Abstract

REAGENTE DE BENEFICIAMENTO MINERAL, E, MéTODOS PARA A SEPARAçãO SELETIIVA DE IMPUREZAS DE UMA MISTURA FINAMENTE DIVIDIDA DE PARTìCULAS MINERAIS E PARA A SEPARAçãO SELETIVA DE IMPUREZAS DE ARGILA DE CAULIM. A invenção refere-se a um reagente de beneficiamento mineral, que compreende um ácido alquil hidroxâmico ou seu sal e um tensoativo não-iónico. O ácido alquil hidroxâmico ou seu sal é representado pela fórmula: R-C(=O)N(R")-OM, em que R é um C2-C18 alquila linear ou ramificada, C2-C18 alquenila linear ou ramificada, C6-C20 afila ou arila substituída, C7-C26 aralquila ou aralquila substituída; R" é H, C1-C12 alquila ou aralquila; M é hidrogênio, um metal alcalino, ou um cátion de amónio representado por N¬ +¬(A,B,C,D), em que cada um dentre A,B,C,D, respectivamente, são H ou Cl-C6 alquila ou radicais benzila. O tensoativo não-iónico pode ser qualquer tensoativo não-iónico conhecido, incluindo, mas não limitado a, álcoois etoxilados, ésteres, ácidos etoxilados, (alquil) fenóis etoxilados, alcanolamidas, copolímeros de óxido de polietileno, e misturas destes.
