Slag bath

As slag or iron bath is known, inter alia, spa baths , which are fed by arising during the metal smelting process water.

In order to convert the slag / blast furnace slag produced during the smelting of copper or iron into granulate that can be used as a building material , it is quenched with water. The water absorbs sulfur and other minerals from the slag and thus has a healing effect similar to that of the well-known therapeutic baths . Because the water is often used multiple times in the granulation process, the minerals are even more concentrated than with natural springs.

Examples of slag baths are

• the former Bochum sulfur bath in the hamlet of Hamme , which was fed from the slag of the Bochumer Verein (coordinates 51 ° 29 ′  N , 7 ° 11 ′  E ),
• the pools in the former Schallacker outdoor pool in Hörde , which were fed with sulfur from the granulation system of the Hörder Bergwerks- und Hütten-Verein (coordinates 51 ° 29 ′  N , 7 ° 30 ′  E ),
• as well as the slag bath of the copper smelter in Hettstedt / Saxony-Anhalt and others.

From the original meaning z. B. as the city of Eisenbad, near Kitzbühel in Tyrol , Austria .
