Feb 6, 2022So apatite jewelry is usually confined to earrings and pendants or occasional-wear rings with protective settings. Apatite is also sensitive to heat and acid, so should not be worn when working with chemicals. When crystals of rutile grow in apatite, the stones may display chatoyancy (the 's eye effect) when the gem is cut as a cabochon.

ABSTRACT. In 2000, a reactive barrier was installed on the East Fork of Ninemile Creek near Wallace, Idaho to treat acid mine discharge. The barrier was filled with fishbone derived Apatite IITM to remove the contaminants of concern (Zn, Pb, and Cd) and raise the pH of the acidic mine discharge. Metal removal has been achieved by a combination of chemical, biological, and physical precipitation.
