REE extraction from phosphoric acid, phosphoric acid sludge, and phosphogypsum
Mineral Processing and Extractive Metallurgy, 2015AbstractPhosphate rock is considered a secondary source of rare earth elements (REE), which are usually found in isomorphism substitution with Ca2+ ion. It approximately assays 0·01–0·1% (100–1000 μg g−1). Large tonnages of phosphate ore are mined and processed annually to manufacture commercial grade phosphoric acid indicating that REE extraction from

Feulgen Hydrolysis with Phosphoric Acid
Stain Technology, 1953Sections from rat tissues fixed in a 10% solution of formalin in 90% alcohol were treated with phosphoric acid in concentrations varying from 30 to 85% at room temperature (28°), and subsequently stained with the Schiff reagent. Intense staining of the nuclear material was obtained in 5 to 15 minutes when 40 to 75% phosphoric acid was used. The intense
