Abstract

"PROCESSO PARA PRODUZIR AGLOMERADOS COM UMA ESTRUTURA NúCLEO/CASCA" A invenção refere-se a um processo para produzir aglomerados compreendendo uma estrutura núcleo-casca em que: i) aglomerados primários são preparados os quais contêm um primeiro sólido em forma de partícula; ii) um segundo sólido em forma de partícula é aglomerado na presença dos aglomerados primários enquanto adicionando um líquido aglutinante de modo a obter aglomerados do segundo estágio, e opcionalmente; iii) um enésimo (n<242>) sólido é aglomerado na presença de aglomerados do estágio (n-1)ésimo enquanto adicionando um líquido aglutinante de modo a obter aglomerados do enésimo estágio.
