In Florida, about 19 Mt of phosphate rock are mined annually and most are used to manufacture fertilizers using a wet process, in which sulfuric acid

How phosphate is mined and processed

Phosphorus in rock is pretty insoluble and thus not directly available to plants. In nature, rock phosphate can become soluble (and available to plants) either by chemical weathering or through the actions of certain types of plants. The solubility also depends on rock type and the pH of the soil; phosphorus is most soluble when contained in sedimentary rocks as opposed to

Yara plays key role in game-changing rare earth elements

The rare earth elements in the phosphate rock used by Yara now ends up in the fertilizer. The elements with names like cerium, thulium and lutetium are not harmful in any way, but have no function as crop nutrition either. The plan is to extract the rare earth elements during the fertilizer production process at Yara Porsgrunn. REEtec has developed a new, ground breaking

Direct leaching of rare earth elements and uranium from

08/03/2019 Phosphate rocks can contain considerable amounts of accompanying uranium and rare earth elements (REEs). Interest to extract these elements during phosphate rock processing to mineral fertilizer is given as both uranium and REEs are valuable and toxic. Recovering these elements is thus advantages from a resource conserving and environmental
