Waelz Process
The Waelz process is one of the most efficient technologies, in terms of capacity and quality, able to recover nearly 90% of zinc content from such powders. The Waelz process is a 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 kiln).
