Apatite flotation from brazilite-apatite-magnetite ore
Journal of Mining Science, 2013The article reports research findings on flotation of apatite from brazilite-apatite-magnetite ore by domestic and foreign manufacture reagents. The agents Phospholan PE65 and Arcomon SO exhibit higher selectivity as compared to saponified tall oil fatty acids.

More than 25 atomic percent of aluminum can substitute for other cations in the structure of apatite [ A 10 ( X O 4 ) 6 Z 2 ]. Such a synthetic product was obtained by expelling volatile constituents (H

Calcified Tissue International, 1986
Adsorption of water was studied gravimetrically at 23 degrees C in an open system at several relative humidities on a variety of apatitic calcium phosphates including enamel, deproteinized enamel, and bone mineral. The amount of adsorbed water increases linearly with the surface areas of the synthetic apatites and does not appear very sensitive to ...

The objective of this work was to develop nanocrystalline apatite (Ap) dispersed in a chitosan (CHI) matrix as a material for applications in bone tissue engineering. CHI/Ap composites of different weight ratios (20/80, 50/50 and 80/20) and with CHI of different molecular weights were prepared by a biomimetic stepwise route.

La Revue du praticien, 1994
Acute periarthritis is a typical example of apatite arthropathy related to intratendinous calcifications. The attack may be followed by virtually complete radiological disappearance of the calcification. Within the joint one may exceptionally demonstrate the presence of hydroxyapatite crystals in the synovial fluid during a fluxional flare-up of ...
