The majority of the phosphogypsum produced by a fertilizer plant in the Philippines is just stockpiled, which is considered a liability with no commercial prospects. It is important that we find use of this industrial waste byproduct sooner than it becomes an environmental issue. Our study investigated the economic potential of the phosphogypsum by determining its rare earth elements (REE ...

Phosphate rock Tonnage wise, phosphate rock is the most important as compared with the other material; about 120 millions tons of rock are treated annually while only 30 000 tons of monazite and xenotime. However, no production of rare earths from this source is actually conducted. Apatite is the principal constituent of phosphate rock.

In some lowgrade phosphate rock mines, the content of Fe and Al is even higher than that of P2O5, and it is usual that the P2O5 content in phosphate rock is less than the Si and Ca content. In addition, some elements that are very rare in the Earth's crust are found to be relatively abundant (Fig. 1) in phosphate rocks [17].
