针对黄金矿山低品位资源的合理利用问题，从经济分析的角度，基于盈亏平衡理论构建了低品位资源价值评估的经济模型，并以某黄金矿山的低品位资源利用为案例背景，对模型进行了验证和实际应用。在综合考虑黄金价格、矿山利润和产量指标要求的情况下，基于所构建的模型优化得出了该矿经济合理的品位指标，并针对特定的经营目标条件进行了敏感性分析。研究结果为矿山低品位资源的科学利用和生产经营的正确决策提供了参考。
Aiming at reasonable utilization of low grade resources for gold mines , an evaluation economic model was built up based on the theory of profit and loss balance in the view of economic analysis .The model was verified and put into practice during a case study of low grade resources development in one gold mine .With the help of the model,such economic ore grade indexes were optimized considering the gold price ,profits,production requirements, and so on .Furthermore ,the model was also used for sensitivity analysis according to specific production targets .The re-sults can provide references for not only the scientific development of low grade resources ,but also for the rational de-cisions of production management for mining enterprises .
