Effect of magnesium ion on sylvite flotation: An ...

In this work, the ions hydration insights into the effects of Mg 2+ on KCl flotation were investigated. The flotation tests show that the recovery of KCl was sharply decreased with addition of Mg 2+.The radial distribution function of water molecules indicates that Mg 2+ has strong hydration ability. Molecular Dynamic simulation results show that the hydration of Mg 2+ will significantly ...

ion flotation studied - gielguorde.nl

Ion flotation was elsewhere carried out to investigate the effective factors and kinetics of Zn(II) ion removal from wastewater . The optimum conditions were determined at first by experiments that were conducted in a Hallimond tube. The same group also studied ion flotation of nickel ions . This removal was evaluated based on various ...

Ion flotation—its potential for hydrometallurgical ...

1. Introduction. Ion flotation, first described by Sebba, 1959, Sebba, 1962, is a relatively novel separation technology for recovering and removing metal ions from dilute aqueous solutions Bernasconi et al., 1988, Jdid and Blazy, 1990, Ke, 1992, Matis and Mavros, 1991, Tessele et al., 1998.In this process, an ionic surface active reagent (collector) is added to the solution to be treated, and ...

An overview on the surfactants used in ion flotation ...

The surfactants used in ion flotation are therefore reviewed in the paper. Basically, the review focused on the development of the surfactants and their action mechanism with the ions to be separated, intending to provide ideas and inspirations to spark rapid development of the surfactants for the ion flotation of various inorganic and organic anions and cation.

(PDF) A Review of the Flotation of Copper Minerals

The concentrat ion of oxidise d copper minerals b y flotation has been exte nsively studied [7; 8]. It has been applied in Central Africa, especially Congo [9 ; 10 ; 11] .

ION FLOTATION - index-of.co.uk

Ion Flotation De\nition Ion Sotation, developed by Sebba, is a surface-inactive separation method that involves the removal of ions or molecules (colligend) from aqueous solu-tion by adding surfactant, that is adsorbed onto the surface of rising bubbles. The surfactant}colligend product (sublat) may be formed in bulk solution or 3180 III/ION ...

Ion Flotation - a metal recovery technique - …

Ion flotation is very useful for treating aqueous leachates from which the majority of the metals of importance has been removed yielding a dilute aqueous solution in which metals of great value still persist, and as water is the solvent often used for the leaching process that makes ideal conditions for ion flotation.

Ion foam flotation of neodymium: From speciation …

Ion foam flotation of neodymium (Nd 3+) was studied using a pH-sensitive surfactant, the nonaoxyethylene oleylether carboxilic acid, which has the peculiarity of remaining water soluble in the presence of multivalent cations.The flotation efficiency factors were determined as a function of pH and for two different (surfactant/Nd) molar ratios, equimolar (1/1) or stoichiometric (3/1).

Evaluation of ion separation coefficients by foam ...

Separation of metal cations of different charges, Na +, Li +, Ca 2+, Sr 2+, Cu 2+, Nd 3+ and Eu 3+ was investigated through ion foam flotation using a pH sensitive surfactant, nonaoxyethylene oleyl ether carboxylic acid. We propose here a method to evaluate ion selectivity coefficients using mass and volume balances.

Activation Mechanism of Lead(II) to Ilmenite …

In this study, salicylhydroxamic acid (SHA), which exhibits superior flotation performance to conventional collector benzohydroxamic acid (BHA), was first introduced in ilmenite flotation. The addition of lead(II) can significantly increase the recovery of ilmenite using SHA as collector. Thus, the adsorption mechanism of SHA on lead(II)-activated ilmenite surface was systematically studied ...

Iron removal by precipitate flotation - SciELO

The removal of Fe 3+ ions by flotation with sodium dodecyl sulphate (SDS) as collector was studied. The process was shown to be very efficient. Removal of 99.9% of the Fe 3+ contained in the original solution was obtained.

A new kinetic model for Ni(II) ion flotation based …

The Ni(II) ion flotation kinetics with sodium dodecylsulfate as collector was studied with the aim of developing new models to predict the flotation rate constant (k) of Ni(II) ions and water removal during the process of Ni(II) ion flotation.

Dissolved-Air Flotation of Metal Ions

DISSOLVED-AIR FLOTATION OF METAL IONS 1747 stoichiometric amount required. This seems to contradict previous results, where a 30% excess of sodium sulfide was found to be adequate (If), but a possible explanation can be traced to froth flotation (14) where sodium sulfide constitutes a depressing agent for sulfide ores.

Role of Water Structure-Making/Breaking Ions in the ...

bilities of the ite, which has never been studied in the literature, was ions in iron ore flotation pulp are usually ig-nored when discussingthe performance of iron ore flotation . The concept of “water structure breakers” and “water structure makers” was first introduced by Gurney, and

(PDF) Removal of Copper from Waters by Ion …

Under the studied conditions, ion and sorptive flotation were found to be effective methods for copper removal with almost 100% Cu removal achieved, while the precipitation method failed.

Solvent sublation and ion flotation in aqueous salt ...

25-3-2015 · The recovery of cerium and yttrium ions in solvent sublation and ion flotation processes was studied. The dependences of the distribution coefficients of cerium and yttrium dodecyl sulfates on pH of the equilibrium aqueous phase in the above processes were determined. Conditions for possible separation of cerium(III) and yttrium(III) ions in the adsorptive bubble recovery methods under ...
