Leoben lime works

The lime works Leoben is a lime works and a gravel pit in Leoben in Styria. As Steirische Montanwerke AG , it was an important mining company and is now part of Wietersdorfer ( Baumit ).

location

The dismantling is visible from afar on the Galgenberg in the Leitendorf district in Leoben. Because of its shape due to the terraced mining, it is also known as the "second ore mountain ". The processing plants extend below this.

history

The plant was founded in 1874 by Franz II. Mayr-Melnhof , who had previously sold the entire Mayr'schen Eisenwerke in Donawitz . After taking over the Peggau lime works, the Steirische Montanwerke of Franz Mayr-Melnhof  KG emerged. Then there was also the Portland cement works in Peggau, the lime works in Bad Ischl and the line dismantling in Feldbach-Gossendorf , and at times the Steirische Kohlenbergwerke  AG (Kapfenberg, Weiz, Ilz, Gratkorn) was leased . In 1949, following the takeover of Österreichische Trass-Werke Ges.mbH, a new type of binding agent for building materials, Trassit , was developed .

In 1968 the Steirische Montanwerke  AG was taken over by the Tyrolean company Perlmooser , which became one of the largest building materials companies in Austria. In 1993/94, the Carinthian-Styrian Wietersdorfer Group , of which one branch merged in 1988 to form the Wietersdorfer and Peggauer cement works , bought the Steirische Montanwerke. After the takeover, major investments were made and the conversion from raw material extraction to finished products.

After that, the plant operated as Wietersdorfer und Peggauer Zementwerke GmbH , currently there are three sub-companies with headquarters in Klagenfurt, Carinthia. The companies also represent the brands baumit and Kema on site . The Steirische Montanwerke only exist in terms of formal law.

Geology and production

A finely crystalline, partly calcareous , partly dolomitic marble ( metamorphic limestone or dolomite stone ) is mined. It is a higher metamorphic ( crystalline ) formation within the Greywacke Zone , which, split into two lines, accompanied by green stone ( chlorite slate and hornblende stones ) and severely disturbed, runs from the Galgenberg westward over the lowlands and Jassing and behind the Liesingtal on the Fressenberg loses at Zmöllach . The rocks are embedded in a train of sandstone and phyllite from the Veitscher Nappe , which accompanies the fault as far east as Bruck and is marked by the course of the Mur . The whole crystalline formation (marble rocks and green) is south to the north-western directly lying mountain of St. Peter-free stone Traidersberg episode mentioned. Like the Kaintaleck Scholle, it represents the sedimentary base of the Noric Nappe of the Grauwackenzone, which was pushed over the Veitscher Nappe in the course of the formation of the Alps . In places (especially in the Leoben - Galgenberg area) the Traidersberg series has been inserted several times into the Veitsch ceiling below.

This occurrence is not related to the weakly metamorphic Devonian carbonate rocks to the northwest, at St. Peter-Freienstein ( Kalkwerk am Kulm ) and the Reiting massif, these represent the sedimentary overlay of the Traidersberg series Galgenberg neighboring limestones of the Veitscher ceiling (weakly metamorphic Triebenstein limestone from the carbon ), which z. B. build the south face of the Häuselberg (south of the Leoben lime works) and the rock ridge under the Pampichler-Warte (south-east of Leoben) and be mined in the Lebergraben quarry.

The mining area on the Galgenberg covers around 7  hectares (1990: 6.7 hectares). Today it is used to produce high-quality ready-made plasters , fertilizer lime and gravel .
