Abstract
DONDE EL PROCEDIMIENTO COMPRENDE LA INTRODUCCION DE UNA CARGA A GRANEL PULVURENTA ENTRE DOS ELECTRODOS DE UNA CELULA ELECTROLITICA, ESTANDO LOS ELECTRODOS CONFIGURADOS DE MANERA PERMEABLE A LOS LIQUIDOS Y DICHA CARGA ES RECORRIDA POR EL ELECTROLITO VERTICALMENTE CON RESPECTO A LAS SUPERFICIES DE LOS ELECTRODOS. DICHA CARGA CONTIENE: a) W, Mo, Re Y SUS ALEACIONES, Y COMO ELECTROLITO SE EMPLEA UNA SOLUCION ACUOSA DE HIDROXIDO ALCALINO; o b) Ni, Co y/o Cr, COMPONENTES VALIOSOS COMO Hf, Ta, Nb, Mo, W, Re y/o METALES DE PLATINO, Y COMO ELECTROLITO SE EMPLEA UN ACIDO INORGANICO ACUOSO. LA CELULA ELECTROLITICA ESTA CONSTITUIDA POR UNA CARCASA ELECTROLITICAMENTE AISLANTE, Y POR DOS ELECTRODOS PARALELOS, PRESENTANDO AL MENOS UN ELECTRODO UNA ESTRUCTURA QUE COMPRENDE UNA PLACA PERFORADA DE SOPORTE, UNA PLACA DE ELECTRODOS DOTADA CON PERFORACIONES Y UN PANO FILTRANTE DISPUESTO ENTRE DICHAS PLACAS, ESTANDO APANTALLADA FRENTE A LA CELULA LA ESTRUCTURA CATODICA POR MEDIO DE UN SEPARADOR; Y SE PROVEE POR EL LADO DEL CATODO UNA CAMARA VERTICAL PARA EL ELECTROLITO, Y POR EL LADO DEL ANODO UNA CAMARA DE ACUMULACION PARA EL ELECTROLITO, UN CONDUCTO DE RECIRCULACION DISPUESTO FUERA DE LA CELULA, Y MEDIOS PARA EL RECICLO DEL ELECTROLITO DESDE LA CAMARA DE ACUMULACION HACIA LA CAMARA VERTICAL
