Abstract
Patente de Invenção: <B>''PELETIZAçãO MINERAL''<D>. A presente invenção é direcionada a um processo de preparação de péletes de mineral queimados misturando-se material de mineral particulado com umidade e aglutinante compreendendo polímero orgânico substancialmente solúvel em água para formar uma mistura peletizável úmida, peletizando-se a mistura úmida por um processo de revolvimento para formar os péletes frescos e queimando os péletes frescos, caracterizado pelo fato de que o aglutinante compreende silicato de metal alcalino em uma quantidade de peso seco que é ou (a) acima de 0,13% com base na mistura úmida ou (b) acima de 0,08% com base na mistura úmida e pelo menos três vezes o peso seco de polímero orgânico substancialmente solúvel em água.
