A review of rare earth minerals flotation: Monazite and xenotime

The effect of sodium silicate on the flotation of non-sulfidic minerals is well-understood. The adsorption of hydrolysis products of sodium silicate on the surface of minerals decreases their floatability and depresses them [43]. Surface activation of monazite by sodium silicate was reported by Beloglazov and Osolodkov [44]. In 1966, …
