提高有用矿物的品位和降低矿石中有害组分的含量是选矿设计及其过程控制的首要任务。选别作业则是整个选矿工程的核心。无论是选前矿石准备作业还是选后处理作业都必须满足选别作业的要求。我们认为,选别效率的提高,意味着提高主要设备的处理能力,改善分选界限(包括扩大处理的粒度范围,特别是处理较细的粒级),进一步改善现有作业方式 Increasing the grade of useful minerals and reducing the amount of harmful components in the ore are the primary tasks of beneficiation design and process control. Sorting operation is the core of the beneficiation project. Either pre-ore preparation or post-processing operations must meet the requirements of sorting operations. In our opinion, the improvement of sorting efficiency means that the processing capacity of major equipment will be improved, the sorting boundaries will be improved (including the extension of the granularity of processing, especially the handling of finer grading) and the further improvement of existing operating modes
