Phosphorus is common within geological materials. The average continental crust contains 0.27% P 2 O 5. 1 Phosphorus is the primary resources to produce fertilizer and phosphorous-based products. 2 Phosphorus is neither substitutable nor recyclable, therefore, the total demand must be provided through the mining, beneficiation and chemical processing of phosphate ores.
