Regional Hydrogeology

The Kcd (Karst colluvium and deluvium) deposit of Dongxiang copper mine had long been considered as a kind of ancient diluvium, alluvium and proluvium in Cretaceous Karst depression. Based on lithology and morphology analysis of Kcd, and further research for regional hydrogeology and hydrogeochemistry, it was considered as a new special Karst deposition form of metal ore in this project. In the oxidation zone of sulfide mineral deposit, Kcd was a deposition mixture of dolomite powder (sand) and eluvium of dolomite wall rock, which were generated by the action of sulfuric acid water on wall rock, and the collapse deposition from the overlying K2n red beds. This kind of deposition was still generating and developing today. The monoclinal structure, primary sulfide mineral deposit occurred in clastic rock and claystone, dolomite and siliceous dolomite with 160m deep in underground water system, all that provided the development conditions of metal ore Karst deposition. This viewpoint could not only guide the copper ore exploration of Dongxiang type, but also provide a good case for Karst development in sulfide mineral areas.

Floatation Process

Process mineralogy research of a mixed copper ore is studied to identify the occurrence mode of copper and to analyze the mineralogical factors influencing the floatation results. The results show that the ore has features of "high-sulfur, high copper", "various copper mineral types", "fine copper mineral granularity" "disorderly copper mineral distribution", which belongs to the more difficult processing high sulfur mixed copper ore. Therefore, in order to effectively utilize the copper mine resource, floatation process or combination of floatation-hydrometallurgy process should be adopt.

Copper Ores

Jovanovič has recently drawn attention to the early copper mine at Rudna Glava in the copper mining area of Maidanpek-Bor in Eastern Serbia (Jovanovič 1979, 103). This copper deposit has iron associated with it. In some respects this occurrence of iron and copper together compares with the deposit at Phalabora in South Africa where copper and other minerals are mined today. Rudna Glava has been a copper mine in the Chalcolithic period and an iron mine in the Turkish period. Today it is worked out, but the working of the iron ore has left exposed some of the shafts and galleries used by Chalcolithic and Bronze Age copper miners. It has been possible to obtain a sample of the copper ores used in the early periods and integrate them into a smelting programme (Tylecote et al. 1977, 305), the main purpose of which has been to determine the partitioning of the three elements between the ore, the slag and the metal. The object of this exercise was to try and relate the artefacts, the slag, and metal to the ore source. So far, ores from the British Isles, Spain, and Africa have been examined and reported (Tylecote 1977). The sample from Yugoslavia came rather too late for the first report but the work is continuing.The smelting work described in this report was carried out by Ali Ghaznavi and the analyses were kindly made by R. Hetherington formerly of Newcastle University and Dr P. T. Craddock of the British Museum Research Laboratory. I have to thank Dr B. Jovanovič of the Archaeological Institute, Belgrade, for supplying the material and inspiring the work.
