    Rock phosphates must therefore be chemically treated so that the phosphorus they contain is changed into the digestible orthophosphate form (PO4³) During this process, close control of the production parameters is essential to avoid deterioration of the orthophosphate molecule into other unavailable forms of phosphorus, such as pyro and metaphosphate, and to ensure a suitable calcium to
