Phosphate is an important volume commodity, the world’s largest exporter being Morocco, and exported in its natural rock condition in large quantities from the South-Eastern United States; North and West Africa (from Tunisia round to Togo); Northern Russia (from which source it is known as Apatite Ore); the Red Sea; and from Christmas Island (Indian Ocean) and Nauru Island (Pacific), much of these Island’s production destined for Australian and New Zealand markets.
Phosphate rock consists largely of calcium phosphate. used as a raw material not only for phosphatic fertiliser, but indirectly for all commercial phosphorus chemicals.
Phosphate is harmless but can be extremely dusty, and will cake and harden if wettened. Although Phosphate has a low angle of repose, once the stow has settled it is unlikely to shift at sea. Di-Calcium Phosphate is considerably lighter than the parent mineral, and is useful as an animal feed additive.
Phosphate Stowage Factor:
- Calcium Phosphate Bulk Stowage Factor 25
- Di-Ammoniurn Phosphate (DAP) Bulk Stowage Factor 42/45
- Di-Calciurn Phosphate Bulk Stowage Factor 55/60
