Phosphate Rock — Raw Material for Phosphoric Acid & Direct Application
Phosphate rock is the fundamental feedstock for the global phosphorus fertilizer chain, feeding wet-process phosphoric acid plants that produce MAP, DAP and TSP. Our export grade carries 28–32% P2O5 with cadmium capped at 40 ppm for EU-compliant fertilizer production. Particle size 0–10 mm suits both acid plant grinding circuits and direct soil application on acidic pastures. Vessel parcels from 25,000 MT.

Vessel Logistics
Phosphate rock loads in gearless bulk carriers at rates of 10,000–20,000 MT/day at major export terminals in North Africa and the Middle East. Moisture below 5% prevents cargo shift during ocean transit. FOB loading; CFR/CIF to phosphoric acid plant jetty or direct-application market. HS 2510.10.
FAQ
What P2O5 grade is optimal for phosphoric acid production?
Most sulfuric acid attack plants specify 28–31% BPL (bone phosphate of lime) rock for optimal acidulation efficiency. Higher-grade rock (32%+) commands premium but reduces sulfuric acid consumption per tonne of P2O5 extracted.
Why is cadmium content limited to 40 ppm?
EU fertilizer regulations cap cadmium in finished fertilizers, forcing acid plants to source low-Cd rock. Moroccan and Egyptian deposits typically meet 40 ppm; some Chinese sources exceed limits and require blending.
Can phosphate rock be applied directly to soil?
Yes, on acidic soils below pH 5.5 where rock phosphate weathers slowly, releasing P over multiple seasons. Direct application is cost-effective for permanent pastures but too slow for annual cropping systems.
