Embodiments of the present invention provide a method for identifying sulfuric acid slag concentrate powder, which relates to the technical fields of sintering and iron making. The identification method of sulfuric acid slag concentrate powder includes: S1: drying and pulverizing the iron ore sample to obtain a mineral phase analysis sample; S2: inlaying the mineral phase analysis sample with transparent hot inlaid powder to form a mineral phase light sheet; S3: Grind, polish, and inspect the mineral phase light sheet to obtain a qualified light sheet; S4: Compare the qualified light sheet with the comparison map to determine whether it contains sulfuric acid slag concentrate powder. The identification method of the sulfuric acid slag concentrate powder can quickly prepare a qualified light sheet, it takes about 1 hour to prepare a qualified light sheet, and the success rate is over 95%. In the traditional method, it sometimes takes 1 day to prepare a sample, and the success rate is less than 50%; the spectrum can be quickly compared to determine whether it contains sulfuric acid slag concentrate powder, and the prepared qualified light sheet can be observed under a microscope , Compared with the spectrum, it can quickly judge whether it contains sulfuric acid slag concentrate powder. |
