Abstract

"MéTODO PARA FABRICAR ESCóRIA CONTENDO óXIDO DE TITâNIO". A invenção presente provê um método para fabricar eficientemente uma escória contendo óxido de titânio a partir de um material incluindo óxido de titânio e óxido de ferro, sendo que se elimina a redução de dióxido de titânio e minimiza-se o consumo de energia elétrica. O método inclui as etapas de: aquecer, num forno redutor, uma mistura de matérias-primas incluindo óxido de titânio, óxido de ferro, e um redutor carbonáceo, ou a mistura de matérias-primas incluindo ainda uma fonte de óxido de cálcio; reduzir o óxido de ferro na mistura para formar ferro reduzido; alimentar a mistura resultante num forno de reaquecimento/fusão para fundir o ferro reduzido e separar o ferro reduzido da escória contendo óxido de titânio; e descarregar e recuperar a escória contendo óxido de titânio do forno.
