The properties of the rare earth nitratetributyl phosphatewater system that indicate its possibilities as a solvent extraction system have been studied by many investi
The acidulation of phosphate rock, behavior of uranium and rare earths, influence of iron and effect of humic matter in the sulphuric acid process and the nitric acid process is discussed Uranium extraction from the phosphoric acid by acidic organophosphorus esters is discussed in detail.
Mt Weld, Western Australia. The Mt Weld Central Lanthanide Deposit (CLD) is one of the highest grade rare earth deposits in the world. Mt Weld also hosts the undeveloped Duncan (rare earth), Crown (niobium, tantalum, titanium, rare earths, zirconium) and Swan (phosphate) deposits.
deposits by analyzing samples directly for phosphorus (P), identifying zones of phosphate rocks rich in rare earth elements (REE) and delineating zones with unacceptable levels of .
Phosphate rock (PR) is an important mineral resource with numerous uses and applications in agriculture and the environment. PR is used in the manufacture of detergents, animal feed, and phosphate (PO43–) fertilizers. Leaching or runoff losses from PR products like PO43– fertilizers, animal feeds, and detergents could cause eutrophication of surface waters enriched in PO43– by these losses.

This statistic depicts the distribution of rare earth production worldwide by country as of 2017. At that time, China produced a percent share of the total global rare earth mine production ...
rock as phosphatic if it contained 10 to 100 times or more phosphate than normal. There are small, local accumulations of high phosphate sediments, sedimentary rocks, pellets, and nodules, but this chapter will be concerned with large volume phosphate sedimentary rocks, generally called phosphorites.
Phosphate mineral: Phosphate mineral, any of a group of naturally occurring inorganic salts of phosphoric acid. Phosphates can be grouped as: primary phosphates that have crystallized from a liquid; secondary phosphates formed by the alteration of primary phosphates; and rock phosphates formed from phosphorousbearing organic material.
It is found that the total content of rare earth elements in the phosphate rock is about wt%, amongst which Y, La, Ce, Pr, Nd and Sm are the main rareearth components and .
Abstract. Sixtythree samples representing the phosphorite deposits of the AlKora province in northwest Jordan are analyzed for their major and certain trace elements including the rare earth and uranium.
Of the 17 recognised rare earths, 15 are present in Chatham Rise rock phosphate nodules, as well as varying concentrations of other valuable minerals including nickel, cobalt, chromium, vanadium ...
Rare earth elements (REE) are either housed in exotic REE minerals that sporadically populate the host rock or they occur as ionic substitutions in the crystal structure of existing rockforming minerals. The genesis of REEs in carbonatite rocks can result in intricate mineralogical textures between REE minerals, host rock minerals, and minerals formed by later processes.
