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.

The industrial phosphate layer in the Akashat area ranges in thickness between 9 and 15 m with an average of 11 m. The industrial phosphate bed is gray, oolitic, well sorted, fine grained, medium in hardness, friable at its upper parts and containing hard phosphatic limestone in the middle part. The average P2O5 content lies between 20 and 22 %.

A new rock phosphate beneficiation plant is planned in Khatam, Meghnagar, Jhabua, Madhya Pradesh. The project involves constructing a plant with a 70 T (rated) and 77 TPH (design) feed capacity at an estimated cost of Rs.2299.8 million. Construction is set to begin in June 2024 and conclude by September 2025. As of …

The first commercial production of phosphate rock began in England in 1847. A wide variety of techniques and equipment is used to mine and process phosphate rocks in order to beneficiate low-grade ores and remove impurities. The eighth chapter of this book deals with mining and beneficiation of phosphate ore. The principle and …
