Theux, Belgium/theux140
Previous | Home | NextThe mine "Le Rocheux" near Oneux held the best thallium-rich ores of all, although Lamy analyzed and found thallium in many mines in the southern part of Belgium. Le Rocheux mine dates from the 14th century, when it mined for its iron ore. The peasants worked their farms in the summer and the mines in the winter. There were a number of iron forges which processed the iron ore. This modern map shows Le Rocheux is now a nature preserve, with the original mines covered and the landscape reworked.
