摘要: A process for producing metal oxide from metal salts includes cleaning a metal salt in a filter. After cleaning, the metal salt is dried in a drying apparatus. Steam is formed in the drying apparatus. The metal salt is preheated in at least one preheating stage. The metal salt is calcined to metal oxide in a fluidized-bed reactor. The metal oxide is cooled. The steam formed in the drying apparatus is recirculated into the filter.
