摘要

通过对马坑铁矿铁矿石开展"高压辊磨-预先磁选抛尾"工艺的半工业试验研究,确定在已有的选矿生产设备和设施的基础上,增加"高压辊磨-预先磁选抛尾"工艺,将选矿厂的处理能力由300万吨/年提高到500万吨/年。
        This paper conducts a semi-industrial trial on the "high pressure roller mill-pre-magnetic separation of tailings" beneficiation process of Makeng Iron Mine. According to the results of the study, we decided to increase the "high pressure roller mill-pre-magnetic separation of tailings" process on the basis of existing ore dressing production equipment and facilities. This measure will increase the processing capacity of the concentrator from 3 million tons per year to 5 million tons per year.
