how can i separate feldspar from quartz? | Yahoo Answers

May 05, 2007 · There are ways to separate feldspar from quartz. You could try electrostatic separation. Or you could try froth flotation but you must get the conditions just right. If you don't the flotation agent (Cytec 3030C promoter is a good one) mistakes the quartz for feldspar and the separation isn't effective.

flotation separation of feldspars from quartz. AbstractThis paper reviews the application of flotation for the separation of feldspar from the other minerals with which it naturally occurs (such as quartz, clay minerals, mica, ilmenite, rutile, anatase and magnetite) as well as the separation of the individual feldspar minerals themselves.
