An overview of the beneficiation of iron ores via

Flotation is the most effective solution, both technologically and economically, when upgrading iron concentrates. Research regarding iron ore flotation began in 1931, demonstrating that reverse cationic flotation is a very efficient method for beneficiating oxidised iron ores. This method can also be applied to reduce the silica content in magnetite concentrates obtained using wet low-intensity magnetic separation. Several studies describing the processing of iron ores via reverse

Iron ore slimes flotation ScienceDirect

01/10/2010 Vieira (2009) developed a process for the concentration of tailings from the mechanical machines flotation circuit of a large iron ore concentrator in Brazil, consisting of a mixed circuit, wet high intensity magnetic separation (WHIMS) followed by cationic reverse flotation. The rougher WHIMS stage yielded an iron pre-concentrate (34% Fe) at recovery level of 80%. The cleaning flotation

Froth Flotation of Iron Ores sapub

02/01/2012 Although the reverse cationic flotation route has become the most popular flotation route in iron ore industry, the direct flotation of iron oxides still appears desirable for some low grade iron ores that contain a vast amount of quartz. For example, at Republic Mine, Michigan, U.S.A., a hematite ore is upgraded from 36.5% Fe to 65.4% Fe with a Fe recovery of 82.5% using the direct flotation

Iron ore slimes flotation ScienceDirect

It was observed that a reverse cationic column flotation process, using high depressant dosage, was selective, yielding high grade concentrates with low impurity content at high levels of iron recovery, approximately 60% mass recovery and 80% metallic recovery in the flotation stage. Excellent valuable product grade (less than 1% silica) and reject product grade (approximately 12% iron) were achieved,

01/02/2005 Desliming prior to the reverse cationic flotation of iron ores was introduced with the UTY 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.

Oxide and Reverse Flotation SGS

In reverse flotation, proper reagents induce the pay minerals to become hydrophobic (water repelling) and the waste minerals to become hydrophilic (water attracting). Aeration is added through spargers at the bottom of the flotation cell. The bubbles attract and then float the waste minerals, leaving the pay minerals in the underflow. SGS has extensive experience conducting reverse flotation

The Characteristics of Iron Ore Slimes and Their

The flotation has been successfully applied to process the iron ore for the particle size (Ps) from 10 µm up to 150 µm. The presence of the slimes (Ps < 10 µm) is harmful on the reverse flotation of quartz, so they are usually prior removed by hydrocyclones. The main effects of the presence of slimes on the flotation are related to the increase on reagents consumption, the froth stability, and decrease on the

Separation of silica from bauxite via froth

01/03/2009 This paper reports an innovative development: concentrating gibbsite via reverse froth flotation in order to obtain a metallurgical-grade bauxite concentrate. Tailings from an industrial plant have undergone attrition scrubbing and desliming; the quartz silica contained in the tailings has undergone flotation. Starch was used as a depressant, and ether-amine as the cationic collector.
