The characteristics of phosphate rock for upgrading in

2003-1-1  In this investigation, studies were carried out on the process of thermal upgrading of Maz dag (Turkey) phosphate rock in a fluidized bed. The studies involve the effect of the important variables such as process temperature, air flow rate, particle size and attrition of phosphate particles. The calcined product was water-leached.
