Phosphorus Removal From Wastewater, Reduce Sludge From

Rare earths form a strong crystalline ionic bond with phosphates, unlike the chemical approach of iron- and aluminum-based coagulants, which do not bind to phosphorus as efficiently. Compared to traditional coagulants, a much lower volume of NeoWaterFX 300 is therefore needed to achieve superior results. In addition to the stronger bond that rare earth elements deliver, these naturally occurring Get price

The Nolans Bore rare

Nolans Bore is a rare-earth element (REE)-U-P fluorapatite vein deposit hosted mostly by the ~1805 Ma Boothby Orthogneiss in the Aileron Province, Northern Territory, Australia. The fluorapatite veins are complex, with two stages: (1) massive to granular fluorapatite with inclusions of REE silicates, phosphates and (fluoro)carbonates, and (2) calcite-allanite with accessory REE-bearing Get price

The Geology of Rare Earth Elements

Rare Earth Ore Classification. Classification of ores related to alkaline rocks is also controversial. Table 2 presents a relatively simple classification that follows analogous categories for deposits related to nonalkaline igneous rocks. Some of the more unusual alkaline rocks that host, or are related to, REE ores are carbonatite and phoscorite, igneous rocks composed principally of Get price
