Recovery of Feldspar and Glass Sand from Georgia Waste Granite Fines.

PB234689

Publication Date	1974
Personal Author	Eddy, W. H.; Collins, E. W.; Sullivan, G. V.
Page Count	20
Abstract	Laboratory batch and small-scale continuous flotation processing tests were made on waste granite fines from Lithonia, Georgia, to determine the feasibility of recovering usable feldspar and quartz products by flotation. Two flotation methods were used for the removal of biotite and other iron-bearing minerals. One was in an acid-cationic circuit, and the other in an alkaline-anionic-cationic circuit. Feldspar was recovered using an acid-cationic method. Commercial-grade products were obtained when the remaining ferric oxide was removed from the feldspar and quartz concentrates magnetically. About 42% of the quartz was recovered at glass sand specifications. An effective separation of potash feldspar from the bulk feldspar concentrate was achieved by batch flotation.
