Influence of addition of calcium salts on extraction of potassium from
Abstract. In this article, calcium salts were added into the hydrofluoric acid-sulfuric acid (HF-H 2 SO 4) leaching system, and their effects on the extraction of potassium from phosphorus-potassium associated mineral (mineral deposits containing Ca 5 (PO 4) 3 F (fluorapatite) and KAlSi 3 O 8 (potassium feldspar)) were investigated.

Effect of sintering temperature of potassium feldspar‐limestone
Potassium feldspar (KAlSi 3 O 8) is a typical K-bearing aluminosilicate and represents only one species of feldspars. K-feldspar crystal lattice is composed of corner-sharing and tetrahedral linked in an infinite 3D framework. K acts as a charge-compensating cation in the framework.
