Effect of Ore Pulp Density and pH Value on Silica in Iron Ore

Iron ore flotation is an efficient method to remove impurities from iron ore. Some amount of silicon dioxide is found in the ore even after separation from the magnetic and hydraulic mechanism. The most widely used method of flotation is the reverse cationic flotation route. The low-grade iron ores contain high grades of silica and alumina.

material and is the worst of the three types and contains high alumina, silica and low iron. In the hard ore hand specimens banding are observed both megascopically and microscopically while in medium hard ores the laminations are vague due to intense leaching and presence of innumerable voids (Figs.1-3). The hard ores usually show massive texture.

Iron Ore Homestead

The typical magnetite iron ore concentrate has less than 0.1% phosphorus, 3-7% silica and less than 3% aluminum. The grain size of the magnetite and its degree of comingling with the silica groundmass determine the grind size to which the rock must be reduced to enable efficient magnetic separation to provide a high purity magnetite concentrate.

A Study on High-Grade Iron ore Beneficiation to Reduce

May 21, 2020· Iron ore pellets are largely characterized by inherent physical and chemical properties of the ore. Alumina and silica play important roles in determining the productivity of a Blast Furnace. On average, one percent increase in iron content improves productivity by 2% and reduces coke consumption by 1%. Therefore higher iron ore feed content to blast furnace is always preferred.
