The non-isothermal kinetic method was used in this manuscript to obtain the reaction models by fitting the reduction ratio of low-grade phosphate ore and the volatilization ratio of phosphorus. And the reaction mechanism of vacuum carbothermal reduction of low-grade phosphate was investigated by combining XRD, SEM, EDS, …
Phosphorus is an essential element for plant and animal nutrition. Most phosphorus is consumed as a principal component of nitrogen-phosphorus-potassium fertilizers used on food crops throughout the world. Phosphate rock minerals are the only significant global resources of phosphorus. The United States is the world's leading producer and ...

Phosphates, compounds of the element phosphorus, are produced from relatively abundant supplies of phosphate rock. The major use of phosphate is to supply phosphorus, one of the three essential plant foods—nitrogen, phosphorus, and potassium. Phosphate rock extraction from its ore, and its subsequent conversion into fertilizer …
The form of a phosphate mine waste rock pile depends on two criteria: the disposal method (top-down or bottom-up) and the land surface (flat or horizontal) (Blight, 2009).Different configurations of the mentioned criteria are illustrated in Fig. 3.The top-down disposal method involves discharging waste rock over an advancing face (Fig. 3 A–C …
