Abstract

La presente invención se refiere a un método y aparato para separar metales tóxicos no deseados, tales como Zn, Pb y Cd, de materiales que contienen hierro mediante: sinterización de una mezcla de dichos materiales (típicamente incluyen polvo de EAF y cascarilla de laminación) con partículas carbonosas para formar bolas sinterizadas resistentes; precalentamiento de dichas bolas en una atmósfera no reductora, si es necesario, para conseguir una temperatura elevada generalmente por encima de la temperatura de vaporización de los metales no deseados, pero por debajo de la temperatura de adherencia de dichas bolas que contienen hierro (que típicamente está por debajo de las temperaturas de vaporización de dichos metales no deseados en su forma de óxido), alimentación de las bolas a dicha temperatura elevada en un reactor de reducción; hacer fluir gas reductor caliente por dichas bolas para volatilizar dichos metales reducidos no deseados y llevar los metales volatilizados fuera de dicho reactorde reducción, dejando las bolas que contienen hierro en gran parte separadas de los metales no deseados y listas para descargar y eliminar de forma segura y/o útil o volver a usar; y finalmente enfriamiento del gas de descarga del reactor para separar los metales no deseados solidificados resultantes (típicamente en su forma de óxido que resulta de un enfriamiento con agua).
