Given the findings of the Intergovernmental Panel on Climate Change (IPCC), and the increasing sense of urgency surrounding the COP Climate Summits, attention should be focused on the decarbonization of the sector, rather than any perception of global phosphate rock scarcity. Argus Media chairman and chief executive Adrian Binks said: “This ...

In organic chemistry, phosphate or orthophosphate is an organophosphate, an ester of orthophosphoric acid of the form PO 4 RR′R″ where one or more hydrogen atoms are replaced by organic groups. An example is trimethyl phosphate, (CH 3) 3 PO 4.The term also refers to the trivalent functional group OP(O-) 3 in such esters. Phosphates may contain sulfur in place of
