recovery, processing, and usage of wet-stored fly ash

recovery, processing, and usage of wet-stored fly ash

Jan 01, 2017 · Unlike most minerals produced by crushing and milling, fly ash is formed from a molten state and has a low surface charge. This, plus storage in fresh water with low conductivity and near neutral pH, produces a surface with low zeta (ζ) potential. As a result, there is a strong tendency for the ash to form flocs, which can significantly affect separation efficiency
