Abstract
Sposób redukcji stężeń siarczanów, metali i arsenu w kwaśnych wodach kopalnianych przez dodawanie do nich ośmiowodnego wodorotlenku baru do poziomów dopuszczalnych dla ścieków przemysłowych wprowadzanych do wód i gleb i dodawanie 10% wag. kwasu octowego polega na dodawaniu ośmiowodnego wodorotlenku baru zmielonego do frakcji < 0,06 mm, w ilości niestechiometrycznej odpowiadającej 65% stechiometrycznej wartości teoretycznej obliczonej dla określonego stężenia siarczanów w kwaśnej wodzie kopalnianej do 1 dm3 próbki kwaśnej wody kopalnianej następnie krótkim mieszaniu całości co 24 godziny przez 96 godzin, dodawaniu do 0,4 ml/l 10% wag. Kwasu octowego i krótkim mieszaniu całości co 24 godziny przez 72 godziny.
