Waelz process - Wikipedia

The concept of using a rotary kiln for the recovery of Zinc by volatization dates to at least 1888. A process was patented by Edward Dedolph in 1910. Subsequently, the Dedpolph patent was taken up and developed by Metallgesellschaft(Frankfurt) with Chemische Fabrik Griesheim-Elektron but without leading to a production scale ready process. In 1923 the Krupp Grusonwerk independently developed a process (1923), named the Waelz process (from the German Waelzen, a reference to the motion of the material
