The so-called “Reichswerke Hermann Göring” was an industrial conglomerate of Nazi Germany. Demand for iron ores and steel rose in line with the rise in military spending. So the domestic ore reserves in the city of Salzgitter were badly needed. Therefore, Göring announced that the Reichswerke would begin mining and processing Salzgitter ores and that the government would take over privately held ore deposits. A large mining factory was established in Salzgitter to extract and process iron ores, which often was a target of the Royal Air Force and United States Army Air Force. However, the conglomerate was dismembered by the Allies in 1945.
