Froth Flotation of Iron Ores sapub

2017-12-01· 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.

Reagents in iron ores flotation ScienceDirect

Desliming prior to the reverse cationic flotation of iron ores was introduced with the Uliming process (Clemmer, 1947).An adequate degree of dispersion of the particles in the pulp is a requisite for efficient desliming. A simple and inexpensive way of reaching a high dispersion degree is raising the pH with the use of large amounts of NaOH, increasing the electrostatic repulsion among the particles.

2020-05-07· Froth flotation is an important concentration process. This process can be used to separate any two different particles and operated by the surface chemistry of the particles. In flotation, bubbles are introduced into a pulp and the bubbles rise through the pulp. In the process, hydrophobic particles become bound to the surface of the bubbles.
