Abstract. The recovery of iron from lowgrade 31.6 Fe Muro iron ore was investigated using reverse anionic flotation of quart. 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.
