摘要
随着药剂性质研究理论和方法的不断进步,浮选药剂构效关系也从定性分析逐步转变至定量研究阶段。定量研究的关键是确定一些可预先判断药剂分选性能的原理或准则,即浮选药剂性能判据。介绍了目前常见的浮选药剂性能判据及其优缺点,以期为高效浮选药剂的研发提供依据。性能判据按大类可分为药剂性质判据、基团或键合原子性质判据以及结合能判据等。这些判据多关注药剂与矿物表面的作用过程,导致其在使用过程中多起到筛选作用。为开发新型高效的浮选药剂,需要依托浮选药剂与矿物作用强弱的表征理论和方法,有针对性地选取浮选药剂性质参数,建立性质参数与作用强弱的相关关系,从而形成新的、更高效的药剂性能判据。
With the development of the theory and method of chemical properties research,the relationship between the structure and properties of flotation reagents has gradually changed from qualitative analysis to quantitative research.The key of quantitative research is to determine some principles or criteria that can judge the separation performance of reagents in advance,that is,the performance criteria of flotation reagents.This paper briefly introduces the common design criteria of flotation agents and their advantages and disadvantages,in order to provide a basis for the research and development of high−efficiency flotation agents.The design criteria can be divided into chemical property criterion,group or bonded atom property criterion and binding energy criterion.These criteria pay more attention to the interaction process between the reagent and the mineral surface,which leads to its screening function in the process of use.In order to develop novel and efficient flotation agents,it is necessary to rely on the characterization theory and method of the strength of the flotation reagents and minerals,select the property parameters of flotation reagents and establish the correlation between the property parameters and the strength of the action,so as to form a novel and more efficient performance criterion of flotation reagents.
