Dalln mine, Scheuerfeld

A place of discovery of rare minerals

The Dalln mine was first mentioned as an active trade union in 1792. Around 1820 cobalt and copper ore were mined for a short time, further minor mining took place in 1829, 1845 and 1858. A larger copper ore vein was discovered through newly excavated shafts in 1861 and mining began after a 100-part union was reorganized with four miners. In 1907 the Dallner pit was made accessible again and put into operation in 1913. For the other Scheuerfeld pits, only applications for approval of a permit to dismantle were made. One ton of copper ore and five tons of brown iron stone were mined in the Dallner mine, shortly afterwards the mine was closed in 1915. The prospecting success was probably low. The beginning of the First World War with acts of war against Belgium in the autumn of 1914 probably ended this mining project, which had barely begun.

Rare minerals from the Dalln mine

The following minerals were found in the dump area of the Dalln mine near Scheuerfeld:

Alloklas, allophane, arseniosiderite, bismuthite, bornite, brochantite, chalcoalumite, chalcopyrite, chalcosine, chlorite, cuprite, cornubite, cornwallite, delafossite, goethite, hematite, cryptomelan, copper, malachite, oliveite, parnauite, pyritomalachite, pyritomalachite Tetrahedrite.

When determining the minerals found, EDX, Raman spectrum and an SXRD analysis method for arseniosiderite were carried out. My special thanks go to Mr. Günter Frenz, Cologne and Joy Desor from Bad Homburg.
