Feldspar includes potash feldspar and plagioclase, and the potash feldspar and plagioclase contents range from 0 to 14.61% and 0–8%, respectively. The carbonates include calcite, dolomite and siderite, and their contents range from 3.06% to 29.21%.

However, there are many countries which have no soluble potash sources, but natural potash minerals like feldspar, mica, nepheline syenite, glauconitic sand stone and sericite are highly available. Hence, it is a futuristic work, to utilise these available natural sources for the recovery of potash values for fertiliser making.

Potash feldspar is the main mineral component of almost all igneous rocks, and it has important significance for the classification of rocks. Most of the potash feldspar crystals are in the shape of a plate or a plate with an extension of a crystal axis.

Processes for potassium extn. from abundant K-feldspar have recently attracted interest to ensure potash self-sufficiency for developing countries. Concurrently, distiller waste and soda residue formed in the ammonia-soda process (Solvay method) have resulted in serious pollution.

Potassium feldspars are important components of felsic igneous rocks throughout the Upper Midwest. Together with the plagioclase minerals, potassium feldspars form the bulk of many igneous and metamorphic decorative building stones found in the region, including the St. Cloud Granite, Morton Gneiss and Wausau Granite.

Potash feldspar is a kind of inexpensive and widely dis-tributed aluminosilicate mineral, and it has a Mohr hardness of 6, a density of 2.56 to 2.59 g/cm3 and a melting tempera-ture of 1290 °C in that minerals contain impurities such as mica and quartz[9–14].

Complete extraction of potassium was achieved by roasting feldspar with eggshell powder and 1.5 times the stoichiometric amount of hydrochloric acid. The optimized conditions were feldspar to ESP in a ratio of 1:1.8 at 900 °C for 30 min followed by leaching with water.
