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 …

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 ...

The Manganese Mining Process. More than 25 million tons of manganese are mined every year. Most manganese mining occurs in open pits. Although there are processes in place to mine manganese nodules in the ocean floor, they cannot complete with land-based mining production. Once the ore is mined, it's transferred to a …
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 …
