西藏雄村铜金矿床经济评价

Economic Evaluation of Xiongcun Copper-gold Deposit in Tibet

西藏雄村铜金矿是最近在西藏日喀则地区发现的一个超大型矿床在对矿床地质特征、经济技术条件进行分析的基础上,采用静态和动态评价方法对矿床经济价值进行评价,通过投资利润率、投资收益率、投资回收期等经济技术指标开展盈亏分析,选取处理成本、铜价作为不确定因素进行了单变量敏感性分析,同时在保证边界品位的基础上以处理成本和回收率作为不确定因素进行了双变量敏感性分析,认为该矿床具有较高的经济价值,矿山生产建设的条件在经济上是可行的。

Xiongcun copper-gold deposit is a super-large deposit recently discovered in Shigatse District,Tibet.On the basis of analyzing the geological characteristics and the economic and technical conditions and evaluating the economic value of the deposit with static and dynamic evaluation method,this paper analyzes the gain and loss in terms of profit ratio of investment, rate of return on investment and investment payoff period.Then a univariate sensitivity analysis is done selecting such factors as the treatment cost and copper price and a bivariate sensitivity analysis is done with the treatment cost and the rate of recovery.The results indicate that Xiongcun copper-gold deposit has a relatively high economic value and that the conditions of productive construction of the deposit are economically feasible.
