Abstract

"PROCESSO PARA O TRATAMENTO TéRMICO DE RESìDUOS COM TEOR DE METAL PESADO E óXIDO DE FERRO" Processo para o tratamento térmico de resíduos com teor de metal pesado e óxido de ferro em um forno provido de vários andares sobrepostos, em que resíduos com teor de metal pesado e óxido de ferro são continuamente colocados no forno e carregados no andar mais alto e pouco a pouco transferidos aos andares inferioroes, em que agentes redutores são colocados no andar mais alto e/ou em um dos andares mais abaixo e reagem com os resíduos com teor de metal pesado e óxido de ferro para formar metais pesados e ferro diretamente reduzido, em que os metais pesados são despejados para fora do forno juntamente com os gases de escape e o ferro é despejado juntamente com resíduos dos agentes redutores na área do andar mais baixo do forno de vários andares.
