Waste rock reprocessing to enhance the sustainability of phosphate
Phosphate rock is extracted from open-pit and underground mines, depending on the geological and morphological properties of the phosphate ore. Generally, the extraction from open-pit mines generates dust emissions and produces large quantities of mine waste with 1–12 tons of waste extracted per 1 ton of phosphate ore (Taha et al., 2021).

Leaching of phosphorus from phosphate tailings and extraction of
In the past few decades, a large amount of high-grade phosphate rock in China has been exploited and the resultant phosphate tailings have an extremely low rare-earth element content. Therefore, the extraction of rare-earth elements is not economic, in comparison, the large-scale resource utilization of phosphate tailings is a critical problem.
