· The separation of quartz OSL from a mixed quartzfeldspar sample relies on the fact that the TROSL shapes (and thereby the luminescence lifetimes) of quartz and feldspar are different. To examine whether the lifetime(s) in quartz are sample specific or whether they are universal, the TROSL curves from 30 quartz samples of various geological origin, of which some were heated material, were

· In the conventional flotation separation of feldsparquartz, hydrofluoric acid is used to suppress quartz and activate feldspar, and a long chain amine salt (acetate or chloride) is used as a collector. The bulk of amine collectors used in current feldspar operations are applied as the watersoluble acetates of the freebase amines.

Separation Procedures For The Mica. After being rinsed, if the sample contains feldspar and mica it will be frothed. to efficiently separate feldspar and mica from quartz, we have developed a procedure that makes feldspar and mica hydrophobic and the quartz becomes hydrophilic. by adding a carbonated solution to the sample, we can separate up to 95 of the feldspar.

In order to improve the purity or the whiteness of feldspar, flotation [3,4,5] and magnetic separation are typically used to remove associated minerals (such as quartz, and darkcolored minerals rich in iron) from feldspar [6,7,8]. Traditionally, there are two main flotation separation processes to remove quartz from feldspar. The first one is hydrofluoric acid flotation, which uses hydrofluoric acid (HF) or fluoride
