Iron tailings, dolomite (industrial grade, purity 98%) and a small amount of clay were combined in a N2 atmosphere at 1150 \u00b0C. X-ray fluorescence spectrometry (XRF), X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS) and a themogravimetric analysis (TGA) were performed and the specific surface area was analyzed to determine the strength and adsorption of the ceramsite. The results of the XRF showed that SiO2, CaO and Al2O3 were the main components of the ceramsite, with MgO and Fe2O3 also included. The results of the XRD and SEM-EDS showed that the ceramsite contained several kinds of minerals and was mainly composed of akermanite, gehlenite and diopside, and that the morphology of the internal structure of the ceramsite was mainly massive and contained a small number of particles. The ceramsite could be used in engineering practice to improve the mechanical properties of materials and meet the requirements of actual engineering for the strength of materials. The results of the specific surface area analysis showed that the inner structure of the ceramsite was compact and that there were no large voids. The voids were mainly medium and large, with a high stability and strong adsorption ability. The TGA results showed that the quality of the ceramsite samples will continue to increase within a certain range. According to the XRD experimental results and experimental conditions, it was speculated that in the part of the ore phase containing Al, Mg or Ca in the ceramsite, the elements underwent relatively complex chemical reactions with each other, resulting in the formation of an ore phase with a higher molecular weight. This research provides the basis of characterization and analysis for the preparation of high-adsorption ceramsite from iron tailings and promotes the high-value utilization of iron tailings for waste pollution control.<\/jats:p>","DOI":"10.3390\/molecules28052258","type":"journal-article","created":{"date-parts":[[2023,3,1]],"date-time":"2023-03-01T01:36:09Z","timestamp":1677634569000},"page":"2258","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Characterization of the Physical Chemistry Properties of Iron-Tailing-Based Ceramsite"],"prefix":"10.3390","volume":"28","author":[{"given":"Shaoguang","family":"Hua","sequence":"first","affiliation":[{"name":"School of Earth and Space Sciences, University of Science and Technology of China, Hefei 230026, China"},{"name":"Sinosteel Maanshan General Institute of Mining Research Co., Ltd., Maanshan City 243000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dun","family":"Wu","sequence":"additional","affiliation":[{"name":"Key Laboratory of Intelligent Underground Exploration, College of Civil Engineering, Anhui Jianzhu University, Hefei 230601, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jian","family":"Wu","sequence":"additional","affiliation":[{"name":"Key Laboratory of Intelligent Underground Exploration, College of Civil Engineering, Anhui Jianzhu University, Hefei 230601, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuqin","family":"Li","sequence":"additional","affiliation":[{"name":"Sinosteel Maanshan General Institute of Mining Research Co., Ltd., Maanshan City 243000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guijian","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Earth and Space Sciences, University of Science and Technology of China, Hefei 230026, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7184-8055","authenticated-orcid":false,"given":"Dejian","family":"Pei","sequence":"additional","affiliation":[{"name":"Sinosteel Maanshan General Institute of Mining Research Co., Ltd., Maanshan City 243000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"36","DOI":"10.1016\/j.conbuildmat.2014.07.075","article-title":"Characteristics of the fired bricks with low-silicon iron tailings","volume":"70","author":"Yang","year":"2014","journal-title":"Constr.
