Abstract (en)
[origin: EP0908673A1] A carbon-rich heavy metal-containing slag and/or ash from waste thermal treatment is heated in a rotary kiln to reduce its heavy metal content to metallic form and evaporate volatile heavy metals. Slag and/or ash, from waste thermal treatment, is processed by (a) pyrolyzing, gasifying or partially incinerating the waste (1) to form a carbon-rich heavy metal-containing slag and/or ash (8); (b) heating the slag and/or ash (8) in a rotary kiln (6) to below its melting temperature to convert the heavy metal content into the metallic form by reduction with the carbon content and to convert the volatile heavy metals into the gaseous phase which is entrained with the flue gas (9) from the kiln (6); and (c) discharging a heavy metal-depleted slag (15) from the kiln (6).
