一、简况长江中下游富铜、富铁成矿带;华北地台燕山期中酸性侵入体与奥陶纪灰岩正规接触带对我省占有重要位置的铁—铜—硫矽卡岩型、热液充填交代复合型铁矿床的空间分布、矿床中伴生 Cu、S、Co、Au、Ag、Pb、Zn、Mo、V、B、Ga、Ti、Ni……等元素的富集起着严格的控制作用。这些中量或微量元素的富集,大大提高了矿床的经济价值,为我省黑色冶金矿山伴生资源的综合利用,提高矿山综合经济效益,延长矿山寿命奠定了基础。特别近年来,由于加强了矿山地质勘探和生产勘探工作,对矿床中的伴生有益元素进行了综合勘探、综合评价,狠抓了采、选配套。加强了采矿 I. Brief Introduction The copper-rich and iron-rich metallogenic belts in the middle and lower reaches of the Yangtze River; the normal contact zone between the intermediate-acidic intrusions and the Ordovician limestone in the Yanshanian stage of the North China Platform played an important role in iron-copper-sulfur skarn-type, In addition, the enrichment of elements such as Cu, S, Co, Au, Ag, Pb, Zn, Mo, V, B, Ga, Ti, The role of control. The enrichment of these medium or trace elements has greatly enhanced the economic value of the deposit and laid the foundation for the comprehensive utilization of the associated resources of black metallurgical mines in our province, improving the comprehensive economic benefits of the mines and prolonging the life of the mines. In particular, in recent years, due to the strengthening of geological prospecting and production exploration in the mine, the associated beneficial elements in the deposit have been comprehensively explored and comprehensively evaluated, and the selection and matching of production have been emphasized. Mining has been strengthened
