Monazite Mining. All monazite mining is focused on placer deposits because they are easier to mine and the monazite is often present in higher concentrations than in hard rock deposits. Other heavy minerals that accumulate with monazite include gold, platinum, magnetite, ilmenite, rutile, zircon, and a variety of gemstones. The heavy sands ...

The Hurdtown Apatite Mine is near Hurdtown, New Jersey. The Hurdtown Apatite Mine was closed at the time of data entry with no known plans to re-open. Production size when active was considered to be small. The ore mined is composed of magnetite.
Apatite is the defining mineral for 5 on the Mohs scale. Hydroxyapatite, also known as hydroxylapatite, is the major component of tooth enamel and bone mineral. A relatively rare form of apatite in which most of the OH groups are absent and containing many carbonate and acid phosphate substitutions is a large component of bone material.
In Canada, large glassy Apatite crystals in orange Calcite have come from the Yates mine, Otter Lake, Quebec. Very large crystals also come from Ontario, at Bear Lake in Tory Hill, and at Cardiff, both in Haliburton Co. In the U.S., the state of Maine has several excellent Apatite localities.

Renamed in 1860 from the original apatite of Abraham Werner by Carl F. Rammelsberg to emphasize the chemical composition. Apatite is from the Greek ἀπατάω (apatao), to deceive, as apatite was often confused with other minerals (e.g. beryl, milarite).Rammelsberg added the "Fluor-" prefix in allusion to the dominance of fluorine in the composition.
May 01, 2014· Apatite is mostly used in the production of phosphorus mineral fertilisers as well as in the chemical and pharmaceutical industries.

This is preferable to traditional rare earth ores, as apatite is non-radioactive and does not pose an environmental hazard in mine tailings. However, some apatite in Florida used to produce phosphate for agriculture does contain uranium, radium, lead 210 and polonium 210 and radon. Apatite is an ore mineral at the Hoidas Lake rare earth project.

Dissolution of apatite minerals would ensue immediately upon contact with runoff water. Thus, once runoff occurred in the mining lands, they would be potential sources contributing dissolved P (DP) into water bodies. High DP concentration (0.4–3.0 mg L−1) has been measured in runoff from two reclaimed phosphate mining sites in Florida (Kuo ...
