  • Froth Flotation of Iron Ores sapub

    2012-1-2 · With the depleting reserves of high-grade iron ore in the world, froth flotation has become increasingly important to process intermediate- and low-grade iron ore in an attempt to meet the rapidly growing demand on the international market. In over half a century’s practice in the iron ore industry, froth flotation has been established as an efficient method to remove impurities from iron ore.

  • Reverse anionic flotation of quartz from Muro iron ore

    Abstract. The recovery of iron from low-grade (31.6% Fe) Muro iron ore was investigated using reverse anionic flotation of quartz. Tests were performed to investigate the effect of pH, the effects of using distilled vs. tap water as the flotation medium and the effects of using cassava starch vs. dextrin for the depression of iron minerals.
