Froth Flotation. 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.
