A bstract The beneficiation of the feldspathic waste from a titanium mine near Roseland, Virginia, is discussed. This waste, which is mainly sodic plagioclase, quartz, and an iron‐bearing mineral, gedrite, contains about 5.3% of Fe 2 O 3 . By magnetic concentration, 73% of the feed was recovered in a feldspar‐quartz mixture with an iron content of 0.81% of Fe 2 O 3 . From this nonmagnetic product, between 85% and 90% of the feldspar with an iron content of 0.41 to 0.52% of Fe 2 O 3 was recovered by agglomerate tabling and flotation. Examination of the feldspar concentrate, however, showed that iron stains and iron‐bearing impurities of microscopic size in the feldspar prevented the separation of a feldspar concentrate with less than 0.36% of Fe 2 O 3 .
