有关磁铁矿选矿各作业的基准单位投资费用和生产费用的数据列于表1。各种费用均据两项指标计算:按1吨给矿(进入作业的物料)和按1台主要工艺设备(标明设备类型、磨矿作业的原粒度和最终给矿粒度、单位生产能力)计算。此处提出的单位投资费用和生产费用的基准指标可用于预先计算磁铁矿选矿的类似
The data on the investment costs and production costs of the benchmark units for each magnetite beneficiation operation are shown in Table 1. All costs are calculated on the basis of two indicators: Calculated on the basis of 1 tonne of ore (material entering the work) and 1 major process equipment (indicating the type of equipment, the original size of the grinding operation and the final grain size, unit capacity) . The benchmark for unit investment costs and production costs presented here can be used for pre-calculation of magnetite beneficiation
