Based on the databases of China National Knowledge Infrastructure (CNKI) and Web of Science, statistical analysis was conducted on journal papers regarding ammonia nitrogen treatment in weathered crust elution-deposited rare earth tailings from November 2009 to November 2024. CiteSpace was employed to perform visual analysis of the temporal distribution, authors, collaboration networks, research hotspots and research frontiers in this field. The research progress was systematically summarized in the form of knowledge maps, so as to provide research directions and theoretical support for soil ecological restoration and residual ammonia nitrogen pollution control in closed mining areas of weathered crust elution-deposited rare earth ores. The results show that the number of relevant publications exhibited an overall upward trend during the 15-year period. Most high-yield authors were from universities, with research dominated by team collaboration, and the vast majority of authors and institutions were from China. Although different studies had varied focuses, they all centered on ammonia nitrogen treatment and ecological governance of weathered crust elution-deposited rare earth tailings. Soil pollution prevention and ecological restoration have become research frontiers. Future research should strike a balance among treatment efficiency, remediation cost and green sustainable development.
