硫化矿浆的优先浮选过程在颇大程度上取决于硫化矿浆的氧化还原状态。与此相联系的是,硫化精矿分选的基本方法是以运用氧化还原过程中所产生的不稳定或稳定的变性物质为基础。当然,这一过程在电化偶的新鲜接触处(在磨矿时)最发达。在磨矿机衬板和研磨体磨损时所形成的细粒金属铁及其化合物,在这些过程中不是起决定性的作用。 The preferential flotation of sulphidized pulp depends largely on the redox state of the sulphidized pulp. In connection with this, the basic method for the classification of sulphide concentrates is based on the use of unstable or stable denatured substances produced during the redox process. Of course, this process is most developed at the freshly exposed galvanic couple (when grinding). The fine-grained metallic iron and its compounds formed during the wear of the mill liner and grinding body are not critical in these processes.
