Mar 11, 2019 · Phosphogypsum, a source for rare earth elements, is a waste product from phosphate rock mining, is watery at first and forms a crust as it dries. There are a variety of sources for rare earth elements, including hard rock mining and purification from sediments.

Rare Earth Minerals In Phosphate Rock

Rare earth minerals in phosphate rock - spirosurvey.co.za. 2018-5-25 phosphate rock is a general term that refers to rock with high concentration of phosphate minerals, most commonly of the apatite group , monazite: a rare-earth phosphate mineral monazite is a rare phosphate mineral mined from placer deposits for its rare earth and thorium content.

Monazite: A rare-earth phosphate mineral.

Monazite is a rare phosphate mineral with a stone composition of (Ce,La,Nd,Th)(PO 4 ,SiO 4 ). It usually occurs in small isolated grains, as an accessory mineral in igneous and metamorphic rocks such as granite, pegmatite, schist, and gneiss.

Phosphate mineral - Wikipedia

Phosphate rock has high concentration of phosphate minerals, most commonly of the apatite group. It is the major resource mined to produce phosphate fertilizers for the agriculture sector. Phosphate is also used in animal feed supplements, stone preservatives, anti-corrosion agents, cosmetics, fungicides, ceramics, water treatment and metallurgy.

Phosphate Mineral - an overview | ScienceDirect Topics

Depending on whether the percolating water passing through guano reacts with carbonate rocks or clay minerals, Ca-rich or Mg- and Al-rich phosphates will be deposited. Less commonly, the reaction of guano with ore-derived metals or spontaneous combustion of guano can produce some rare phosphate minerals (Fig. 4).

Monazite - Wikipedia

Monazite is a reddish-brown phosphate mineral containing rare-earth metals. To be more specific, it represents a group of minerals. The most common species of the group is monazite-(Ce), that is, the cerium-dominant member of the group. It occurs usually in small isolated crystals.

Geology of Rare Earth Deposits

THE EXTRACTION AND RECOVERY OF RARE EARTH ELEMENTS …

two phosphate minerals, xenotime and monazite, are also principal rare earth element mineral ores, phosphate rock has the potential become an important supplemental source of rare earth elements. It is estimated that in Florida alone, approximately 30,000 tons of rare earth elements are discarded with various phosphate mining waste by-products

The Geology of Rare Earth Elements

The principal concentrations of rare earth elements are associated with uncommon varieties of igneous rocks, namely alkaline rocks and carbonatites. Potentially useful concentrations of REE-bearing minerals are also found in placer deposits, residual deposits formed from deep weathering of igneous rocks, pegmatites, iron-oxide copper-gold deposits, and marine phosphates ( Table 2 ).

Rare-earth leaching from Florida phosphate rock in wet ...

Phosphorite, or phosphate rock, is the most significant secondary rare-earth resource. It contains high amounts of phosphate-bearing minerals along with low contents of rare earth elements (REEs). 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 reacts with phosphates to produce phosphoric acid and …

Locations of Deposits

Almost all phosphorus is mined as phosphate rock (PO4). Deposits are typically found in shales, cherts, limestone, dolomites and sandstone as well as hydrothermal veins or as chemically dissolved phosphate minerals in igneous and metamorphic rocks. One of the worlds largest phosphate deposit is the Phosphoria Formation, located in southeast Idaho.

Jan 01, 2020 · Monazite ((Ce,La,Y,Th)PO4) A rare earth phosphate containing 50–78% REO. It is recovered as a component of heavy mineral sands and is a major source of thorium which imparts radioactive properties to the mineral. Xenotime (YPO4) A yttrium phosphate containing 54–65% REO including erbium, cerium and thorium.
