Feldspar Mining Process | Equipment | Flow | Cases - JXSC

Feldspar can be replaced by other minerals and mineral mixtures of similar physical properties. Minerals that could be used to replace feldspar include pyrophyllite, clays, talc, and feldspar-silica (quartz) mixtures. The abundance of feldspar will make these substitutions unnecessary for the foreseeable future.

Feldspar flotation as a quartz-purification method in ...

The presence of feldspar in sediment samples poses a challenge to the separation of quartz and affects the chemical procedures for extracting the radioactive CNs 10 Be and 26 Al. Additionally, feldspar contamination reduces the 26 Al/ 27 Al ratio, thus hinders the accurate determination of 26 Al by accelerator mass spectrometry (AMS).
