Potash Feldspar Recovery Process - 911 Metallurgist

29-06-2017  The sulfides, mica, and feldspar were floated in turn and produced a potash feldspar containing the following, in percent: 9.9 K2O, 0.73 Na2O, 0.97 CaO, 24.6 Al2O3, and 61.0 SiO2.

Potassium Extraction from K-Feldspar Ore

13-02-2019  As a potential potash source, K bearing feldspars could be processed with a heat treatment followed by water leaching. This process might present an alternative potash production source and value-added products can be produced from the feldspars. Despite having deep background information, there is still no plant that produces potash from feldspars.

Feldspar - an overview ScienceDirect Topics

The feldspar fuses when it melts, forming a glass matrix. The feldspars are mixtures of potassium alumino-silicate (K 2 O Al 2 O 3 6SiO 2) and sodium alumino-silicate, also known as albite (Na 2 O Al 2 O 3 6SiO 2). Feldspars are naturally occurring substances, so the ratio between the potash (K 2 O) and the soda (Na 2 O) will vary somewhat.
