摘要
当把实验室的理论研究成果应用于生产实践时,经常发现两者间存在明显的差异,使得浮选研究,尤其是纯矿物研究的实用性大大降低,造成理论研究与实际应用结果存在差异的原因在于浮选过程的复杂性,研究中不仅要关注药剂在矿物表面吸附的化学原理,还需要对浮选所处的化学环境(溶液条件、伴生矿物)进行综合的考虑分析.近年来,随着矿物浮选配位化学模型的提出和溶液化学理论的不断完善,给实现理论研究指导实际生产的目标提供了可能性.因此,收集总结了国内外关于矿物浮选配位化学模型、溶液化学计算和扩展的DLVO理论在矿物浮选机理研究中的应用实例,从理论内容、计算过程和应用实例等方面进行介绍并加以评论,以期对将来的浮选研究起到一定的参考作用.
Abstract
When the theoretical research results of the laboratory are applied to the production practice,it is often found that there are obvious differences between them,which greatly decrease the practicability of flotation research,especially pure mineral research.The reason for the difference between the theoretical research and practical application results lies in the complexity of the flotation process,it is not only necessary to pay attention to the chemical principle of the chemicals adsorption on the mineral surface,but also to comprehensively consider and analyze the chemical environment of flotation(solution conditions and associated minerals).In recent years,the proposed coordination chemical model of mineral flotation,together with the continuous development of solution chemistry theory,provides the possibility to realize the goal of theoretical research guiding practical production.In this paper,the application examples of coordination chemical model of mineral flotation,solution chemical calculation and extended DLVO theory in the study of mineral flotation mechanism at home and abroad are collected and summarized.Introduction and comments are given regarding the theoretical content,calculation process and application examples of the three theories,so as to provide a reference for the future flotation research.
