Ion precipitation flotation technology was demonstrated to be an efficient method for the separation of valuable metals from low-concentration solution. However, the selective separation of three metals from mixing solution is a great challenge, and highly selective reagents are the key to polymetal …
The growing demand for high-quality batteries has promoted frequent upgrading of Lithium-Ion Batteries (LIBs), resulting in a large number of spent LIBs entering into the waste stream. Grinding flotation may be a promising physical recycling method to help dispose of this waste. This study provides theoretical support for this technology by …
Ion flotation by F. Sebba, 1962, Elsevier Pub. Co. edition, in English
Ion flotation is said to be a highly efficient method for purification of aqueous streams from metal ions when their concentration in the range between 10 5 to 10 3 mol dm 3 [18]. The precipitate flotation differs from ion flotation by means of a different process mechanism. In the precipitate flotation, the feed solution is a suspension ...
In the original studies, ion flotation was mostly used for pre-concentrating precious metals from dilute solutions. To date, the ion flotation method has also been applied for wastewater and water treatment, 10–12 recovery of precious metals, 13,14 pre-concentrating of rare earth elements, 15,16 and selective separation of multicomponent …
Froth flotation of ores has been the only separation by flotation process widely used on an industrial scale (2), but recently flotation is applied very often in the environmental technology, especially for the separation of oily constituents from petroleum refineries (3). Ion flotation was introduced by Sebba at first (4), where the basic ...
An aryl-substituted aromatic acid ionic liquid (M-X) was synthesized through hexadecyl trimethyl ammonium bromide and sodium salicylate, and it was employed as a flotation collector for the separation of quartz from magnetite. Laboratory flotation studies of magnetite and quartz were conducted using the M-X and dodecylamine (DDA) as …
Ion flotation is an efficient method to remove or recovery of heavy metals, rare and precious metal ions, and organic pollutants from aqueous solution. The added surfactants served as collectors ...
In addition, the ionic radius is an essential factor influencing the ion-exchange in mineral surface lattices. DEMIR et al [26] studied the flotation separation of potassium feldspar and sodium feldspar, elaborating that Ca2+ can replace Na+ in the crystal lattice of Na-feldspar, while Ba2+ can replace K+ in the crystal lattice of K-feldspar.
The ion flotation method has been applied for wastewater and water treatment, recovery of precious and platinum group metals, preconcentrating of rare …
Ion flotation is a separation method that involves the adsorption of collector-ion complexes onto a liquid–gas interface. The collector ions tend to adsorb onto the surface of bubbles (Hoseinian et al., 2018a, Hoseinian et al., 2020c). The heavy metal ions removal primarily relies on the adsorption of product formed from the interaction ...

Ion flotation is a separation technology for recovering ions from dilute aqueous solutions. All ion flotation processes known so far make use of ionic ing agents (surfactants) to selectively extract ions of opposite charge by electrostatic interactions. Recently, it was shown that nanometric-sized ions (nano-ions) with low …
The ion flotation allows for the operate of the flotation cell with values of Jg equal to 1.0 cm/s. The detriment of the ionic flotation occurs when exclusively concentration combinations of dithiophosphate …
Ion flotation is a practical method that can be used to remove various metal ions from solutions.

Ion flotation was carried out in an XFG type flotation machine (Wuhan Exploration Machinery Plant, China) with a 50 mL flotation cell with a stirring speed at 1500 r/min. First, 40 mL of deionized water was added to the flotation cell. Next, a pH regulator was added and stirred for 2 min, and then, the metal ion solution was added and stirred ...
Ion flotation 1261 The Effect of Collector Concentration Galvin et al. [12] coined the phrase, ultimate recovery curve, to denote the relationship between the maximum possible recovery of a species and the concentration of the collector used. The ultimate recovery curve, equivalent to an ideal separation curve, provides a sound basis …
Ion flotation is a separation technology for recovering and removing metal ions from dilute aqueous solutions. In this process, an ionic collector is utilized to …
Simulating the Effect of Water Recirculation on Flotation ... Froth flotation is a multifaceted complex process which is water intensive. The use of recycled water as an alternative source of water to meet water demands of the process may introduce deleterious inorganic ions that affect the mineral surface, pulp chemistry, and reagent action, hence the need …

Ion flotation is the best method for removal of heavy metals from wastewaters. A recovery of Zn 2 + of more than 92% and a recovery of 88% Ni 2 + were achieved. Recovery increases by increasing agitating speed, water recovery and flotation time. Zn 2 + preferential removal is proportioned to ionic radius.
