Extraction of potassium from K-feldspar via the CaCl2 calcination route …

 · As much as approximately 41% of the potassium was volatilized in 40 min at 1100 °C. The mass ratio of CaCl 2 /K-feldspar ore significantly affected the extraction. At a mass ratio of 1.15 and 900 °C, the potassium extraction reached 91% in 40 min, while the extraction was reduced to only 22% at the theoretical mass ratio of 0.2.
