rare earth flotation collectors

In addition to fatty acids and hydroxamates phosphoric acid esters have also been investigated for use in rare earth flotation Like the former collectors these are primarily anionic in nature and are also thought to chemically adsorb on the mineral surface via a complexation reaction
