Abstract

En un método para separar cobre y metales pesados de desechos de residuos de incineracion y escorias, los desechos de residuos de incineracion y/o pirolisis, y las escorias, junto con las sustancias con contenido de cloro y/o cloruros, tales como residuos de gases de purificacion de humos, CaCl2 proveniente de la produccion de sosa, sal comun, solventes orgánicos con contenido de cloro, o sedimentos provenientes de procesos de electroplastinado, son calentados por encima de 650 degree C bajo condiciones de reduccion, a partir de lo cual, los cloruros de cobre y los cloruros volátiles de metales pesados, tales como PbCl2 o ZnCl2, son separados en la fase gaseosa.
