It is a ceramic grade, high potash feldspar and is available in crude, 200, 325 mesh and chip form. Since 2012 we have been getting independent reports of a reduction in the potash content (below that stated on the data sheet). As with any feldspar, production users should be vigilant to do sieve analysis testing to spot any iron bearing
Study on the Extracting Potassium from Potash Feldspar
However, potash feldspar is found in many parts of the world. Therefore, it is very significant to study extracting potassium from potash feldspar. The studied extracting process was following, the calcium chloride was used as leaching agent, and melted under high temperature, then made potash feldspar be leached so as to extract potassium.
