Abstract
Patente de Invenção: <B>"PROCESSO PARA O PROCESSAMENTO DE áCIDO RESIDUAL OBTIDO DA PREPARAçãO DE TiO~ 2~"<D> . Processo para a preparação de gesso bem como de um pigmento de óxido de ferro a partir de ácidos residuais na fabricação de dióxido de titânio segundo o processo de cozimento de sulfato, caracterizado pelo fato de que em uma primeira etapa é efetuada uma neutralização parcial do ácido residual com um composto de cálcio resultando na precipitação e eventual separação direta do gesso; a solução remanescente, em uma segunda etapa é neutralizada sob precipitação de um precipitado contendo Ti, Al,Cr, V e eventualmente contendo Fe(III). A partir da solução contendo sulfato de ferro após separação do sólido, obtêm-se um pigmento de óxido de ferro em uma terceira etapa sob adição de compostos alcalinos bem como de um agente de oxidação.
