Detailed Economic Evaluation For Tang Tang Copper Deposit In Hui Dong Coincil Si Chuan

Detailed technical and economic evaluation for ore deposit is based on geological appraisal according to the technical and economic conditions,a kind of economy profit estimation for a certain indicated ore deposit which is going to be mined for industry development.This kind of technical and economic evaluation for ore deposits is of significance to geological survey and mine designing as well as development.This paper aims to find out an optimized schedule for Tangtang copper mine through detailed technical and economic evaluation for deposit.Based on the geological survey in the field ,then analyzed Tangtang geological features in detail and identified copper grade and reserves, and other important industry indicator, from the current copper market situation, through an analysis of the external construction of mining conditions and existing mines realistic mining and technical conditions, combined with the existing design of recoverable reserves, Cash Flow and Inner Return Rate are adopted 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 to select one schedule in which the technical conditions and economic profit can reach the optimized point.This paper analyzes the domestic and international development of the technical and economic evaluation for deposit.Diseounton cash flow method of Principle,the basic content and parameter selection,use,note the use of several areas of analysis,integrated with the international diseount cash flow method and the principle conditions of use,as well as International and domestic discount cash flow method of analysis and comparison,pointing out that the distinetion between the twolies.Through the discount cashflow method,combining Tangtang copper rmine produetion,set bench marks for assessment,To effeetively assess reasonable parameters of copper miningTangtang,use Cash Flow Inner Return Rate and Payback period detailed technical and economic evaluation for the depositConsidering the risk-resist ability of these schedules which they may encounter,sensitive analysis is carried out to estimate those indexes and it is indicated that every index is within the controllable limits.Finally,this paper indicates that Tangtang will be very profitable in employing the schedule due to its convenient location and transportation conditions plus the favorable metallogenic setting;meanwhile, it is also recommonded that recycling the accompanying elements inside the deposit and building a smelting plant would be better for Tangtang. copper depositFinally, give some suggestions to the production and development of mine.hope to strengthen 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 for future generations benefit.
