New concept in flotation column design | SpringerLink
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. The bubbles disengage and rise to the top of the column to overflow into a concentrate launder, while the ...MEI Blog: Did Column Flotation Cells ever realise their ...May 14, 2010· We successfully installed and operated two separate column flotation cells back in the early 1990's in a nonmetallic processing operation. One unit was used in a rougher flotation application, removing iron mineral contaminants from a feldspar/quartz final product, while the other unit was used as a final cleaner flotation application for our primary product, a spodumene concentrate.Column Flotation Cell for fine materials | FLSmidthColumn Flotation Cells are an integral part of that circuit. Improved process economics with improved performance. Expanding on the historic supply of Pyramid™ flotation columns, our updated column cell offering includes optimised design elements focused on improved metallurgical performance and enhanced mechanical design.
