新建或扩建型铜矿山低品位矿石采选经济可行性分析

摘要

本文在即将颁布的国家标准《铜矿山低品位矿石可采选效益计算方法》的研究基础上，对铜矿山在低品位矿石采选效益计算公式进行分析，主要的目是为新建或改扩建型铜矿山低品位矿石的采选经济可行性分析提供一套通用的计算方法和体系，为铜矿山低品位资源的利用提供技术依据，也为政府补贴数额和税费优惠幅度提供计算依据。%Based on the study of the issuing China national standard "Benefit calculation to determine the mining and processing of low -grade ore of copper mine", The paper analyse the computational formula of the mining and pro-cessing of low -grade ore of copper mine in order to offer a system of feasible computing method , offer a technical basis for using of resources , and offer a technical basis for government subsidies and tax preferential policy .
