Other benefits to the direct use of rock phosphate are: 1. It is relatively cheap compared to inorganic/chemical phosphorus fertilizers. 2. It is environmentally friendly. As a natural source of phosphorus, it avoids the use of inorganic fertilizers which contribute to green house gas emission during its manufacturing process. 3.

Plants require phosphorus to grow. Phosphorus is an element on the periodic table that cannot be substituted and is therefore vital for producing the food we eat (Steen, 1998).90% of global demand for phosphorus is for food production, currently around 148 million tonnes of phosphate rock per year (Smil, 2000a, Smil, 2000b, Gunther, 2005).. …
The Ardmore Phosphate Project is expected to displace a chunk of Australian and New Zealand imports currently sourced primarily from North Africa. Located around 110 kilometres south of Mt.

The phosphate rock is mined, dried, crushed until 60–70% of the rock is less than 150 μm in diameter, and then continuously fed into the reactor along with sulfuric acid. The reaction combines calcium from the phosphate rock with sulfate, forming calcium sulfate (CaSO 4 ), commonly referred to as gypsum.
