Phosphate ores were first mined in relatively small amounts in the mid-1840s in England, France and Spain and in the 1860s in
Phosphate rock of 70 to 75% BPL, or as high as is reasonably obtainable, is finely ground in a ball mill and then mixed with cooled recycled phosphoric acid-gypsum slurry in a digestion tank (Figs. 10.3 and 10.4).At this stage the only reaction which occurs is between acid and any carbonates present in the rock, and between phosphates and low concentrations of sulfuric acid which may be
High grade rock phosphate (Hgrp) coming from the main supplier of rock phosphate. Hgrp is vital because, historically, almost all producers of fertiliser and foods use the same processes. as the Hgrp has limited availability across european countries, in some cases companies have no choice but to use low grade rock phosphate (lgrp). this is where ecophos come into the picture; with their new
