    Definition method of recovering zinc and other relatively low boiling point metals from metallurgical waste (typically EAF flue dust) and other recycled materials using a rotary kiln (waelz kiln1)1waelz kiln [ IATE:3567259 ] Reference Wikipedia. Waelz process, https://en.wikipedia.org/wiki/Waelz_process [30.11.2015]
    Comment The zinc enriched product is referred to as waelz oxide, and the reduced zinc by product as waelz slag.The concept of using a rotary kiln for the recovery of Zinc by volatization dates to at least 1888.[1] 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 materials in the kiln); the two German firms later collaborated and improved the process marketing under the name Waelz-Gemeinschaf.
