Detailed Economic Evaluation For Gaerqiong Copper Deposit In Geji County Tibet Autonomous Region

Detailed technical and economic evaluation for ore deposit is based on geologicalappraisal according to the technical and economic conditions, a kind of economy profitestimation for a certain indicated ore deposit which is going to be mined for industrydevelopment. This kind of technical and economic evaluation for ore deposits is ofsignificance to geological survey and mine designing as well as development. Thispaper aims to find out an optimized schedule for GaErQiong copper mine throughdetailed technical and economic evaluation for deposit. Based on the geological surveyin the field,then analyzed GaErQiong geological features in detail and identifiedcopper grade and reserves, and other important industry indicator, from the currentcopper market situation, through an analysis of the external construction of miningconditions and existing mines realistic mining and technical conditions, combined withthe existing design of recoverable reserves, Cash Flow and Inner Return Rate areadopted in this paper to calculate important indexes such as investment interest rate.investment return period, net present value and inner return rate,etc.The purpose is toselect one schedule in which the technical conditions and economic profit can reach theoptimized point.This paper analyzes the domestic and international development of the technicaland economic evaluation for deposit.Diseount on cash flow method ofPrinciple， t hebasic content and parameter selection， use，note the use of severalareas of analysis， integrated with the international diseount cash flow method and theprinciple conditions of use，as well as International and domestic discount cash flowmethod of analysis and comparison， pointing out that the distinetion between thetwolies.Through the discount cashflow method，combining GaErQiong copperrmineproduetion， set bench marks for assessment，To effeetively assess reasonable parameters of copper mining GaErQiong,use Cash Flow Inner Return Rate andPayback period detailed technical and economic evaluation for the deposit.Considering the risk-resist ability of these schedules which theymayencounter,sensitive analysis is carried out to estimate those indexes and it isindicated that every index is within the controllable limits. Finally, this paper indicatesthat GaErQiong will be very profitable in employing the schedule due to its convenientlocation and transportation conditions plus the favorable metallogenic setting;meanwhile, it is also recommonded that recycling the accompanying elements insidethe deposit and building a smelting plant would be better for GaErQiong Copperdeposit.Finally, give some suggestions to the production and development of mine.hope tostrengthen the technical conditions of production quickly and mine management,improve environmental and ecological benefit, learn from experiences of other mining,construction eco-type mines to achieve long-term goal of sustainable development forfuture generations benefit.
