how to process crude zinc oxide or waelz kiln to higher zinc oxide

  • Waelz Oxide (“WOX”) Home American Zinc Recycling

    Waelz Oxide (“WOX”) WOX (sometimes called crude zinc oxide or CZO) is produced from the recycling of EAF dust in our Waelz Kilns, which is a High Temperature Metals Recovery process designated as Best Available Demonstrated Technology by the U.S. EPA for managing EAF dust, a listed hazardous waste under EPA regulations.
