Ch in Flotation A M Gaudin Mem Volume 2 AIME 2:1285-1304
A Bureau of Mines investigation employing an oxidized taconite from the Mesabi Range is discussed and illustrates the selective flocculation-deslime-flotation process developed by the Bureau and used at the tilden concentrator. Concentrates containing 64 percent fe and less than or equal to 5.0 percent sio2 with accompanying iron recoveries of 75 percent were obtained in a 900-pound-per-hour flotation pilot plant.
