Recovery of mercury from contaminated materials - from a wide variety of materials with only small amounts of mercury

Mercury (Hg) is recovered from solid or liquid materials containing one or more oxidizable compounds by passing the material and oxygen (O2) or an O2- containing gas through an indirectly heated zone at a temperature of 400-1100 [deg]C under such conditions that incomplete oxidation occurs. The prod...

More Information
Summary:Mercury (Hg) is recovered from solid or liquid materials containing one or more oxidizable compounds by passing the material and oxygen (O2) or an O2- containing gas through an indirectly heated zone at a temperature of 400-1100 [deg]C under such conditions that incomplete oxidation occurs. The product stream exiting the heating zone contains a condensible Hg-containing phase and a non- condensible phase with a lower Hg content. These phases are separated and the Hg is virtually completely recovered from the condensible phase.
