  • Froth Flotation of Iron Ores sapub

    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.(PDF) Reagents in iron ores flotation ResearchGate,The role of reagents utilised in iron ores flotation is reviewed. Desliming and flotation stages should be performed at pH levels as low as possible to reduce the expenses with caustic soda.

    Flotation circuits are often operated at a pH range of 7.5 to 11.5. The exact range at any given plant is optimized for the ore at that site. Lime is often used to raise the pH of the pulp and also reduce the flotation of iron pyrite. Particle Size. The particle size to which the ore is ground depends on the nature of the ore.CHAPTER-9 FROTH FLOTATION AND ITS APPLICATION TO,mechanical adjuncts of the flotation process.
