Abstract
Laboratory and pilot plant studies showed that supergrade iron ore concentrates (containing less than 2 percent sio2) can be made from standard grade magnetic iron ore products by cationic silica flotation. Continuous tests were run using various flowsheet arrangements, whereby (1) super and standard grade products were made simultaneously or (2) only a superconcentrate was produced. After a caustic scrub and desliming pretreatment, the silica in a magnetic taconite concentrate was reduced to 1.8 percent sio2 by amine flotation. Approximately 75 percent of the iron was recovered in the single flotation stage, and by additional beneficiation 95 percent of the total iron was ultimately recovered.
