Selective separation of Na- and K-feldspar from weathered granites by flotation in HF medium Ceramics – Silikáty 54 (1) 60-64 (2010) 63 concentration to determine the effect of amine on the selective separation of albite from orthoclase, seen in the Figure 5, the most efficient separation with high K2O
yields good results. Quartz in excess of 3 percent remained in only two of the seventeen samples studied. INrnooucrroN Flotation separation of feldspars from quartz was first accomplished in 1936 (Ladoo and Meyers, 1951, p. 216) and has been used commercial-ly for many years. For example, the feldspar plant at Kona, North Caro-
The feldspar minerals and quartz were separated from each other by flotation of feldspar minerals and depression of quartz minerals. Both feldspar and quartz in amine flotation and in the absence of HF need not be floated at pH less than 4. However, in the presence of HF feldspar is floated at pH 2–3 while quartz does not float.
for acidic minerals, were used in the flotation of feldspars in the thirties. In 1982, it was found that C 6-14 primary amine hydrochloride collectors were used for the flotation of feldspars in presence of HF or a mixture of HF and NaCl. The C 10-12 amine gave the best flotation results [7] [8]. The feldspar was activated whereas the quartz was

Quartz, feldspar, froth flotation, mica waste dump hydrochloric acid flotation process for separating feldspar from an improved process for the separation of feldspar i.E.Quartz sand, by means of froth flotation in a conventional froth flotation process, feldspar has .
flotation separation of feldspar from quartz. Feldspar Beneficiation Flotation Process Feldspar Beneficiation Flotation Process. Beneficiation by Flotation of feldspar is well established. It is a simple matter by flotation to remove the contaminating impurities and keep the alumina (Al2O3) content at 19% even on low grade feldspar ores.
Review of flotation of feldspar: Mineral Processing and . 2012-02-14 AbstractThis paper reviews the application of flotation for the separation of feldspar from the other minerals with which it naturally occurs (such as quartz, clay minerals, mica, ilmenite, rutile, anatase and magnetite) as ...
Froth flotation is the selected method for the separation of quartz and feldspar. In the conventional process, feldspar is floated from quartz by using hydrofluoric acid (HF) as activator for the feldspar and a cationic collector (amine) at pH 2–3 (O'Meara, 1939).
Jun 25, 2019· Quartz-feldspar flotation separation The trading flotation separation method of quartz-feldspar is the HF acid method. consider of the environment protection, most mineral workers prefer to free-fluorine acid method. Flotation separation of potash feldspar and albite
Jul 18, 2013· This paper reviews the application of flotation for the separation of feldspar from the other minerals with which it naturally occurs (such as quartz, clay minerals, mica, ilmenite, rutile, anatase and magnetite) as well as the separation of the individual feldspar minerals themselves.
Feldspar Flotation In Brazil. Feldspar quartz mica separation machine seperation of mica from feldspar quartz mica ground machinery for extraction, separation and processing for quartz,, this paper reviews the application of flotation for the separation of feldspar from the other quartzthis procedure results in feldspar.
Since the inception of the feldspar flotation process using hydrofluoric acid by O'Meara the process has achieved a great commercial success. In the conventional flotation separation of feldspar-quartz, hydrofluoric acid is used to suppress quartz and activate feldspar, and a long chain amine salt (acetate or chloride) is used as a collector.
In the present study, from experimental results, a new concept of possibility of flotation separation of quartz from feldspar is presented. The effect of the nonionic surfactant Brij 58 on the flotation behaviour of quartz and feldspar has been investigated. The effect of the surfactant adsorption at the solid-liquid interface was also studied.
With feldspar the entrained free quartz was first removed by additional selective flotation (without and with surface preparation) after which a combination of acid leach and magnetic separation ...
Apr 27, 2007· Primary monoamines have been long used and studied as flotation collectors for quartz. In the past several mechanisms have been proposed to explain the manner in which the amines adsorb onto and render the mineral hydrophobic and, thus, floatable.
Dec 06, 2012· Feldspar ore Beneficiation, Magnetic separation for quartz . Magnetic separation and froth flotation testwork was . The mineralogical studies showed that intergrown feldspar/quartz particles were practically absent in . Separation of quartz & feldspar .
This paper reviews the application of flotation for the separation of feldspar from the other minerals with which it naturally occurs (such as quartz, clay minerals, mica, ilmenite, rutile, anatase and magnetite) as well as the separation of the individual feldspar minerals themselves.
Flotation separation of quartz from feldspar 1233 EXPERIMENTAL RESULTS Potentiometric titrations were conducted with each of the minerals to determine their zero points of charge. The ZPC of quartz and feldspar (microcline) are at pH 2.0 and 1.0 respectively. These values are quite consistent with the other reported values [1].
new condition for separation of orthoclase from quartz by flotation. Washing and high intensity magnetic separation (12 Ampere) afford to reduce the iron-bearing impurities up to 0.09 % Fe^sub 2^O^sub 3^, and the flotation is the best way for the separation of K-feldspar from quartz by appropriate reagents for this purpose (HBr, amine).
