The Mausbach mine in Heidelberg in the Ziegelhausen district was a manganese ore mine . It existed from 1890 to 1919.
history
The expectation from Röchling'schen Eisen- und Stahlwerke (today: Buderus Edelstahl ) was granted on December 4, 1890 by Friedrich I, Grand Duke of Baden . A 2-year exploration phase began with the excavation of several test shafts up to 20 m deep in the district northwest of Ziegelhausen, during which a manganese ore deposit with a thickness of 60 cm was discovered. The manganese deposits were in oxidized form as Manganmulme in the geological layers of the Zechstein and Rotliegend of Perm and were as mineable found.
At a depth of 20 m , a 70 m long test section with wooden door frames was first driven .
From 1893 a main conveyor tunnel with a width of 2.80 m and a height of 2 m was driven 400 m north . The first 35 m led through sandstone debris and were therefore lined up . The rest of the route led through Zechsteindolomit and was therefore stable. In November 1895 the tunnel was expanded to 362 m, in spring 1896 the manganese ore deposit was reached. By the end of 1896, the tunnel was extended to 460 m and 130 t of manganese ore were mined. The low manganese content and poor ore quality raised doubts about profitability. In 1897 another test shaft with a depth of 70 m was set up, which did not reveal any deposits that were worth mining. Because of this, the mine was temporarily closed in July 1897.
From 1918 the operation was continued for a few months, another 97 tons of manganese ore were mined. The low manganese content of the ore and the laborious ore transport to the Völklinger ironworks did not justify any further mining.
It was not until 1936 that funding was started again, but it was quickly stopped.
