Abstract
Patente de Invenção: <B>"MéTODO PARA O PROCESSAMENTO, EM GRANDES QUANTIDADES, DE SUBSTâNCIAS CONTENDO óXIDO DE CROMO, MéTODO PARA A UTILIZAçãO DAS SUBSTâNCIAS PROCESSADAS, E PRODUTOS QUE COMPREENDEM AS SUBSTâNCIAS PROCESSADAS"<D>. Um método de redução rápida, em grandes quantidades, de escória contendo óxido de cromo e semelhantes, de uma maneira simplificada e sem a necessidade de altas temperaturas. óxidos de cromo são reduzidos com pelo menos um dentre enxofre elementar e compostos de enxofre tendo uma valência menor do que 6. Para uma solução aquosa do componente de enxofre, desejavalmente, seu teor de enxofre é mais do que 0,03% em peso. Como a fonte de enxofre, é preferida escória de alto forno (por exemplo, escória de alto forno gradualmente resfriada, não envelhecida) que e decarregada em grandes quantidades na indústria de ferro. Cr^ 6+^ em óxidos de cromo é reduzido por um dos seguintes modos: (a) Substâncias contendo óxido de cromo são borrifadas com ou imersas em água liberada de escória de alto forno que foi usada em resfriamento de escória de alto forno. (b) Substâncias contendo óxido de cromo são misturadas com escória de alto forno, e então são mantidas em uma atmosfera de ar. Opcionalmente, a mistura é borrifada com água liberada de escória de alto forno. (c) Substâncias contendo óxido de cromo são misturadas com escória de alto forno, e então são tratadas com vapor. (d) Antes do tratamento de redução, substâncias contendo óxido de cromo são de preferência tratadas com vapor. 100 partes em peso de compostos contendo óxido de cromo reduzidos são misturadass com de 0,1 a 90 partes em peso de escória contendo enxofre, e são usadas em vários trabalhos de engenharia civil.
