近年来,有用矿物选矿方面有了明显进展:逐步以新型设备装备了企业,应用了新方法和联合工艺流程,以及自动化的管理体系。这主要取决于下列诸原因: 1 入选原料性质有了很大改变由于富的、易选的以及组成简单的矿产资源日益枯竭,为了选别难选的、含泥质的、氧化的以及细粒嵌布矿石,需要较复杂的工艺;并且目前也要 In recent years, significant progress has been made in the beneficiation of useful minerals: equipment is gradually being equipped with new equipment, new methods and process flows are being applied, and automated management systems. This depends mainly on the following reasons: 1 Significant changes in the nature of the incoming raw materials As the rich, readily available and simple depleted mineral resources are depleted, in order to sort out hard-to-choose, muddy, oxidized and fine Cloth ores require more complex processes; and at the moment
