Abstract
Due to their environmental benefits and rich interfacial and colloidal properties, biosurfactants show promise as a platform for next-generation reagents in metal extraction using froth and foam flotation. While the development of biosurfactants as flotation bioreagents is still in its infancy, it has witnessed important progress in the past five years. Recent studies have not only demonstrated the ability of biosurfactants to compete with conventional collectors but have also provided valuable insights into the experimental parameters affecting these two separation processes. Despite this progress, the interactions of biosurfactants with mineral particles, metal ions, and air bubbles under flotation conditions remain far from being fully understood. There is growing evidence suggesting that these interactions are more complex than observed for conventional petroleum-based collectors. We summarize the recent progress and outline the main remaining knowledge gaps, aiming to generate more interest in the intriguingly complex multifunctional properties of biosurfactants as collectors.
期刊介绍:
Current Opinion in Colloid and Interface Science (COCIS) is an international journal that focuses on the molecular and nanoscopic aspects of colloidal systems and interfaces in various scientific and technological fields. These include materials science, biologically-relevant systems, energy and environmental technologies, and industrial applications.
Unlike primary journals, COCIS primarily serves as a guide for researchers, helping them navigate through the vast landscape of recently published literature. It critically analyzes the state of the art, identifies bottlenecks and unsolved issues, and proposes future developments.
Moreover, COCIS emphasizes certain areas and papers that are considered particularly interesting and significant by the Editors and Section Editors. Its goal is to provide valuable insights and updates to the research community in these specialized areas.
