“…Hu et al [164] studied a biosurfactant, Sodium Lauroyl Methyl Isethionate (SLMI), which was employed for the first time in an ion flotation process to remove heavy metal ions (HMs) from simulated wastewater, and compared to the conventional surfactant Sodium Dodecyl Sulphate (SDS). Operational parameters such as surfactant concentration, flotation time, initial pH, and ionic strength were investigated.…”

The quest for sustainable mining processes has directed research towards environmentally friendly alternatives to conventional beneficiation practices, with biosurfactants emerging as a viable option due to their lower environmental impact. This study reviews the application of biosurfactants as bioreagents in mineral flotation, exploring their production, their mechanisms of action, and the sustainability benefits they offer. Methods include a decade-long text mining analysis of relevant literature, utilizing software tools like Zotero on platforms like Web of Science to extract and analyze data. The results underscore the growing interest in biosurfactants over the last ten years, highlighting their increasing relevance in industrial applications such as mineral flotation, where they replace synthetic surfactants. Particularly, biosurfactants have shown effectiveness in enhancing the froth flotation process, leading to more efficient mineral recovery while mitigating environmental harm. In conclusion, the adoption of biosurfactants in mineral processing not only aligns with sustainability goals but also demonstrates potential improvements in operational efficiency, offering a dual benefit of environmental protection and enhanced resource recovery.

The increasing prevalence of water contamination poses significant threats to environmental and public health. Traditional remediation methods often fall short in efficiency, sustainability, and cost-effectiveness, necessitating the exploration of alternative solutions. Biosurfactants, with their biodegradability, low toxicity, and high specificity, present a promising avenue for enhancing water remediation. However, the diverse types and complex mechanisms of biosurfactants require a thorough understanding to fully harness their potential. This review article addresses this need by compiling and synthesizing existing knowledge on biosurfactants to offer a detailed examination of their types, mechanisms, and applications in water remediation. By doing so, it aims to provide a valuable resource for researchers, practitioners, and policymakers to facilitate informed decision-making and foster the development of innovative, sustainable remediation strategies. The article also identifies current challenges and future research directions to guide efforts toward overcoming obstacles and optimize the use of biosurfactants in environmental applications.
