Synoptic view on P ore beneficiation techniques
Phosphorite exploitation especially agricultural consumption majorly relies on the availability of phosphorous (P). Mostly, the plant availability of P in soil is influenced by associated mineral such as it depends on Magnesium (Mg) and Calcium (Ca) when soil has pH > 8 and by Iron (Fe) and Aluminum (Al) when soil has pH < 5.5.
