Abstract

LA INVENCION SE ORIENTA A LA FABRICACION DE GRANULADOS BASADOS FUNDAMENTALMENTE EN UN CIANURO DE METAL ALCALINO O ALCALINOTERREO A PARTIR DE UNA SOLUCION ACUOSA DEL CIANURO MEDIANTE GRANULACION DE PULVERIZACION EN LECHO FLUIDIZADO. SEGUN LA INVENCION SE UTILIZA VAPOR DE AGUA SOBRECALENTADO COMO GAS DE SECADO. SE PREFIERE HACER CIRCULAR EL VAPOR DE AGUA EN UN CIRCUITO CERRADO Y EXTRAER Y CONDENSAR SOLO EL EXCESO DE VAPOR. EL PROCESO TRANSCURRE CON POCA FORMACION DE GASES DE ESCAPE Y CONDUCE A GRANULADOS DE ALTA CALIDAD.
