Atrac 1563 Flotation Iron Ore

Since exact composition and chemical structure of Atrac 1563 were not specified by the supplier, dodecyloxyethoxyethoxyeth- oxyethyl maleate (Sigma-Aldrich) was used as a model flotation...

The properties of iron ore green pellets with varying additions of a surface-active flotation collector reagent (Atrac) were studied by small-scale balling.

Flotation of iron ore Over the past few decades, silica flotation processes have increased, a trend that will continue as more complex ores have to be mined and the steel industry requests higher-grade iron ore concentrates with lower levels of impurities. For more than 40 years, we have been developing flotation collectors for magnetite

In this work, the adsorption of three model collectors, viz., poly (ethylene glycol) monooleate (PEGMO), ethyl oleate, and maleic acid, as well as the commercial fatty-acid-type …

The results show that the entrainment rate depends on the reagent type and indicates that it is higher for MIBC (alcohol) than for Atrac 1563 (carboxylic acid). …

AkzoNobel is a leading global supplier of flotation reagents and collectors for industrial minerals and iron ore applications. It says it "has gained its leadership position by being at the forefront of the advanced colloid and surface chemistry upon which successful flotation depends – a position it has achieved with more than 40 years of research and development in …

The aim of this paper is to provide a well-detailed, well-referenced source for the current status of iron ore flotation, and thus provide a useful guide to its future development and to further ...

No frother was added to the flotation cell since Atrac 1563 has frothing properties itself. Once the air was opened, the concentrates were collected at 1, 3, 5, and 7 min. At the end of the flotation process (after 7 min), the respective samples and the remaining material reported to the tailings were collected in different containers.

3.1.2. Collectors in Direct Iron Ore Flotation Hematite, goethite and magnetite are the iron oxide minerals, which are separated from the gangue mineral by direct flotation. Iron ore flotation started with direct flotation of iron oxides using selected anionic collectors such as petroleum sulphonates, fatty acids and hydroxamates.

Flotation test results showed a significant increase in the flotation recovery (by 37%) and grade (more than 1%) of fine phosphate ore sample (d80: 37 µm) using NBs that generated in the presence ...

In this study, a fungal cellulase enzyme was applied to improve the selective separation of apatite from hematite during the reverse anionic flotation of a high-phosphorus iron ore. Bench-scale ...

the production of iron ore pellets. A method was developed to study the adsorption of the surfactant Atrac 1563 on synthetic hematite in situ by means of ATR - FTIR spectroscopy. The adsorption of Atrac 1563 on hematite at pH 8.5 was found to mostly occur via interactions between the polar ester and ethoxy groups of the surfactant and the hematite

The flotation of iron ore was first investigated in America starting in 1931 (Iwasaki 1983, 1999; Uwadiale 1992). Over time, several different flotation routes have been devised.
