The Investigation of Coke Breeze Demineralization on Temperature
The high ash coke breeze was leaching by two-stage chemical leaching. X-ray diffraction (XRD) and X-Ray Fluorescence (XRF) were employed to characterize the mineral phase and the element content respectably. More than 80% ash has been removed from the coke breeze by two-stage leaching. The removal of Si and Al was significantly affected by the temperature of alkali leaching. The mineral phase of the result coke breeze is similar to that of the raw ash except with cristobalite and sodium mica.
