Best Air Sparging System for Column Flotation

24/02/2018 To permit greater control of the bubble size generated in the flotation column and to eliminate the counter-productive problems associated with the operation of current air sparger systems, the Bureau of Mines investigated alternative methods for generating bubbles. Based on the investigation, an external bubble generation system was designed, developed, and

High intensity air injection spargers the fundamental

19/12/2017 Although the first sparger design with automatic protection in case of air-supply failure was developed in the 1970s, this system suffered problems with wear. The concept of automatic closing was further developed in the 1990s. In 2016, Outotec introduced the SonicSparger Jet. With this technology, the optimal air pressure, airflow rate, and orifice size

The purpose of the sparging system is to distribute evenly the appropriate-sized bubbles near the bottom of the column. The sparging system is critical and must be designed taking into consideration

OPTIMIZATION OF AIR-INJECTION SPARGERS FOR COLUMN

In column flotation operations sparging devices generate small bubbles into the cell to carry the desired mineral to the surface for later recovery and processing. However, field studies suggest that air injector systems are not always optimized. Reasons contributing to the lack of optimization are: (i) ineffective internal design of the sparging system, and (ii) poor operation techniques

Role of Sparger Configuration in Determining Flotation

06/04/2021 Bubble size is crucial for determining flotation efficiency. Fine bubbles can be cost-effectively generated using a multi-orifice sparger with oscillatory air supply. Sparger configuration is defined by the orifice size, the plate thickness and the chamber volume. To date, the effect of sparger configuration on bubble size with oscillatory air supply is not clear yet.

Development of a Novel Air Sparging Device

sparger capable of resisting plugging and scaling was developed. Following the design, construction, and optimization of such a prototype, air holdup and flotation performance testing was completed to verify the viability of the sparger as a replacement to existing aerators.
