摘要
为利用德兴铜矿矿床中２０％的表外矿，分析了表外矿的分布特点，进行了生产配矿控制、堆浸及根据多元素综合价值品位重新圈定开采境界等多途径的表外矿利用，取得了显著的经济效益和社会效益。
In order to utilize ore below cut off grade of 20% Cu in copper deposits of Dexing Copper Mine,and based on the analysis for distribution charactaristic of ore below cut off grade of 20% Cu,the different way of utilizing below cut off grade,such as,blending control of various grade ore,using pile leaching method and redelimiting mining limit based on comprehensive value of multi element,are used,thus,the obvious economic and social profits are obtained.
