2010-10-8igneous apatite and 0.005 to 0.02 percent of sedimentary marine apatite. Marine reworked apatite becomes enriched in uranium to as much as 0.1 percent. This is demonstrated by the greater uranium content of the texturally more complex phases within a single deposit. Uranium can be secondarily leached from or introduced into.

Phosphorus P in runoff can pose a water quality risk in phosphate mine reclamation areas. High dissolved P DP concentrations about 0.43.0 mg L1 in runoff from these areas and high equilibrium P concentrations for the soils led us to hypothesize that P release is controlled by dissolution of apatite rather than by desorption mechanisms.

2011-12-21To keep mining practices from permanently destroying wildlife habitat, all states including Florida, where most phosphate rock is mined, require the reclamation of mining areas. The two stages of reclamation are contouring and revegetation. Contouring is the stage in which the mined land is reshaped to resemble pre-mining topography and drainage.

2018-11-9It has been hypothesized that phosphorus phosphate rock production will peak in 2033-2034 and then production will unavoidably decrease as the reserves are depleted. Because phosphorus is one of the three elements critical to plant growth, dire consequences for world agricultural production and food security are linked to peak phosphate.

The Pedrobernardo-type trend is a limiting case in which Ca-activity in the melt is nearly zero and calcium, instead of phosphorus, becomes the essential structural constituent ESC of the apatite. When this happens, phosphorus starts behaving as an incompatible element that is concentrated in late fluids.
