Abstract

"COMPOSIçãO AGLUTINANTE E PROCESSO PARA AGLOMERAR MATERIAL PARTICULADO". A presente invenção refere-se a um processo para produzir péletes contendo óxido de ferro, em que as partículas de óxido de ferro finas são aglomeradas na presença de um aglutinante inorgânico e/ou orgânico e um aditivo aglutinante que serve para melhorar a resistência ao preaquecimento dos péletes. O aditivo aglutinante pode ser um composto contento boro ou fluoreto de cálcio. A invenção é particularmente adequada para aglutinantes orgânicos.
