Froth flotation of iron ores AMERICAN CYANAMID CO

This invention relates to the beneficiation of iron ores by froth flotation. More particularly, the invention relates to a two-stage flotation process suitable for use on fines such as are found in the overflow from iron ore washer plants; in waste products from heavy media separation processes and on those ores which must be finely ground in order to unlock the iron minerals from the gangue.

US4732667A Process and composition for the froth

A process and composition are provided for the froth flotation beneficiation of iron minerals from iron ores containing silicate and phosphate minerals, comprising as collectors a combination of a primary amine and a nitrogen compound containing an anionic group selected from methylene carboxylic acid, ethylene phosphoric acid and methylene phosphonic acid.

Process for froth flotation of silicate containing iron

Nov 25, 1998 The present invention relates to a process for enriching an iron mineral from a silicate-containing iron ore by carrying out, at a pH of 8-11, a froth flotation in the presence of a depressing agent for the iron mineral and a collecting agent containing a combination of an ether monoamine and an ether polyamine, which contain an aliphatic hydrocarbon group having 6-22 carbon atoms in a weight ...

Froth Floation Hoffman amp Lamson Solutions

Froth flotation, also called ore flotation when used in mining applications, is a method for physically separating particles by having air bubbles that selectively adhere to specific surfaces. The particles with attached air bubbles are carried to the surface and removed. Froth flotation is one of the most widely used methods for ore beneficiation.

PDF Activation of high iron marmatite in froth flotation

It might suggest that it is the 2 2 CuNH3 and Cu NH3 2 that activated high-iron marma- Fig. 5. Flotation kinetics of the high-iron marmatite with ammoniacal copper(II) solution, copper sulfate and ammonium chloride as the tite particles in the froth flotation through their …

Pilot Scale Froth Flotation Studies To Upgrade Nigerian

pre-concentration of iron ore by gravity or magnetic methods. The flotation method commonly applied is the one based on cationic flotation of silica and silicates, that is, reverse flotation [5]. The reagents required for froth flotation are collectors, frothers and regulators, such as activators and depressants.

Common Iron Ore Extraction Processes

Nov 15, 2019 Froth flotation process is mainly adopted to the extraction of weak magnetic iron ore with fine particles, including positive flotation and reverse flotation process. Among them, the positive flotation process is suitable for the quartz hematite without easily floating gangue, while the reverse flotation process is suitable for the extraction ...

FlotationNet A hierarchical deep learning network for

Sep 20, 2020 In this froth flotation system, the main goal is to purify the iron from the original iron pulp, incidentally decreasing the silica purity as a by-product. By assigning a larger weight to ℒ = 2 (λ 2 = 0.7), we ensure that most losses in FlotationNet are from prediction errors of silica.

PDF Reagents in iron ores flotation

The role of reagents utilised in iron ores flotation is reviewed. Desliming and flotation stages should be performed at pH levels as low as possible to reduce the expenses with caustic soda.

Separation of wolframite ore by froth flotation using a

Sep 01, 2021 Froth flotation is a more efficient physical-chemical separation method for wolframite concentrate production, ... and the complexing ability and strength of metal ions such as calcium, manganese and iron on wolframite surface need to be improved [18,20]. Download : …

Froth Flotation Hazen Research

Froth flotation for separating discrete mineral particles from gangue was developed in the early 1900s and depends upon differences in the surface chemistry of the mineral species involved. We have studied not only the flotation of sulfides, gold ores, iron ores, coal, oil shale, and many other nonmetallics, but also soluble salts, oxides, and ...

Machine Learning based Quality Prediction in the Froth

Froth flotation is defined as “a flotation process in which the minerals floated gather in and on the surface of bubbles of air or gas driven into or generated in the liquid in some convenient manner” [10].Metal sulfide ore such as Zinc, Phosphate, Cobalt, Copper, and Iron

Froth Flotation an overview ScienceDirect Topics

Froth flotation will remain a key unit process for the treatment of iron ores for the decades to come with the overarching challenge best described as being the need to modify and improve existing procedures and processing conditions so as to maintain an acceptable iron grade-recovery response in the face of ores and feedstock that will be finer, more complex, lower in grade, more goethitic in nature, and …

Froth Flotation of Iron Ores CSIRO Publications

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. In this chapter, the industrial practice and fundamental research activities of iron ore flotation are reviewed. The latest innovations in iron ore flotation at major iron ore operations around
