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-N 2 surface area measurements, ...

2019-4-30 Earlier the original source of phosphorus (P) fertilizer was bones; as time passes, the supply of P fertilizer will get exhausted. Today, rock phosphate is the only raw material in the form of P fertilizers. There are two types of rock phosphates: igneous and sedimentary; both have the same phosphate mineral, i.e., calcium phosphate of apatite group.

2020-9-1 1. Introduction. The 800% price spike in phosphorus fertilizers in 2007–2008 sent a shock wave through the markets and led to a significant increase in food prices (Cordell and White, 2011).It also shifted attention to phosphorus (P) as a scarce resource and prompted the emergence of a “peak phosphorus” discourse, centred around global scarcity of phosphate rock (PR) as source for ...
