Beneficiation of rock phosphate fertilisers by mechano-milling - DeepDyve

Mechano-milling is a process where materials are ball-milled at high energy to induce chemical and physical reactions. This study investigated the effect of milling on the properties and agronomic effectiveness of six apatite rock phosphates (RP). The effects of milling were evaluated by X-ray diffraction, BET-N2 surface area measurements, electron microscopy and solubility in 2% citric acid.
