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

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.
