Application Progress of Coordination Chemical Model of Mineral Flotation,Solution Chemical Calculation and Extended DLVO Theory in the Study of Flotation Mechanism
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.
