Abstract
The federal Bureau of Mines, as part of a program to insure future raw material needs for the iron and steel industry, undertook research to beneficiate the oxidized taconites from the Western Mesabi Range in Minnesota. The data presented were obtained by applying the Bureau-developed selective-flocculation/cationic- flotation process to the second of three oxidized taconite samples. These three samples are representative of an estimated 10 billion tons of ore analyzing 30 to 40 pct iron. The experimental work was performed in a 900-lb/hr pilot plant. Treating the ore sample (36.1 pct fe) with the Bureau's process produced commercially acceptable concentrates averaging 63.5 Fe and 4.3 pct sio2, with an average iron recovery of 84.6 pct.
