Separation of Quartz, Feldspar and Mica in Granite

In order to extract quartz, feldspar and mica from unweathered granite, the crushing of granite and the separation of respective minerals were investigated. The heating and quenching of granite was introduced to its crushing process and was found to be favorable for the recovery of mica by magnetic separation.

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).
