Stavrakeva, D., N. Tzankova. 2016. Chemico-mineralogical characterization of ancient slags from Rosen Ore Field. Part 1 – Propadnala voda deposit. – Univ. Min. Geol., 59, 1, Geol., 55-60 (in Bulgarian with English abstract).
ABSTRACT. The objects of this study are ancient slags from the vicinity of the Propadnala Voda deposit, Rosen orefield. With the methods of optical microscopy in transmitted and reflected light, X-ray powder diffraction, chemical analyses by ICP-OES, SEM, and X-ray microanalyses, found that the slags consist mainly of iron-siliceous and iron-oxide phases. The analyzed samples are with high iron content, the presence of copper, sulfur, sulfide aggregates, impurities of phosphorous, cerium, and lanthanum. Drops of copper are observed in all studied samples. These slags are a by-product of copper mining activity using copper sulfide ore was processed. They are evidence of ancient metal production in the area around the Propadnala Voda deposit.
