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.PROCEDURE FOR THE RECOVERY OF METALS FROM WASTE OF STEELS BY CARBOCHEMICAL REDUCTION IN A THERMAL PLASMA FURNACE. IT INCLUDES SUBMITTING THE RESIDUES OF STEEL AND METALLURGICS FROM ANY PROVENANCE AND COMPOSITION OF METALS, TO A REACTION OF REDUCTION IN ELECTRIC PLASMA OVEN, USING AS A SOUND MATERIAL SILICEO, PRODUCING THREE PRODUCTS MELTING CONTAINING THE HEAVY METALS OF THE WASTE, A MASS OF LIQUID SLAG OF A SILICON-ALUMINUM NATURE AND SOME REDUCING GASES CONTAINING VOLATILE METALS.
