Kinetics of Iron Extraction from Coal Fly Ash by Hydrochloric Acid Leaching

Metals, 2018
Iron contained in coal fly ash of the Ekibastuz power station is distributed between magnetite and hematite. XRD data showed that ~80 wt % of iron is contained in magnetite and ~20 wt % in hematite. The leaching of iron from CFA by HCl was studied.
