Reverse anionic flotation of quartz from Muro iron ore

Nov 01, 1995· 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.

Assessment of iron ore mineral wastes for sulfate removal

From the predicted model, maximum sulfate adsorption onto metasomatite and quartz-albitophire was 31.07 and 20.27 mg g −1, respectively. This adsorption rate indicates that the seemingly worthless iron ore mineral waste can be useful to eliminate one of the most hazardous environmental pollutants.

Magnetic and flotation studies of banded hematite

Dec 16, 2010· To identify and establish beneficiation techniques for banded hematite quartzite (BHQ) iron ore, a comprehensive research on BHQ ore treatment was carried out. The BHQ ore was assayed as 38.9wt% Fe, 42.5wt% SiO2, and 1.0wt% Al2O3. In this ore, hematite and quartz are present as the major mineral phases where goethite, martite, and magnetite are present in small amounts.

Effectiveness Of Gravity Concentration For The

The rate of reduction of both iron ore and quartz varies (Figures 1 to 3). Quartz dissipates easily, breaking down to fines with little applied stress. Though the hardness value of quartz (i.e. 7 on the Mohr’s scale) is a bit higher than the iron ore (Hematite (5.5-6.5), Magnetite (5.5-6), it is far more brittle than iron ore (Gribble, 1988).
