Process On Feldspar

Molten salts namely CaCl2 and MgCl2 have been used (Fisher Scientific) for the trapping of K from the feldspar mineral. The ratio of feldspar to flux is varied from 1:1 to 1:10 (Feldspar: CaCl2) and (Feldspar: MgCl2).

Common acid leaching methods for potassium extraction are the introduction of phosphate ore, fluorosilicic acid, fluorite and other fluorine-containing substances, to destroy the stable structure of potassium feldspar (Ding, 1996).Sun et al. (2011) established a co-leaching reaction system of phosphate rock, potassium feldspar and phosphoric acid.. At 250 °C for 3 …

The roasting process between feldspar and calcium chloride prepared from ESP and HCl is a fluid− solid reaction. At the eutectic point of the temperature, calcium chloride melts and acts as the fluid and feldspar as the solid. Particles of potash feldspar were assumed to be spherical in shape, and shrinking core model equations are utilized ...
