important design choice, and allows the user to optimize the performance based on the feed characteristics ...

1 Froth Flotation – Fundamental Principles

Column flotation cells have become the most popular separation device designed for industrial applications requiring the concentration of wanted or unwanted mineral from the rest material in a pulp. To achieve separation, an air sparging device is required to produce bubbles in the flotation cell. In column flotation operations sparging
