Cenospheres are one of the most value added fractions of coal fly ash. They have a hollow
spherical structure and can be applied in many industrial applications, due to their superior …

Coal-fired power plants produce over 300 million tons of fly ash each year and this amount
still increases. Recently, this severe source of environmental contaminants is considered as …

The enhanced separation of valuable positively buoyant cenosphere particles from
negatively buoyant fly ash particles using an Inverted Reflux Classifier (IRC) was examined …

A new type of reflux classifier with a trapezoidal inclined channel has been designed and
used for pre-concentration of fine-grained low-grade oxidized antimony tailings. Theoretical …

This paper provides a detailed analysis of the separation of valuable cenospheres from
different fly ash feeds using the Inverted Reflux Classifier (IRC). Even though the IRC was …

The purpose of this work was to examine the novel concept of performing a wet dense
medium separation, utilising magnetite, on a fine (− 1.0 mm) coal feed in an inverted …

Cenospheres are hollow spherical particles formed as part of the fly ash waste of coal-fired
power stations. In a previous paper Kiani et al.(2015) investigated the recovery and the …

The combined mechanisms of Brownian diffusion and gravity settling are considered to
investigate the transport and deposition of particles in an inclined rectangular channel in the …

Cenospheres are one of the most valuable components found in the fly ash waste of coal
fired power stations, consisting of hollow, aluminosilicate spherical shells, offering very low …
