Résumé : With its subsidiary companies and industrial participations in Belgium and abroad, Vieille-Montagne constitutes an important mining and metallurgic group devoted to zinc and lead and to the processing and valorisation of the elements associated with these two metals in ores. The society originates from the very old zinc mine situated at La Calamine. This deposit, already exploited in the Middle Ages, provided during several centuries the calamine necessary for the craft brass industry in the Mosan region and the Aachen area. At the beginning of the XIXth century, the mining company became a metallurgic enterprise. During the XIXth century, Vieille-Montagne became the leader of the European zinc industry and the main pioneer for the marketing and promotion of this metal and its laminated products throughout the world. Its activities rapidly spread to France, Germany, Sweden and other countries of Europe and northern Africa. The present role relates the history of the zinc industry in the ancient Duchy of Limburg, from its origins to the present day. -from English summary
