Manufacturing of Superphosphates SSP & TSP from Down Stream Phosphates

The present study aims to compare the performance in batch test of TSP and SSP fertilizer manufacturing from different grades of Down Stream phosphate compared to standard qualities. The results showed the technical feasibility of manufacturing these fertilizers from DS rock phosphates tested, however obtaining a TSP according to commercial specifications, requires grinding of phosphate DS to a fineness such as 90% passing 160 μm. The study demonstrated the feasibility of manufacturing these fertilizers from DS phosphates, however, to get fertilizers that comply completely with the commercial specifications it is necessary to grind them such as 90% passes at 160 μm.
