Abstract

Se describe un método para la depresion o sedimentacion de los minerales de ganga a filonianos de silicato no sulfurados, en donde el depresor es ya sea (1) un material polimérico que comprende unidades recurrentes de la formula; en donde X es el residuo de polimerizacion de una acrilamida o mezcla de acrilamidas, Y es una unidad polimérica que contiene grupos hidroxilo, Z es una unidad polimérica que contiene grupos anionicos, x representa una fraccion mol residual de la menos aproximadamente 35%, y representa una fraccion mol residual de aproximadamente 1 a 50% y z representa una fraccion mol residual de aproximadamente 0 a aproximadamente 50%, o (2) una mezcla de polímero y un polisacárido.
