Abstract

COMPOSIÇÃO E MÉTODO PARA DESIDRATAÇÃO DE SUSPENSÕES AQUOSAS. Composições e métodos são fornecidos para a recuperação de minerais a partir de suspensão mineral, como a cal gerada nos processos de pulpação Kraft. Mais particularmente, a composição compreende co-polímeros de polialcoxilato, alcoxilatos de alquilenamina, e opcionalmente tensoativos aniônicos, que quando adicionados ao processo de desidratação mineral, auxiliam na recuperação do mineral.
