A systematic review of research advances in the interfacial regulation of magnesite flotation: Insights and perspectives

In light of the gradual depletion of high-quality magnesite resources, it becomes paramount to employ flotation as a method for the efficient and cost-effective extraction of magnesium resource from magnesite. Despite an extensive body of research on the interfacial regulation of magnesite flotation, comprehension of various aspects and associated terminologies remains ambiguous. Persistent challenges in the interfacial regulation of magnesite flotation impede its development and industrialization, presenting a pressing obstacle. A comprehensive analysis of the current research status in magnesite flotation is undertaken, encompassing five key aspects: mineral characteristics of magnesite ore and its gangue, interfacial regulation of mineral interactions, interfacial regulation of inevitable metal ions, interfacial regulation of flotation reagents, and progress in flotation process research. Subsequently, proposed are novel directions and technological frameworks for the future of magnesite flotation interface regulation, incorporating mechanisms investigation, reagent design, biological flotation, process enhancement, and tailing utilization. These endeavors aim to update the existing system, offering insights and technological references for efficient desilication and decalcification in industrial production.
