Abstract

LA INVENCION TRATA DE UN PROCEDIMIENTO PARA LA FABRICACION DIRECTA DE GRANULADOS DE CIANURO ALCALINO Y CIANURO ALCALINOTERREO A PARTIR DE UN GAS QUE CONTIENE HCN Y UNA SOLUCION ACUOSA O SUSPENSION DE UN HIDROXIDO ALCALINO O ALCALINOTERREO. LA REACCION SE REALIZA EN UN REACTOR PARA GRANULACION EN LECHO FLUIDIZADO, PULVERIZANDOSE UNA SOLUCION O SUSPENSION DEL HIDROXIDO SOBRE GERMENES DEL CIANURO A PRODUCIR Y CONDUCIENDOSE SIMULTANEAMENTE AL REACTOR UN GAS QUE CONTIENE ACIDO CIANHIDRICO Y EVAPORANDOSE AGUA MEDIANTE UN GAS DE FLUIDIZACION. EL GAS DE FLUIDIZACION PREFERIDO ES VAPOR DE AGUA. LOS GASES DE REACCION DE UN PROCESO DE BMA O ANDRUSSOW PUEDEN SER QUENCHEADOS Y LA MEZCLA DE GAS PUEDE SER EMPLEADA COMO GAS DE FLUIDIZACION. EMPLEANDO UN GAS QUE CONTENGA HCN LIBRE DE CO 2 PUEDEN OBTENERSE GRANULADOS DE CIANURO ALCALINO CON UNA COMBINACION DE PROPIEDADES EXCELENTE, ENTRE LAS QUE SE CUENTA UN CONTENIDO DE CARBONATO ALCALINO Y FORMIATO ALCALINO JUNTOS CON UN PESO INFERIOR AL 0,4 %.
