Foreign phosphate rock energy storage

How can phosphate rock be recovered?

It has been reported that the phosphate rock has REE concentration ranging from 0.01 to 0.1% and that the concentration is dependent on rock origin as well as phosphate (P 2 O 5) content of the phosphate rock. The REE can potentially be recovered using ion exchange, solvent extraction, and decanter centrifuge.

Is phosphate rock a new Ree resource?

Recommendations for further development of REEs recovery from phosphate rock are given. Generally, phosphate rock contains about 0.05 wt% rare earth elements (REEs) on average. And the world commercial phosphate rock production is estimated to be 250 million tons per year, that makes phosphate rock a potential new REEs resource.

Are phosphate rock reserves growing with demand?

This aspect of reserves growth with demand is currently the case as the demand for fertilizers is increasing due to population growth. Phosphate rock reserves increased from 11 million tons in 1995 via 16 in 2010 to 74 million tons in 2022 (Jasinski, 1996, Jasinski, 2014, Jasinski, 2018a).

Which process is suitable for REE recovery in phosphate rock?

For example, both HNO 3, HCl, H 3 PO 4 processes are suitable for REEs recovery in the case of REEs presented as isomorphous substitution in phosphate rock since REEs in this presented form can easily be decomposed by mineral acids.

What is the value of phosphate rocks?

Generally, phosphate rocks contains 0.046 wt% REEs on average , which means about 125kt of REEs potential yearly production and the value is relative high due to the high HREEs proportion. ii. The cost of mining and processing of minerals has been covered by the industries of phosphoric acid and fertilizers . iii.

What is the leaching efficiencies of phosphorus and Rees?

Wang et al. achieved 90.4% and 98.7% of leaching efficiencies for REEs and phosphorus by attacking phosphate rock with 25%P 2 O 5 returning acid produced from wet-process phosphoric acid with L/S = 10 ml/g ore at 65 °C for 8 h.
