Phosphate extraction and processing generates large volumes of phosphate mine waste rock (PMWR) that still contains non-negligible amounts of residual phosphate. Due to the increasing demand for phosphorous (P), in particular by the fertilizer industry, PMWR can become a potential resource for P beneficiation if cost-effective …

When phosphate rock is brought out of the ground, it is naturally mixed with unwanted material or gangue. Gangue is removed from the phosphate ore through phosphate beneficiation, which includes screening at varying size fractions, washing, and flotation. During phosphate flotation, producers use Arkema's flotation reagents to selectively ...

In this paper, the beneficiation of rejected phosphate washing sludges (Ps) was investigated using acid leaching methods. Chemical analysis showed that these sludges are a low-grade ore (15.84% P2O5). The optimum milling parameters have helped to increase the P2O5 grade to 18.51%. Then, the effects of three different organic acids …

Chemical Processing of Phosphate. The phosphate mineral as it exists in the ground is not soluble and is hard for the plant to access. To provide the plant with the phosphate it needs, in a form it can take up through its roots, the phosphate rock is converted to phosphoric acid. It is that acid that is used to make fertilizer.
