Copper Processing

---

Opposite the site on the opposite slope, where the tennis court is today, once stood the heart of Mühlbach's copper ore processing. Due to the constantly increasing demands on the processing plants at Mitterberg, a new processing plant was built in Mühlbach in 1909. A wooden frame structure. built on concrete pedestals, measuring 60 meters in length and 26.5 meters in width, with multiple floors, was an impressive construction at that time. Here, the ore coming from the mountain was separated from the barren rock, and the pure copper ore was further transported to Mitterberghütten.

On the night of December 7 to 8, 1920 due to a mistake by an employee, a catastrophe occurred, and the entire processing plant was engulfed in flames The building was rebuilt in the following two years in fireproof reinforced concrete with fire compartments at full size. Until its closure in 1977, the ore from the mine was processed into copper concentrate in this building. This was delivered to Brixlegg in Tyrol for copper production. In 1978, after the closure, this building also fell victim to a fire and was subsequently dismantled.
