The Extraction of Potassium from Feldspar by Molten Salt Leaching Method with Composite Additives

Abstract:

Effects of ratios of feldspar to CaCl₂ to NaCl, roasting temperature ,roasting time and particle size on the melting-out rate of potassium from feldspar was studied by roasting. Results showed that the highest melting-out rate of potassium reached at 95.35% under the ratio of 1.8:1.1:0.6 of feldspar to CaCl₂ to NaCl, particle size 220mesh, roasting temperature 800°C, roasting time 1h.
