Flotation Feldspar Selective

Aug 01 1990 Selective flotation of muscovite from a material containing muscovite 154 biotite 13 and siliceous gangue quartz and feldspar using a mixed collector system of sodium oleate and dodecylamine acetate has been described Muscovite is found to float in preference to biotite when the pulp is initially conditioned with oleate followed by amine at basic pH values

regulators led to a reasonably selective feldspar flotation using the following procedure No frother was added and the collector dosages were optimised at Armoflote 820 1500gt with HF ca 1000gt and Armoflote 543 1800gt with H2SO4 ca 2000gt The addition of either HF or H2SO4 as pH regulators

Laboratory flotation tests using Naoleate and metal salts were also carried out to separate feldspar from quartz Flotation tests verified that there was a selective oleate adsorption to the K

ABSTRACT In order to develop the HFfree flotation reagent system the main objective of this investigation was to study the possibility of separation of quartz from feldspar using nonionic surfactants as the collector The nonionic surfactants

Selective Flotation Separation of Feldspar in Non Fluoride In the conventional flotation separation of feldsparquartz hydrofluoric acid is used to suppress quartz and activate feldspar and a long chain amine salt acetate or chloride is used as a collector The bulk of amine collectors used in current feldspar operations are applied as the

Abstract Flotation experiments performed on a quartzfeldspar mixture demonstrate that quartz can be floated selectively from feldspars in diluted solutions of hydrofluoric acid HF simply by the aid of a frother High grades and good recoveries were obtained for both quartz and feldspars A feldspar concentrate of 999 at a recovery of 956 was produced

In order to develop the HFfree flotation reagent system the main objective of this investigation was to study the possibility of separation of quartz from feldspar using nonionic surfactants as the collector The nonionic surfactants used were polyoxyethyl cethyl ether PECE and polyethylene glycol monocethyl ether PGME The flotation behaviour of quartz and microcline with

Previously a selective flotation separation of feldspar in the presence of HF was proposed by Fuerstenau et al in an acidic environment pH 21It was suggested that the HF method can achieve a good separation of feldspar and quartz with a high grade of feldspar and a highquality quartz However there is a large amount of chemical activator HF or NaF in the flotation system as

The reagent schemes are tested in benchscale flotation for the separation of albite from Greek Stefania feldspar ore The single mineral flotation tests showed the feasibility of selective albite flotation from quartz at around pH 2 using a mixture of cationic diamine and anionic sulfonate collectors or a combined cationicanionic collector of

Fatty acids particularly oleic acid are extensively used with reasonable success in the flotation of colored minerals from feldspar ores In this study potassium oleate oleoyl sarcosine and hydroxamate were used to float colored impurities both before and after magnetic separation

NaFeldspar KFeldspar Flotation Sand Separation Effect of pH T R Boulos et al 436 1 Introduction Feldspars are indispensable raw materials for many industries such as ceramics glass and fillers for plastics production Considerable reserves of feldspar varieties are found in the Eastern Desert of Egypt most of which Get Price

Dec 25 2018 0183 32 Abstract Flotation is the only technique that enables the selective separation of Na and K feldspar minerals from each other In this study the flotation separation of Nafeldspar

The best results were achieved with a combination of highintensity wet magnetic separation and flotation A feldspar concentrate containing 1628 Al2O3 1075 K2O284 Na2O6997 SiO2 and 0

Quartz Flotation Feldspar The flotation process is mainly to remove the nonmagnetic associated impurities in quartz sand such as feldspar mica The quartz sand flotation process mainly includes fluorine flotation and fluorinefree flotation process Selective Flotation Of Quartz And Feldspar Using Nonionic Study On Flotation Mechanism

Selective flotation of albite is accomplished from a natural feldspar material with tallow diaminedioleate collector at pH 2 using sulfuric acid only when the feed is deslimed prior to the bench

Even the separation of Nafeldspar from Kfeldspar is possible by flotation using monovalent salts Demir et al 2001 and Dogu and Arol 2004 found that it was possible to separate the dark

Flotation reagents refer to the agent that used in mineral flotation process which can adjust the flotation behavior of minerals thus achieving a good effect of mineral separationCurrently using flotation reagents is the most flexible effective and convenient method of controlling flotation processThe commonly used flotation reagents can be mainly divided into three types according to

May 02 2016 They revealed that Aero 3030C was more selective and preferred in feldspar and micas mineral flotation The present paper aimed to reduce the iron contents of Wadi Zirib feldspar ore and also to obtain an optimal commercial grade of feldspar
