Phosphate Mining Today. After a mine site is permitted and reclamation plans are in place, the land is prepared for mining. Endangered species are relocated and measures are taken to protect wetlands and other preservation areas. In addition, systems are put in place to offset any impact to water levels and flow in the surrounding areas.
In organic chemistry, phosphate or orthophosphate is an organophosphate, an ester of orthophosphoric acid of the form PO 4 RRR where one or more hydrogen atoms are replaced by organic groups. An example is trimethyl phosphate, CH 3 3 PO term also refers to the trivalent functional group OPO 3 in such esters.. Orthophosphates are especially important among the various
