Abstract

METODO DE RECUPERAR METALES COMBINADOS A PARTIR DE ESCORIA LIQUIDA, POR REDUCCION CON UN AGENTE REDUCTOR CARBONOSO. SE TRATA LA ESCORIA LIQUIDA EN TANDAS EN UN HORNO, ESTANDO CONSTITUIDAS LAS PAREDES POR TUBOS REFRIGERADOS POR AGUA. SE INSUFLA POLVO DE CARBON A TRAVES DE UNA PLURALIDAD DE TOBERAS DISPUESTAS EN LA PARTE INFERIOR DEL HORNO, JUNTO CON AIRE EN DEFICIENCIA ESTEQUIOMETRICA. LA ENERGIA TERMICA REQUERIDA PARA MANTENER LA TEMPERATURA Y EFECTUAR LA REDUCCION Y LA SULFURIZACION SE PROPORCIONA INSUFLANDO GAS PRECALENTADO EN UN GENERADOR DE PLASMA POR DEBAJO DE LA SUPERFICIE DEL BAÑO DE ESCORIA, TRAS DE LO CUAL EL VAPOR DE LOS METALES VOLATILES SE CONDENSA DE MANERA CONOCIDA EN UN CONDENSADOR, RECOGIENDOSE LOS METALES Y SULFUROS NO VOLATILES PRODUCIDOS EN FORMA DE PEQUEÑAS GOTAS FUNDIDAS A LAS QUE SE DEJA QUE SE SEDIMENTEN SEPARANDOSE DE LA ESCORIA.
