Extraction of Potassium from Potash Feldspar by Ion-exchange
Abstract:
The extraction of potassium from potash feldspar by NaCl,CaCl2,SrCl2 and BaCl2 has been investigated as function of salt kind and calcination temperature.The phase compositions of potash feldspar and its calcinated,and water insoluble substances of NaCl,CaCl2 co-calcinated potash feldspar were analyzed by XRD.The experiment results showed that the order of ion exchange extraction of potassium was Na+ >Ca2+ >Sr2+ >Ba2+,and at calcination temperature over the melting points of NaCl or CaCl2,the two salts gave potassium ion-exchange degree>90% much greater than that calcinated with other salts.
