  • Investigation Of The Reflux Classifier For Density

    Investigation Of The Reflux Classifier For Density

    Mar 16, 2017 Reflux Classifier technology is gaining popularity in coal processing applications across Africa because of its ability to easily handle varying feed conditions. Traditional technology cannot accommodate these feed variations resulting in recovery losses whereas the Reflux Classifier is a lot forgiving of solids feed rate variations.Combining reflux classification and froth flotation will give better results (coal recovery desulfurization) compared to using two stage froth flotation. This is because coal flotation is based on hydrophobicity of coal, while gravity separation takes advantage of the large difference in densities between coal and pyrite.
