•1 Million Tons of EAF dust produced in US each year
•EAF options today include landfill or Waeltz kilns
•Current options result in loss of valuable resources
•PIZO process developed to take advantage of all components of EAF dust in a more energy efficient manner
DESCRIPTION OF THE PIZO PROCESS
•Primary processing unit is a channel induction furnace
•Molten bath of iron serves as a heat sink to rapidly heat feed materials
•Feed material is a mixture of metal oxides and reductants
•Under high temperature conditions in the PIZO furnace, metal oxides are reduced
•Volatile metals exit the process as a gas
•Iron and some other metals go into molten bath
•Remaining materials produce a molten slag
