Effects of alumina in iron ore ResearchGate. These contaminants produce thick scaling in the DRI kilns and impede heat . The alumina to silica ratio in iron ore should be less than 1.5 and preferably below.
The Lower-grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities.
Abstract. 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.

Iron Ore Processing Plant Equipment For Pakistan Iron Ore Mining . Our iron ore processing plant is widely used in Pakistan iron ore mine such as flotation where waste material such as silica is separated from the iron particles.
The present target level for silica contamination in JMZ zinc concentrates is 0.3% SiO2. This work has shown that selective flocculation offers a potential method for cleaning flotation concentrates, particularly where low silica products are required.
Synthesis of Fine Silica Particles from Iron Ore Tailings . Fine silica particles were synthesized using sodium silicate from the iron ore tailings and ion exchange of ammonium sulfate at room temperature by water-in-oil (w/o) emulsion containing water, nonionic surfactant of Triton X-100, and cyclohexane.
The silica differential in the iron ore price is the discount buyers get according to silica content in the iron ore. The 1% silica differential for iron ore cargoes with 60% Fe to 63.5% Fe fell to a historical low of $0.25/dmt July 8, from $1.50/dmt on January 7, according to Platts data.
