Selecting A Phosphoric Acid Process Di, Hemi, Amp;
A hemi plant normally has lowest capital cost for a new plant, because it usually avoids rock grinding (except with pebblesized rock), it requires much less (if any) evaporation of acid, cooling water is minimized, there is no 27 p205 acid to handle, and product acid clarification is usually unnecessary.
Method For Conducting Wet Grinding Of Phosphate Rock In A
A method and system for conducting wet grinding of mined phosphate rock before utilizing the same for the production of phosphoric acid by the wet process method, the method comprising the steps of: (1) wet grinding the phosphate rock in a medium of fresh water at a first stage so as to form a fresh water slurry comprising ground rock and fresh water, (2) sending the fresh water slurry from.
