Collector Innovation for Efficient Recovery of Fine−grained Molybdenite: from Experimental Screening to Computational Modeling
-
摘要:
微细粒辉钼矿（MoS2）的高效浮选回收是钼资源可持续开发的关键挑战。聚焦捕收剂创新，系统综述了从实验筛选到计算模拟的研究进展：实验层面，纳米乳液、复合捕收剂通过尺寸效应、协同吸附等机制显著提升微细粒辉钼矿回收率；计算模拟层面，密度泛函理论（DFT）与分子动力学（MD）揭示了捕收剂−矿物界面作用机制，支撑了从“经验试错”向“理性设计”的范式转变；新型捕收剂体系也在工业中进行应用实现了回收率的大幅提升。未来研究需突破多尺度模拟精度、绿色药剂成本控制等瓶颈，推动钼资源加工向高效低碳方向演进。
Abstract:Efficient flotation recovery of fine−grained molybdenite (MoS2) represents a critical challenge for the sustainable exploitation of molybdenum resources. This review focuses on collector innovation, systematically summarizing recent advances from experimental screening to computational modeling. At the experimental level, nanoemulsions and composite collectors have significantly enhanced the recovery of fine particles by size effects and synergistic adsorption mechanisms. At the computational modeling level, density functional theory (DFT) and molecular dynamics (MD) simulations have elucidated the interfacial interaction mechanisms between collectors and mineral surfaces, facilitating a paradigm shift from "empirical trial−and−error" to "rational design." Emerging collector systems have demonstrated substantial improvements in recovery during industrial tests. Future research must address bottlenecks such as multiscale simulation accuracy and cost−effective green reagent development to advance molybdenum resource processing toward high−efficiency and low−carbon practices.
