Feb 13, 2019· Apatite is a family of minerals centered around fluorapatite, or calcium phosphate with a bit of fluorine, with the formula Ca 5 (PO 4) 3 F. Other members of the apatite group have chlorine or hydroxyl that take the place of the fluorine; silicon, arsenic or vanadium replace the phosphorus (and carbonate replace the phosphate group); and strontium, lead, and other elements substitute for the ...
Apatite is the main source of phosphorous for the making of chemical fertilizers. While apatite is usually recovered from phosphate orebodies as the primary product of a mining exploitation, this paper documents the approach taken to produce a phosphate concentrate as a secondary product from the tailings of a niobium ore concentrator. The conventional desliming/flotation scheme used to ...
Jan 08, 2016· The first commercial production of phosphate rock began in England in 1847. A wide variety of techniques and equipment is used to mine and process phosphate rocks in order to beneficiate lowgrade ores and remove impurities. The eighth chapter of this book deals with mining and beneficiation of phosphate ore. The principle and operating conditions of important parts of manufacturing process ...

The aim of the present study was to compare the effect of a conventional fluoride preparation and of modern calcium phosphate or apatite containing prophylactic products on initial erosive mineral loss in a combined in situ/in vitro setup. Surface alterations and layer formation were visualized electronmicroscopically. 2. Materials and Methods
This concentrate is ground to 90 pct minus 75 µm and leached to dissolve the phosphate. Apatite, Ca5(PO4)3(F, Cl, ½CO3, OH), is the primary phosphate mineral in the phosphate rock. During leaching the apatite is solubilized as H3PO4 and the calcium content of the apatite is . process of phosphate apatite durbanlizards
This study demonstrated a novel method of FeCl 3assisted HTC process for eluting apatite phosphate, fixing phosphate into hydrochar and recovering phosphate as Kstruvite in sewage sludge. The HTC process could promote the transformation of organic phosphate and pyrophosphate to orthophosphate, while FeCl 3 assisted the conversion of AP to ...

vations of intracellular, vesicleenclosed calcium phosphate in developing mouse bone (12), and suggests that an intracellular process may play a role in bone apatite formation. It is dif ficult to observe any such intracellular process, however, as conventional EM preparation techniques, such as glutaraldehyde fixation,
Apatite samples, with carbonate substituted in both the phosphate site (Btype) and hydroxide site (Atype) of hydroxyapatite, were prepared in a twostep process. First, BCAp samples were prepared at moderate temperature (80 – 85 °C) via an aqueous precipitation method at high pH (11–13) conditions with ammonium carbonate as the source ...
