Abstract
La présente invention concerne un procédé de traitement des minerais siliceux non sulfurés avec une composition de collecteur qui comprend un composé phosphate de formule (I) dans laquelle R représente un groupe hydrocarboné linéaire ou ramifié, saturé ou insaturé contenant 1 à 24 atomes de carbone ; A représente un motif oxyde d'alkylène ; Y représente H, Na, K ou un ion ammonium ou ammonium alkylé, n vaut 1 à 3, p vaut 0 à 25 et X est choisi parmi les mêmes groupes que R-Ap- ou Y. La présente invention se rapporte également à une composition de collecteur contenant le composé phosphate de formule I en tant que collecteur primaire en association avec un collecteur secondaire et à une composition de pâte contenant le composé phosphate de formule (I).
