矿产资源经济成本筛选法在西藏冈底斯成矿带铜多金属矿经济评价中的应用

Application of Economic Cost Fileters on copper polymetallic deposits in Gangdese metalligenic belt in Tibet

摘要: 为提高西藏冈底斯成矿带铜多金属矿勘查开发工作的经济效益，该文基于甲玛铜多金属矿地质、采矿和选矿技术参数，建立了适合冈底斯成矿带铜多金属矿经济评价的改进的经济成本筛选模型。并运用该模型对西藏冈底斯成矿带10个典型铜多金属矿床(点)进行经济评价，结果发现：2个铜多金属矿(点)具有经济价值，1个铜多金属矿床(点)具有边际价值，7个铜多金属矿床无经济价值。

Abstract: In order to economically explore and develop the copper polymetalligenic deposits in Gangdese metallegenic belt，the improved Economic Cost Filter for copper polymetalligenic deposits in Gangdese metallegenic belt is set up on the basis of the technique parameters of geology，mining，and beneficiation of Jiama copper polymetalligenic deposit.The 10 typical copper polymetalligenic deposits are valued by the improved Economic Cost Filter.The result shows that two of them are economic，one of them is marginal，and the rest seven are uneconomic.
