On the Modelling of Phosphate Rock Acidulation Process
Phosphate rock particle size is an important factor in the acidulation process. The rock has to be fine enough to allow total dissolution of P 2 O 5 values. The dissolution kinetics are slow enough to be measured as shown in Fig. 1. Generally, more than 90% of the rock is decomposed in less than five minutes.Web
