Nearly 300 million t of phosphogypsum (PG) are produced every year as a byproduct from
phosphate fertilizer production worldwide. Approximately 58% of the PG are stacked, 28 …

Some phosphate rock contains elevated concentrations of natural uranium. China is the
largest phosphate rock producing country in the world and will soon have the largest …

Phosphate rock, pre-concentrated phosphate ore, is the primary raw material for the
production of mineral phosphate fertilizer. Phosphate rock is among the fifth most mined …

Most European countries import phosphate rocks for mineral phosphate fertilizer production.
In 2017, approximately 5.5 million t phosphate rocks were imported into the EU-28 and …

Phosphate rock or phosphorites are minerals that contain phosphorus (P), measured by its
phosphorus pentoxide (P2O5) content at elevated concentrations. In phosphate ore the …

Phosphogypsum (PG) accumulates during wet-phosphoric acid production for fertilizers. In
the Philippines, PG is partly (40%) utilized to produce gypsum walls and cement. This work …

Abstract The Philippines produce some 2.1–3.2 million t phosphogypsum (PG) per year. PG
can contain elevated concentrations of rare earth elements (REEs). In this work, the leaching …

The management of mine waste has become an urgent issue, especially in semi-arid
environments. In this context, and with an aim to inhibit the oxidation of the sulfide tailings of …

ABSTRACT A new ZnO/polystyrene-butadiene (ZnO/PSBN) and aminophosphonate (Ap)
functionalised ZnO/PSBN nanocomposites synthesised via chemical processes. Scanning …

Reactive silica additives, such as clays, can increase the filterability of phosphogypsum (PG)
during wet phosphoric acid production from phosphate rock (PR). In this study, the effect of …
