Abstract. First results are presented about the abundance and distribution of rare earth elements (REE) in the Úrkút manganese ore deposit. Geochemical analyses of samples of the manganese carbonate sequence reveal that the average REE content decreases from the base to the top. A positive Ce anomaly and the enrichment of REE in …

Underground mining is often used when the manganese ores are too deep to mine profitably by open-pit methods. In return, this is the most important manganese ore, as it is a high enough grade to cover the more expensive underground mining costs. Britannica explains that natural manganese is processed by hydrometallurgical and …

During exploitation of the Úrkút Mn-oxide ore, a snow-white highly siliceous (97 to ∼100 wt.% SiO 2) rock was discovered in the early 1950s between the dip-slope shaft and shaft No. III (Fig. 1, Fig. 2).This siliceous rock was called by various names during the course of exploitation of the Mn ore including hydroquartzite, ceramic sand, chert silt, and …

Ezért az Úrkúton is ismert szénelőfordulásra újabb bányát terveztek a szeszgyár és a gőzgépek szénszükségletének biztosítására. A bányát 1917. március 1-én nyitották meg. Mindössze napi 1–3 vagon szenet termeltek, de közben felfigyeltek a mangánércre – a szén mellett hamarosan már abból is hoztak a felszínre.

Abstract. A stratiform Mn-deposit of Liassic age was formed in the Tethys geosyncline at Úrkút, Hungary, with rhodochrosite as the predominant mineral (∼ 50%). Among clay minerals goethite is found in the lower part and pyrite in the upper part of the ore-bearing layer. The close association of Fe and Mn is due to the fact that the ore was ...

Previously, little attention has been paid to terrestrial radioisotopes (U, Th, 40K) occurring in manganese ores, despite the fact that the biogeochemical relationship between Mn and U is versatile. Occurrence of terrestrial radioisotopes in great amounts during mining on a long-term causes significant radiation exposure. It is important to inspect black shale-hosted …
