The unburned carbon content of fly ash from two different power stations was greatly reduced in two-stage laboratory flotation tests by employing a collector consisting of nonylphenol and either hexadecane or fuel oil together with methyl isobutinol (MIBC) as a frother. The tailings from the first stage were recleaned in the second stage.

fly ash to ~10% from an industrial fly ash sample having initial LOI value of ~ 15%. The effectiveness of the combination of screening and froth floatation (froth floatation after screening) gave encouraging results. A reduction in LOI to ~ 8% could be achieved using this combined process.

Fly ash is the main by-product of coal combustion. It is a solid, fine, and powdery material that consists of mainly non-combustible inorganic materials and unburned carbons. In 2009 over 375 Mt of fly ash, resulting from burning coal at power stations, was produced in China1. Pollution issues associated with fly ash are attracting more and more attention.
