##### Where it comes from

Chart: Map of where it comes from

Most phosphate rock formed on ancient sea floors, in North Africa, the Middle East, China and the US. It is dug from big open pits and floated to raise its phosphorus grade.

##### Three things to know

1. In 1974 Morocco's OCP raised its rock price from $14 to $63 a ton within six months.
2. More than 95% of US-mined phosphate rock is turned into phosphoric acid for fertiliser and feed.
3. World reserves of 73 billion tons equal roughly 290 years of 2025 output, so scarcity is about location.

##### The journey

1. 1 **Phosphorite ore**Ancient sea-floor rock or igneous apatite
2. 2 **Open pit**Mined, washed and floated to grade
3. 3 **Phosphoric acid**Rock digested in sulfuric acid
4. 4 **DAP and MAP**Acid combined with ammonia into granules
5. 5 **Farms and feed**Fertiliser and animal feed supplements
