phosphate rock nigerian

In June 2011, Royal Boskalis Westminster N.V. was exclusively selected by Chatham Rock Phosphate Limited (CRP) to undertake the detailed design of its offshore rock phosphate nodule project at Chatham Rise. Boskalis was selected following a full review of three scoping studies submitted by global dredging contractors. The technical viability for utilizing Jebel Kurun phosphate reserve in Sudan for the production of a fertilizer grade phosphoric acid is assessed. Statistical analysis has been carried for 56 samples. Phosphate rock has been classified into three main types and then the number of samples representing each type has been identified. Average values for phosphorus pentoxide is 19% and for uranium

Phosphate rock (PR) is an important mineral resource with numerous uses and applications in agriculture and the environment. PR is used in the manufacture of detergents, animal feed, and phosphate (PO 4 3) fertilizers.Leaching or runoff losses from PR products like PO 4 3 fertilizers, animal feeds, and detergents could cause eutrophication of surface waters enriched in PO 4 3 by
