بيت /Concentration And Plant Design Of Abu Tartur Phosphate Rock
The results indied that heavy metal content was low in Abu Tartur phosphate compared to imported rock and was below the permissible limits with the exception of lead which was higher in local phosphate deposits than the imported rock samples. Phosphate rock is a source of heavy metal pollution (air, soil, water, food chain, etc.) therefore requires removal from the rock prior to its use ...

This paper describes a new approach in the modeling of the dissolution of phosphate rock and its subsequent conversion to phosphoric acid (H3PO4) after it has been treated by sulfuric acid in a continuously stirred tank. The reactor is considered as a set of interconnected modular cells of uniform bulk liquid phase concentration and temperature.
