Abstract In the present study, a comparison of the amenability of a monazite and xenotime (both rare earth phosphates) sample to treatment via alternative extraction techniques was conducted. Monazite and xenotime concentrates were studied under the effects of organic acids and mechanochemical pre-treatment. Maleic, tartaric, citric and oxalic acids have shown the ability to increase the dissolution of phosphorus in the monazite concentrate. Oxalic acid demonstrated to enhance the release of phosphorus (>30%) at pH
