Production of High Grade Iron Ore Concentrates Using Flota…

Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process. This article was most recently revised and updated by Chelsey Parrott-Sheffer, Research Editor.

accounted for a increase in the content of iron and a con- siderable reduction in the SiO2 content in the iron con- centrate, while the recovery of the mass and of Fe fell. It is important to add a depressant agent to the iron mi- nerals in the iron ore reverse flotation. In this work, corn starch and CMC (carboxymethylcellulose) were used.

Jan 30, 2015· For example, in poly-metal ores such as Pb-Zn-Cu, floatation allows separate extraction of Pb, Cu and Zn. The process of separation of mineral includes three important mechanisms : 1. TRUE FLOTATION, i.e., selective attachment to air bubbles. 2. ENTRAINMENT in the water which passes through the froth. 3.

Flotation is used to reduce the content of impurities in low-grade iron ores. Iron ores can be concentrated either by direct anionic flotation of iron oxides or reverse cationic flotation of silica, however reverse cationic flotation remains the most popular flotation route used in the iron industry.

Recovery of Iron Ore Tailings byColumn Flotation

Iron ore - Wikipedia. Queiroz (2003) verified that, for certain itabirite ore types, the use of attrition allows the increase of the mass recovery to the slimes and flotation concentrate fractions and the decrease of iron grade in the flotation tailings, iron grade in the slimes and SiO 2, Al 2 O 3 and P grades in the concentrate, resulting in higher figures for Gaudin's selectivity index.
