OPTIMIZATION OF AIR-INJECTION SPARGERS FOR COLUMN FLOTATION APPLICATIONS Viviana Ramirez Coterio GENERAL AUDIENCE ABSTRACT 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.
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 ...

Column-like performance in a substantially smaller footprint. These compact, stackable units offer considerable savings for new installations and are ideal for expanding capacity in an existing plant. A new high-capacity flotation technology, the StackCell, has been developed as an alternative to both conventional and column flotation machines.
Little work has been done on the column flotation circuit to provide criterion for selection of optimum configuration although the combination of columns into existing flotation circuits are rapidly becoming common Meloy, 1983a, Meloy 1983b, Amelunxen, 1985, Subramanian et al., 1988, Huls et al., 1989.The general approach to such combinations has not been well defined and circuit selection is ...
The experience of pilot tests and commercial applications of column flotation for mineral processing and in waste water treatment circuits are also considered. This is the first book to consider column flotation design and operation experience and to present data on column parameters.
column flotation, covering pilot testing and scale-up, circuit design of selected applications, and instrumentation and control. We begin with a description of the key features and concepts of column flotation. KEY FEATURES AND CONCEPTS . A schematic of a flotation column is shown in Figure 1. Industrial flotation columns are 6-14 m

Flotation column; modelling; kinetic models INTRODUCTION A mathematical model of the column flotation process should, for given feed characteristics and design and operating variables, predict metallurgical performance. The model may also be used for design, control and optimisation of the colmrm flotation process.
The Eriez Flotation Division provides advanced engineering, metallurgical testing and innovative flotation technology for the mining and minerals processing industries. Strengths in process engineering, equipment design and fabrication position Eriez Flotation Divisio as a leader in minerals flotation systems around the world.
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.
flotation at laboratory scale, an investigation was carried, in order to design a (laboratory) column flotation cell at the Chair of Mineral Processing, which had to be based on the findings of an intense literature study. The final cell design was manufactured in co-operation with an Austrian provider for construction in plastics.
