Abstract
a presente invenção se refere a um método para o destintamento do papel reciclado, que compreende uma etapa de polpação, e em seguida, uma denominada etapa de flotação, caracterizada pelo fato de que compreende uma etapa de introdução de, pelo menos, um dispersante do tipo poliacrilato, representando a partir de 0,05 a 3,5% em peso dos excipientes minerais do papel reciclado. a presente invenção também se refere à utilização deste dispersante específico durante a etapa de flotação do método de destintamento do papel reciclado.
