Former mining sites in Germany

The first concessions to mine zinc and lead in Germany were acquired in the mid-1800s. Exploitation at most of the concessions ceased in the late 19th to early 20th century, with a handful of mines continuing activities into the middle of that century. The last active mine was closed in 1978. 

Several mining concessions located near the cities of Cologne and Koblenz remain in Umicore’s possession. Extensive risk assessment has been carried out with the assistance of specialized consultants. After consultation with the mining authorities, work has been undertaken to further reduce any risks posed by these sites (e.g. from subsidence). Monitoring of the sites is performed on a continuous basis to ensure the safety of the sites.
