Comprehensive Marginal Grade Of Applied Research, In Dexing Copper Mine

There's abundant copper resource with low copper grade and high gold grade in Dexing Copper Mine. That would be regarded as waste ore and be abandoned according to the traditional single copper requirements so the gold in it would be waste. In the past, affected by the planned economy, the optimization of industrial requirements of Dexing Copper Mine got such a slowly progress that waste a lot of mineral resources and the other resource. For improve the utility of the scarce mineral resource, Dexing Copper Mine conducted a study on the difficult problem of Ore body evaluation in the field of Mineral resources comprehensive utilization. With importing of the software of minning industry named MINESIGHT, importing the cut-off grade to manage the geological resource and improve the mining index, moreover to achieve the dynamic management of geological resource. By means of analysis the geological data and the geology survey, reveal the law of the ore body's distribute of low grade copper and high grade gold. Conclude the concentrating character of low grade ore by experiment. For solve the difficulty of dealing with the data of cut-off grade, the computer software system has been developed. On basis of above, Dexing Copper Mine create the theory system of integrated cut-off grade for the first time in China; give the way of evaluation of integrated ore body and the research thinking; make the convert ratio of integrate grade; create the formula of the integrated cut-off grade; work out the best index of integrated cut-off grade of ore block by using all present value method, and with the using in the ore resource development, getting very well Social benefit and economic benefit.Integrated cut-off grade theory system is stable and reliable, which can solve the difficult of the utility of resource of high grade gold and low grade copper efficiency and give the study ideas of comprehensively utility of other associated element. It has nice Industrialization prospect and good market demand, and promotes national sustainable development, worth to spreadWith the development of science and technology and Mineral comprehensive recycling theory be well known and the national economic development, minning company should as soon as use the new theory, new technology to improve the mine production process, optimize deposit mining industrial index,for rational use of natural resources and protect enterprise sustainable development...
