The process of mining and processing apatite varies depending on the type of deposit and its location. Here's a general overview of how apatite is typically mined and processed:
Apatite is an important phase in environmental remediation of contaminated groundwater in a process known as PIMS (Phosphate Induced Metal Stabilization; Wright and Conca 2002), a rapidly growing area of apatite science. In the PIMS process, a permeable reactive barrier of apatite is constructed through which contaminated groundwater will flow.

Over the years, the company has mined and ...
The International Mineralogical Association refers to the mineral as Apatite-(CaOH). This distinguishes it from the other two variants of Apatite, Apatite-(CaF) [Fluorapatite] and Apatite-(CaCl) [Chlorapatite]. Erionite Tiny crystals of Erionite can be damaging to human health.

This process was started and used by Molycorp, Inc. until 1995 to recover REEs from the mountain pass mine in CA. The process included one stage of calcination at 600–700 °C and leaching with hydrochloric acid. The calcination process was to remove the gaseous hydrofluoric acid (HF) and oxidize the feed . This process has a main …

The processing route of xenotime is similar to that of monazite. 2.5.2 Ion Adsorption Clays. Commercial mining and processing of these types of ores are currently exercised only in China. The REO assay in this ore is too low, and it lies around 0.05–0.2%. Therefore, ore beneficiation does not have much role in the processing route.
Typical processing involves mining the ore and beneficiating through sizing and flotation to produce a "phosphate rock" concentrate containing over 29 pct P2O5. This concentrate is ground to …
The phosphorus journey begins with the extraction of primary phosphorus in the form of phosphate in the form of apatite from the ground via open pit mining and in some rare cases underground mining methods. The easier, simpler to process ore bodies have long been depleted leaving the more complex ores for today's metallurgists to deal …

In some cases, these properties can be very important for ore processing and metallurgy, especially in case of mining of minerals for phosphate fertilizers (content of cadmium or strontium is critical), or if by-product elements are recovered, e.g., REE in apatite (Gilbert, 2009; Golev et al., 2014) and indium in sulfide minerals (Frenzel et al ...
