Abstract
Nouveaux collecteurs pour la flottation de minerais, qui permettent la réparation ou l'enrichissement de certains minéraux même à des pH voisins de 7. Ces collecteurs sont des sulfures organiques du type R-S-R' dont les deux groupes R et R' sont différents et au moins un d'entre eux porte, de préférence, un substituant renfermant de l'oxygène ou du soufre. La proportion de collecteurs est de 10 à 100 ppm par rapport au poids du minéral à faire flotter.
