The use of power ultrasound in mining. L. Gaete-Garretón, in Power Ultrasonics, 2015 35.5.1 The flotation process. One of the most used processes to concentrate mineral from a mine is flotation. To perform a flotation process the mineral is finely ground (particle sizes between 50 and 150 μm), then the ground mineral is mixed with water in a container called a flotation cell.

A study of bubble-particle interactions in a column flotation process
2016年7月1日 : Bubble-particle interactions play an important role in flotation. This study examines the behaviour of bubble clusters in a turbulent flotation cell. Particularly, the bubble-particle interaction characteristics in flotation are investigated. The bubble size in a flotation column was measured using an Olympus i-SPEED 3 high-speed camera.

Column flotation simulation and control: An overview
2009年5月1日 Most of column flotation control issues are instrumentation matters, related to the lack of commercial sensors to monitor key process variables. Obviously, any linear control law is restricted to a certain range of operation, but it does not automatically preclude their use for processes exhibiting some nonlinear behaviour.
