US7157007B2 - Vertical gas induced flotation cell - Google . ,The bubbles migrate upwardly against the downward flow of oily water within the vessel and attach to oil droplets and/or oily coated solids augmenting the buoyancy thereof and thereby enhancing oily contaminant separation from water.
The Advantages of the Imhoflot G-Cell Pneumatic Flotation . ,The Barbrook flow sheet consists of crushing and milling followed by conventional roughing and scavenging tank flotation cells. Cleaning and recleaning of the rougher concentrate is by Imhoflot G-Cells. The flotation concentrate is then reground before the removal of carbon by gravity/cycloning. The carbon-free reground concentrate is then
Mixing and Hydrodynamics in Flotation Cells SpringerLink ,The flotation process is a complex interaction between the physicochemical characte- ristics of the species involved and the hydrodynamic and operating conditions in flotation cells. Efficient cell design requires knowledge about the power to be provided and the time to be spent in the cell by each one of the phases.
Flotation Process - an overview ScienceDirect Topics ,The most common examples of pneumatic cells are the column cell and the Jameson cell. As shown in Fig. 5.36 a flotation column is typically a tall vertical cylinder. It is fed with coal pulp at the top third of column. It has no mobile parts or agitators. Air bubbles are injected either through external or internal spargers at the bottom.
Flotation Eriez Flotation Division ,G.M. Callow patented the first pneumatic flotation cell which used air sparging through a porous bottom and horizontal slurry flow in 1914. The first countercurrent column flotation device was designed and tested by Town and Flynn in 1919.
US20130075338A1 - Induced-Gas Flotation Cell with Horizontal . ,An inlet device controls the momentum or velocity of the incoming water stream and rapidly converts it to horizontal flow prior to it encountering the first perforated baffle. The design of each baffle is such that the flow of water through each perforated baffle is a laminar or smooth flow without any change in direction.
The Empirical Prediction of Gas Dispersion Parameters on . ,The importance of bubble size in flotation cells has been appreciated since the very early days of froth flotation when noted that “it is essential that the air should be completely atomized in the pulp and not allowed to be distributed through the pulp in the form of comparatively large bubbles 9 ”.
