Abstract

a presente invenção fornece um processo de tratamento de minério de magnetita que contém menos de 15% em peso de sílica sobre o minério total, em que o processo contém uma etapa de flotação (de espuma) na presença de uma composição coletora que contém de 80 a 100% em peso de pelo menos uma alquiletermonoamina e menos de 20% em peso de alquileterdiamina, em que todos os percentuais em peso são baseados no peso total de todos os componentes de amina, e a alquiletermonoamina é alquiletermonoamina com grau de ramificação de mais de 1, em que o alquila contém de 11 a 17 átomos de carbono, e refere-se ainda à composição coletora que pode ser utilizada no processo.
