geochemistry Why does phosphate rock contain

Phosphate rock does not become enriched with uranium/thorium/radium until the extraction process separates and concentrates these metals When the phosphate rock is treated with sulfuric acid, the uranium and thorium become concentrated in the aqueous phase while radium concentrates into the gypsum A lot of other heavy metals also get

Thorium Production

To separate the thorium from this solution advantage is usually taken of the fact that thorium phosphate is less soluble in dilute acid than the phosphates of the other metals that are present Consequently, by partially neutralising the acid solution a precipitate is obtained rich in thorium phosphate As a neutralising agent magnesia has
