The effects of partially replacing amine collectors by a commercial frother in a reverse cationic hematite flotation [PDF]

open access: yesHeliyon, 2021
Iron ore froth flotation has recently been used to obtain pure minerals due to the depletion of high-grade deposits. Amine collectors have often been used in cationic reverse iron ore flotation to achieve the separation with quartz impurities.

On the frother’s strength and its performance

open access: yesMinerals Engineering, 2021
Abstract It is a common rule that the strength of the frother is assessed by either its dynamic foamability index (DFI) or its critical coalescence concentration (CCC). The smaller the value of CCC the stronger the frother is. This general rule (CCC rule) however is superficial although being well accepted. Yet, there are critical questions about the

An increase in the Copper Recovery of the Sarcheshmeh Copper Complex through Reagent Modifications [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 2022
In the flotation of sulfide minerals, particularly in the separation between pyrite and chalcopyrite, adjustment of the pH and reagents dosages is very important.  Process auditing at the Sarcheshmeh copper complex showed that the pH in the rougher cells

Effect of Diesel Oil and Mixture of Alcohol-Glycol Ether on Colombian Ultrafine Coal Cleaning Using a Test-Rig Closed-Loop Flotation Column

open access: yesIngeniería e Investigación, 2021
A test-rig closed-loop flotation column was used to observe the effect of diesel oil (collector) and Flomin F-425 (frother) on mass yield and ash content for two Colombian coals: Caypa (northern zone) and Guachinte (southwestern zone).

Effects of Flotation Reagents on Flotation Kinetics of Aphanitic (Microcrystalline) Graphite

open access: yesSeparations, 2022
The flotation method is widely used for the preliminary beneficiation of aphanitic (microcrystalline) graphite. However, there is limited literature regarding the effects of flotation reagents on the flotation kinetics of aphanitic graphite.

Effect of frother concentration on bubble trailing vortex characteristics and particle entrainment in flotation

open access: yesMeitan kexue jishu, 2023
To investigate the effect of frother concentration on bubbles and their tail vortex zone characteristics in flotation is an important prerequisite for predicting the probability of particle coiling in the trailing vortex zone of flotation bubbles.

Classification of Flotation Frothers [PDF]

open access: yesMinerals, 2018
In this paper, a scheme of flotation frothers classification is presented. The scheme first indicates the physical system in which a frother is present and four of them i.e., pure state, aqueous solution, aqueous solution/gas system and aqueous solution/gas/solid system are distinguished.
