| 摘 要： | 基于盈亏平衡理论,建立了焦家金矿低品位资源的技术经济评价模型.根据待投入成本的不同,对处在不同工程控制之下的低品位资源进行了评价和分级;计算了级差品位,研究其是否具有回收价值.结合Surpac软件建立的三维矿床模型对焦家金矿的低品位矿化体进行了估算和评价.在黄金价格180元·g-1情况下,级差品位的应用可使矿山增加2.73 t金属量,并可产生7 500万元的新增利润.

| Abstract: | A technical and economic evaluation model for low-grade resources in Jiaojia Gold Mine was built up based on the breakeven theory. In different production stages, the corresponding follow-up cost was calculated, based on which the low grade resources were evaluated and classified. Differential grades were calculated to determine whether it is worthy to recovery them. The threedimensional deposit model in combination with Supac software was adopted to estimate and evaluate low-grade mineralized deposits in Jiaojia Gold Mine. Given the gold price of RMB ￥ 180 g-1, the application of differential grade can bring the mine additional 2.73 t gold metals, as well as RMB ￥ 7 500 million profits. |
