| titleOfInvention | Method for removing impurity iron in gasified slag |
| abstract | The invention relates to a method for removing impurity iron in gasified slag, which sequentially comprises a high-temperature carbon thermal reduction process and a magnetic separation iron removal process, and the method utilizes the characteristics of the mineral phase structure and element composition of the gasified slag, takes carbon contained in the gasified slag as a reducing agent, and carries out high-efficiency dissociation and full reduction on iron elements in the gasified slag through staged temperature rise control, so that the mineral phase is converted into a stable mullite-quartz mineral phase, and the impurity iron is separated out through magnetic separation treatment, so that the method is quick and high-efficiency, does not relate to the use of toxic components in the whole process, does not discharge waste liquid, and has obvious economic and environmental benefits. |
