1 Froth Flotation – Fundamental Principles

2009-8-27  1 Froth Flotation – Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then carried to the surface and

Barry Wills' Blog: Did Column Flotation Cells ever

2010-5-14  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.

On-Line Fault Detection on a Pilot Flotation Column

2009-1-1  Multivariate statistical projection methods, such as Principal Component Analysis (PCA), have been proposed to effectively deal with these situations. In this work, a pilot flotation column is operated under distributed control of froth depth, gas hold up and bias, to experimentally collect operation data at steady state, to build a PCA model.
