Reagents in iron ores flotation ScienceDirect

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.

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, stone starch and CMC (carboxymethylcellulose) were used.

Flotation ore dressing Britannica

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.

Iron ore Wikipedia

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. The results, high-quality fine ore powders, are known as fines. Magnetite. Magnetite is magnetic, and hence easily separated from the gangue minerals and
