Abstract
a presente invenção refere-se a um método de produção para minério de ferro de baixo teor de enxofre, em que minério de ferro contendo em excesso de 0,08% não mais do que 2% de enxofre são submetidos à flutuação, produção de minério de ferro em que o teor de enxofre foi reduzido a 0,08% ou menos. neste método de produção, durante o processo de flutuação, (1) um composto com base em xantato e um sal de um composto de amina são usados como coletores, (2) um composto com base em xantato é usado como um coletor, e uma substância que libera íons de enxofre em água é usada como um ativador, ou (3) um composto com base em xantato e um sal de um composto de amina são usados como coletores, e uma substância que libera íons de enxofre em água é usada como um ativador.
