• ASSESSING THE DESIRABILITY OF MARINE PHOSPHATE

    Marine phosphate mining The mining of phosphate minerals from the seabed. Marine phosphate mining would potentially use Trailing Suction Hopper Dredging technologies (TSHD), which involves dredging sediment from the seafloor and removing a layer of sediment of up to 3 meters deep. A -head of around 11m wide is dragged on the seafloor

  • Phosphate Minerals an overview ScienceDirect Topics

    The primary type of diagenetic phosphorus mineral formation in marine environments is the substitution of phosphate into calcium carbonate minerals such as calcite or aragonite. Microbes contribute to this process by mineralizing organic phosphorus to reactive phosphate, which then substitutes diagenetically into calcium carbonate.
