A feldspar is typically referred to as 'potash' if there is significantly more potassium than sodium (typically there will be 2-5% Na 2 O ). If the amounts are closer to equal they are termed potash-soda feldspars (or vice versa). Of course, real potash feldspars also have small amounts of CaO, MgO, Fe 2 O 3, etc.

Special Issue Information. Dear Colleagues, Feldspars are anhydrous alumina silicates formed by sodium, potassium, calcium, lithium and sometimes barium and cesium, along with isomorphic combinations of these elements. They make up 60-65% of the earth's crust. In parallel with the development of technology, the use of industrial raw materials ...
In recent years, a deposit containing collophanite and potash feldspar minerals was found in Yichang, Hubei province, China (Liu et al., 2014, Liu, 2009). ... In …
In scientific terms, albite and microcline/orthoclase can form a solid solution. That is, an alkali feldspar can theoretically vary from sodium to potassium as its flux constituent. Soda feldspars actually tend to have at least 30% of their flux as potassium, while potash feldspars usually have at least 15% of their flux as sodium.
Ambitious water-protection goals. At the end of 2021, K+S will discontinue the underground injection of saline waste water in the Werra potash area. From 2028, no more highly mineralized process wastewater is to be discharged into the Werra and by 2030, the volume of saline wastewater is to be reduced again by 500,000 cubic meters per year.

For example, feldspar and quartz are major components of the granite-based ores from which nonferrous metals are extracted. But after the metals are extracted, these silicates are simply thrown away as mine waste (tailings). Researchers suspect these tailings may become the primary source of feldspar and quartz in the future.
Published Sep 27, 2023. Feldspars are important ingredients in clay bodies and glazes.
