Leaching kinetics of potassium and aluminum from phosphorus-potassium
Phosphorus-potassium associated ore used in the experiment was obtained from Yichang City of Hubei Province, and its chemical composition of the ore was listed in Table 1 [26].The main mineralogical phases of the ore are quartz (SiO 2), K-feldspa and fluorapatite (Ca 5 (PO 4) 3 F), and the molar ratio of aluminum and potassium of …
