Collector for the flotation of carbonates

Collector for the flotation of carbonates

The invention relates to a collector for the separation by flotation of carbonates contained in non-sulfurous minerals, particularly phosphoric rock, comprising at least one phosphoric ester of formula (I) wherein, - R1 represents H, CH3 or C2H5, - R2 represents a linear or branched alkyl or alkenyl...
