  • Studies on extraction of potassium values from

    2014-12-10  The results indicate that mica (biotite), feldspar (orthoclase), and nepheline are the minerals contributing towards potassium values of the nepheline syenite rock. The maximum potassium is found in orthoclase followed by biotite and nepheline. Some of the mica (biotite) minerals are low in potash content which may be due to the effect of weathering.
