However, unlike other molten salt agents that promote the extraction of K + from K-Feldspar, the Na 2 CO 3 resulted in the extraction of silica instead. XRD analysis of the roasted-acid leach sample was mainly nepheline (NAlSi 3 O 8 ) and kaliophilite (Na(K) AlSiO 4 ) indicating that silica present in Na 2 SiO 3 was extracted.

The molten salt extraction is one of the novel techniques used to extract K from feldspar mineral. Molten salts namely CaCl 2 and MgCl 2 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: CaCl 2) and (Feldspar: MgCl 2). After
