Best Air Sparging System for Column Flotation

Objective: Provide a low-maintenance, reliable means of generating bubbles and controlling bubble size for column flotation. Approach: Commercial sparger systems used in flotation columns to process minerals provide only limited means of controlling the size of bubbles generated and the rate of air injection. Generally, these limitations are a detriment to flotation

Air Sparging - an overview ScienceDirect Topics

The first pneumatic flotation cell, which used air sparging through a porous bottom and horizontal slurry flow, was patented in 1914 by Callow. The first countercurrent column flotation device was designed and tested by Town and Flynn in 1919. Cross-current pneumatic flotation machines were widely used in industry in the 1920s and 1930s, but were later replaced by the impeller-type flotation ...

Column Flotation - SGS

COLUMN FLOTATION. ABSTRACT. Industrial application of column flotation began in earnest in the early 1980’s, and is now accepted as a conventional application. For example, most of the world’s major copper producers use column flotation as the final stage of cleaning. In addition, the technology is common for final cleaning of zinc, lead and molybdenum sulfides, and for processing of iron ...

flotation columns should be considerably more fruitful, for the following reasons: 1. There is no mechanical agitation; 2. Close control is maintained over pulp rates and air rate; 3. Bubble size distribution is more uniform; 4. Particle entrainment into the froth is negligible; 5. Steady state laboratory testing is feasible. Recently, the first International Symposium on Column Flotation was ...

Column Flotation FLSmidth

Sparging system. FLSmidth columns feature venturi-style inline spargers. As the slurry is pumped into the slurry header, it distributes evenly between the spargers. The air header injects air individually into each sparger. Air is sheared into the slurry under dynamic pressure changes, providing high-intensity contacting with the bubbles. Compared to traditional jet-nozzle spargers, this ...

Development of a Novel Air Sparging Device

Development of a Novel Air Sparging Device Andrew Reid Hobert ABSTRACT Column flotation is commonly employed in the processing and recovery of fine mineral particles due to an increase in flotation selectivity unattainable using conventional flotation methods. Such an increase in selectivity is due to the employment of wash water, minimizing hydraulic entrainment of fine gangue particles, and ...

bubbles, which are injected at the bottom of the column. This air can be generated by internal or external sparging systems. It is common to separate the flotation column in two distinctive zones: the froth zone and the collection zone. In the collection zone, hydrophobic materials are collected by the air bubbles and transferred to the froth zone.

The column geometry is dictated by the maximum froth carrying capacity (which determines column diameter) and the bubble-particle attachment rate and particle retention time (which determines column length). The most important factor in the scale-up of an air sparging system is the ability to produce small bubbles in both laboratory and full-scale columns. Other factors, such as energy ...
