Microbial Fuel Cells for Power Generation by Treating Mine Tailings: Recent Advances and Emerging Trends

Microbial fuel cells (MFCs) have gained considerable attention in recent years due to their dual potential in waste treatment and clean energy production. In the field of mine tailings treatment, MFCs exhibit a unique advantage by integrating pollutant degradation with electricity generation, gradually emerging as a significant research focus. Based on 1321 relevant publications retrieved from the Web of Science Core Collection (WoSCC) from 2004 to 2024, this study employs bibliometric analysis to systematically explore the research status and future trends of MFCs in mine tailings treatment and power generation. The main research themes include (1) distinctive publication characteristics of MFC studies in the context of mine tailings treatment; (2) key information on leading countries, institutions, journals, and disciplines contributing to this field; and (3) a comprehensive summary of technological breakthroughs, emerging research hotspots, and future development directions of MFCs in mine tailings management. By thoroughly evaluating the existing body of research, this study provides valuable guidance for scholars new to the fields of MFCs and mine tailings treatment while offering insights into the technological advancements shaping the future of this domain.
