Research hotspot and trend of resource utilization of phosphorus tailings - based on Citespace and VOSviewer visualization

With the development and utilization of phosphorus resources, phosphorus tailings continue to pile up, which has become a serious problem that cannot be ignored, so the resource utilization of phosphorus tailings has extremely significant research significance. This study takes “phosphorus tailings” and “phosphate tailings” as keywords, 989 related research articles were selected from the Web of Science (WOS) database, and the research results were summarized. The research progress and research hotspots of phosphorus tailings resource utilization in the past 23 years were investigated. Citespace and VOSviewer were used to analyze the published literature in this research field. The results show that the research trend exhibits slow growth-fluctuating growth-rapid growth. The research organizations in this field present the form of independent research groups, among which there are more Chinese research teams. This paper systematically introduces the research hotspot of phosphorus tailings resource utilization, including the collaborative extraction of valuable elements from various solid wastes, and the collaborative preparation of functional materials from various solid wastes under the green closed cycle without by-product system. The future research focus is also put forward.
