In the case of producers of igneous phosphate rock, for some, ore grades improved in the 30-year period, while for others, technological improvements more than offset ore-grade reductions. The beneficiation rates have fallen as a global average from nearly 72% in 1983 to just about 67% in 2013 (see Table 1).
