Researchers Find Phosphate Rock as Source of Rare

Rare earth elements generally amount to less than percent in phosphate rock. But worldwide, about 100,000 tons of these elements per year end up in phosphogypsum waste. That's almost as much as the approximately 126,000 tons of rare earth oxides produced worldwide each year.

iii Abstract Rare earth elements (REEs) are known as strategic and critical elements and, in recent years, have gained great interest as key materials that play an integral role i

Interactions of phosphate solubilising microorganisms

Many microbial species are capable of solubilising insoluble forms of phosphate and are used in agriculture to improve plant growth. In this study, we apply the use of known phosphate solubilising microbes (PSM) to the release of rare earth elements (REE) from the rare earth phosphate mineral, monazite. Two sources of monazite were used, a weathered monazite and mineral sand monazite,
