Methods of extracting the interlayer K in micaceous minerals with NaTPB solutions were modified to maximize the extraction of K from muscovite. In the method adopted, 0.500‐g samples were placed in 10 ml of 2 n NaCl‐0.2 n NaTPB‐0.01 m EDTA solution at 25C, and the precipitated K was separated with a boiling 0.5 n NH 4 Cl solution that contained HgCl 2 . Even with this method, muscovite released its K much slower than did biotite. However, it was possible to remove 96% of the K in <10µ muscovite in 16 weeks. This was also the maximum amont of K that was extracted.
