Abstract

floculantes seletivos compreendem um polímero compreendendo unidades recorrentes de um ou mais monômeros de acrilamida; unidades recorrentes de um ou mais monômeros selecionados a partir de hidroxialquil alquil acrilato, aliloxialquildiol, aliloxietanol, trimetilolpropano alil éter, e 2-hidroxi etil acrilato; e opcionalmente, unidades recorrentes de um ou mais monômeros de ácido acrílico. também são divulgados processos para enriquecer um mineral desejado a partir de um minério compreendendo o mineral desejado e ganga, em que o processo compreende realizar um processo de floculação seletiva na presença de um ou mais dos floculantes seletivos.
