摘要

Reagent for mineral beneficiation, and methods for the separation seletiiva impurities from a mixture of finely divided partu00ecculas minerals and for the selective separation of impurities from kaolin clay. The invention relates to a mineral beneficiation reagent, which comprises an acid or its alkyl hidroxu00e2mico salt and a non-ionic surfactant.The acid alkyl hidroxu00e2mico or its salt is represented by the formula: R - C (= O) n (R ") - OM, where R is a linear or branched alkyl C2 to C18, C18 linear or branched alquenila C2, C6 - C20 thin or arila replaced, C7 - C26 aralquila or aralquila replaced; R" is h, C1 - C12 alkyl or aralquila; Is hydrogen, an alkali metal, or ammonium cation represented by nu00ac + n (a, B, C, d)In each of a, B, C, D, respectively, are h or Cl - C6 alkyl radical or benzila. The non-ionic surfactant non-ionic surfactant can be any known, including, but not limited to, ethoxylated alcohols, esters, acids, ethoxylated (alkyl) phenol ethoxylates, alcanolamidas, copolymers of polyethylene oxide, and mixtures thereof.
