Conversion of recovered phosphorus tailings into high-value lightweight ceramic materials and evaluation of environmental safety
In recent years, the substantial production and underutilization of phosphorus tailings have prompted an intensified search for innovative strategies to mitigate their accumulation and the associated hazards they present. This investigation the utilization of phosphorus tailings as a raw material for the cost-effective production of lightweight ceramic materials using the foaming-gel casting method. The impact of the stirring process on lightweight ceramic materials was investigated, encompassing mineral composition, pore structure, properties, and environmental safety assessment. The investigation utilized slurry volumetric foaming rate, XRD, SEM, ICP-MS, and potential ecological risk index (RI) for analysis. The findings suggested that the lightweight ceramic material, obtained by stirring at 1300 rpm for 15 min, exhibited the densest structure and excellent properties. It had a porosity of 79.19 %, a bulk density of 0.59 g/cm3, and a compressive strength of 6.08 MPa. Besides, the leaching concentration and RI of lightweight ceramic materials complied with national (GB 8978–1996) and US EPA standards. This study aimed to enhance the sustainable production capacity of lightweight ceramic materials and offered data support for the value-added application and performance optimization of phosphorus tailings in the production of lightweight ceramic materials.
期刊介绍：
The Process Safety and Environmental Protection (PSEP) journal is a leading international publication that focuses on the publication of high-quality, original research papers in the field of engineering, specifically those related to the safety of industrial processes and environmental protection. The journal encourages submissions that present new developments in safety and environmental aspects, particularly those that show how research findings can be applied in process engineering design and practice.
PSEP is particularly interested in research that brings fresh perspectives to established engineering principles, identifies unsolved problems, or suggests directions for future research. The journal also values contributions that push the boundaries of traditional engineering and welcomes multidisciplinary papers.
PSEP's articles are abstracted and indexed by a range of databases and services, which helps to ensure that the journal's research is accessible and recognized in the academic and professional communities. These databases include ANTE, Chemical Abstracts, Chemical Hazards in Industry, Current Contents, Elsevier Engineering Information database, Pascal Francis, Web of Science, Scopus, Engineering Information Database EnCompass LIT (Elsevier), and INSPEC. This wide coverage facilitates the dissemination of the journal's content to a global audience interested in process safety and environmental engineering.
