IHP is the Only Way to Exploit Low-grade Phosphate Rock Raw Material
- A major advantage of IHP over WAP is its ability to use low-quality phosphate rock—this implies a direct and multi-billion ton increase in the volume of phosphate reserves that can be economically exploited around the world.
- The world has a lot of phosphate rock “resources,” by some estimates close to 0.5 trillion tons; however, the large majority of this rock cannot be exploited economically because it is incompatible with the WAP process.
- The WAP process cannot tolerate high levels of Fe, Al and Mg. High levels of these impurities are often the reason phosphate resources have not been mined to date.
- IHP can tolerate high levels of these impurities, about twice what the WAP process can. This means IHP can unlock the value in a large number of these deposits. Several examples include:
- The Georgina basin in Australia estimated to contain 3 billion tons of phosphate rock
- Low grade Egyptian deposits, like Abu Tartur, totaling approximately 3 billion tons
- Offshore deposits like those near Namibia, estimated at 2 billion tons
- Billions of tonnes of phosphate resources are transformed into valuable reserves by IHP.
