一、前言我矿是有三十多年历史的老矿,建国以来,随着矿石可选性的变化,原矿品位逐渐下降,原矿处理量逐渐增大,进行过多次选矿流程改进,在流程结构上有较大变化,选矿指标也有不同程度的提高,但有些改进效果较好,有些改进效果并不显著。下面就我矿几次较大的流程改进进行分析和讨论,以便在贯彻“调整、改革、整顿、提高”方针过程中,采用合理的石墨选矿流程,提高选矿的技术经济指标,为赶超世界先进水平而共同努力。二、几次流程改进及分析1.二次再磨六次精选的石墨浮选流程1957年以前,我矿石墨浮选流程比较简单。流程的
I. INTRODUCTION Since the establishment of the PRC, since the founding of the People’s Republic of China, mine has gradually reduced the grade of ore and the ore handling capacity has been gradually increased. Since the founding of the People’s Republic of China, many beneficiation processes have been improved. During the process There is a big change in the structure, beneficiation indicators also have different degrees of improvement, but some improvements are better, and some improvements are not significant. The following several major mine process improvement mine to analyze and discuss in order to implement the “adjustment, reform, rectification and improvement” process, the use of reasonable graphite beneficiation process to improve the technical and economic indicators of beneficiation, in order to catch up with the world Advanced level and work together. Second, a few times to improve and analyze the process 1. The second resurface six selected graphite flotation process Before 1957, I mine graphite flotation process is relatively simple. Process
