Geochemical characteristics of Hanxing style iron ore tailings, Hebei Province

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.
