摘　　要：邯邢铁矿是中国重要的铁矿山之一,利用钻探方法对西石门铁矿后井尾矿56种元素进行地球化学评价,了解元素在尾矿库中的空间分布特征。研究表明,尾矿库中Fe、Cu、S、Co元素可进一步开采利用,局部可达到或超出原生矿的工业品位要求。后井尾矿中Fe、S、Cu、Co资源量分别是28.5×104t、4.5×104t、0.36×104t和0.2×104t,适合二次综合开发利用,同时研究中也探索了这些元素在尾矿沙中富集作用和富集机理及影响因素,旨在探索出一种利用地球化学评价尾矿的资源量勘查方法,加速实现中国尾矿资源化。The resource crisis has attracted much attention all over the world with the development of the economy.The exploration of new mines should be accompanied by improving comprehensive utilization of the tailings.Therefore,exploring new mines together with improving comprehensive utilization of the tailing resources seem to be the way to solve this problem.The Hanxing iron mine is one of the main iron mines.However,the resource shortage and environmental problem have restricted its development with the increasing requirement and exploitation of iron ores.In order to prolong the service life of he mine and study the characteristics of iron ore tailings,the authors carried out investigations and discovered that there exists obvious enrichment of such elements as Fe,Cu,S and Co in the iron ore tailings,which can reach or even exceed the resource reserves of economic primary ores.Reasonable and adequate utilization of tailing resources has great practical significance for the resource recovery of iron ore tailings.
