US4908125A Froth flotation process for the recovery of

The invention is a collector composition for a flotation process containing a primary or secondary amine or amine salt and at least one of xanthates, dithiophosphates, mercaptobenzothiazoles, xanthogen formate and thioaocarbamate and a flotation process which utilizes the collector composition.

Froth Flotation Definition of Froth Flotation by Merriam

Froth flotation definition is - flotation in which air bubbles are introduced into a mixture of finely divided ore or other material with water and a chemical that aids attachment of the bubbles to the particles of the desired material and its recovery as a froth.

Froth flotation process and its application

The paper is about the froth flotation process and its application. It is a metallurgical process for the extraction of metals in a pure state from their ores: especially for sulfide ores. Froth flotation is one of the steps which is generally ... recovery efficiencies. 3.1. Collectors In a flotation system the surfactant reagents which are

Froth flotation process American Cyanamid Company

A process for the recovery of mineral values by froth flotation in an aqueous medium employing a novel frother. Frothers prepared by Michael addition between alpha, beta-unsaturated ethylenic compounds and either alcohols, amines or mercaptans or by the condensation of HCN, aldehydes/ketones with either alcoholics, amines or mercaptans have been found to be effective in the froth flotation ...

Grade recovery modelling and optimization of the froth

Dec 10, 2016 The corresponding experimental efficient or Pareto optimal combinations x* of the levels of the process variables are: pH = 2, dosage of collector = 500 g.t − 1 and flotation time of 12 min, which produces a concentrate with Li content of 1.96% and a Li recovery of 91.51%, and pH = 2, dosage of collector = 200 g.t − 1 and flotation time of ...

PDF Kinetics of flotation. Order of process rate

Froth flotation is a selective separation process, which is affected by many factors re lated to the floated mineral such as grade, degree of liberation, surface properties and many operating ...

Coarse PartiCle Flotation

PARTICLE FLOTATION Developed in 1999 and later patented in 2002, Eriez was the first in fluidized-bed flotation. This coarse particle recovery system has the ability to capture particles up to and exceeding 2 mm. Having reshaped the industrial minerals market, the HydroFloat is now being applied to the sulphide and base metal markets

Froth flotation definition of Froth flotation and

May 02, 2004 Froth flotation is one of the processes used to recover recycled paper.In the paper industry this step is called deinking or just flotation. The target is to release and remove the hydrophobic contaminants from the recycled paper. The contaminants are mostly printing ink and stickies.Normally the setup is a two stage system with 3,4 or 5 flotation cells in series.

Froth floatation Article about Froth floatation by The

Froth floatation of coal has been extensively studied and found to be feasible in enhancing the quality of coal by removal of unwanted minerals such as pyrite which is easily separated. A Denver DR floatation machine was used to perform froth floatation. This is an example of a typical froth floatation unit used in the mining industry.

Definition Of Recovery In Froth Flotation Process

froth flotation definition of froth flotation in the Free Online ... A process for recovery of particles of ore or other material, in which the particles adhere to bubbles and can be removed as part of the froth. McGraw-Hill... Read more

An evaluation of different models of water recovery in

Jul 01, 2006 Froth recovery is expressed as an exponential function of the mean froth residence time: (10) R f = e-β τ f where R f, froth recovery; β, constant, related to the froth characteristics. The overall recovery of the water is a result of the recovery of the water from the pulp phase to the froth phase and the recovery of the water from the froth phase to the concentrate.
