Abstract

PROCEDIMIENTO PARA RECUPERAR METALES DE RESIDUOS DE ACERIAS POR REDUCCION CARBOQUIMICA EN HORNO DE PLASMA TERMICO. COMPRENDE SOMETER LOS RESIDUOS DE ACERIAS Y METALURGICOS DE CUALQUIER PROCEDENCIA Y COMPOSICION DE METALES, A UNA REACCION DE REDUCCION EN HORNO ELECTRICO DE PLASMA, EMPLEANDO COMO AGENTE REDUCTOR CARBON EN POLVO, Y COMO FUNDENTE MATERIAL SILICEO, PRODUCIENDOSE TRES PRODUCTOS BASICOS, UNA MASA DE METAL FUNDIDA QUE CONTIENE LOS METALES PESADOS DEL RESIDUO, UNA MASA DE ESCORIA LIQUIDA DE NATURALEZA SILICO-ALUMINOSA Y UNOS GASES REDUCTORES QUE CONTIENEN LOS METALES VOLATILES.
