ASSESSING THE DESIRABILITY OF MARINE PHOSPHATE MINING

Phosphorus is a key nutrient that is essential to all life forms In its elemental form phosphorus cannot be absorbed into fauna and flora it is rather taken up as various phosphate compounds In South Africa apatite ore is the most common source of phosphate rock and has been mined since the mid 1900s in Phalaborwa Limpopo DMR 2008 .
