  • Extraction of Chromium from Chromite Ore

    Armac C, a primary coco amine acetate, used as a collector and H2SO4 as a modifier yielded tailings with the lowest grade, 2.7 pct Cr2O3. Rougher concentrate grades were as high as 30 pct. Flotation tests to concentrate chromite in the slimes from the pilot plant gravity circuit were successful on the Seiad Creek and Broken Ladder samples.
