Beneficiation of a feldspar ore for application in the ceramic industry At +500 µm, approximately 46% of the ore material, rich in quartz and with the lowest iron oxide content At 500/74 µm, approximately 27% of the ore, rich in feldspar (≈46%),with a mean total iron oxide content averaging 0.29%
The present invention provides a process for the separation of minerals by flotation in the presence of activators and suppressors. Activators are cation-active condensation products and suppressors are anion-active products of aminoplast formers, formaldehyde and amines, ammonium salts, acids or a sulphite, in combination with either an anion-active or cation-active tensides.
An anionic-cationic flotation of two Egyptian feldspar samples, representing Road Ashaab locality of the Eastern Desert of Egypt, was investigated on both laboratory and pilot plant scales. The pegmatites belong to the alkali feldspar granite type, mostly microcline and orthoclase, KAL Si3O8 coarse grained rocks. Quartz, as the main gangue mineral, occurs in two forms as either free grains or ...
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-
Feb 19, 2017· Iron oxide is the main contaminant of clay and silicate minerals used during the production of high quality ceramics. Its content has to be removed to generally less than 0.1% for achieving the required whiteness of 90% ISO or higher for clay and silicate materials. Oxalate has been used to dissolve iron oxide from various sources.

These reagent systems open up possibility for HF-free flotation separation of quartz from feldspar.Special importance is attached to the addition of suitable …
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. The bulk of amine collectors used in current feldspar operations are applied as the water-soluble acetates of the free-base amines. Get More
Quartz can be floated from feldspar in diluted HF solutions simply by the aid of frothers. • There is a high flotation separation selectivity between quartz and different types of feldspar. • A feldspar concentrate of 99.9% at a recovery of >95% was produced. • The results could be …

Zeolite veins without alteration envelopes cut all other vein types. Potassic alteration assemblages with pervasive biotite ± K-feldspar ± magnetite comprise the best developed and earliest alteration suite. It is most intense in proximal locations where quartz + K-feldspar veins locally compose upwards of 30 vol percent of the rock.

Jul 3, 2014 Most of the time a person wanting to clean quartz crystals is trying to remove brown "iron stains" or a white coating from the crystals. . a quartz providing that the air pressure is not to high and that the glass beads are relatively clean and do not contain to many sharp of broken glass or other hard impurities.
Of these, gneiss is a metamorphic rock type, which is characterized by dark and light colored minerals including feldspar and quartz. In this study, Augen-Gneiss rock was subjected to flotation tests to produce alkali (Na + Ca) feldspar and quartz concentrates by adapting different flotation conditions with/without hydrofluoric acid (HF).
Under these conditions, neither quartz nor feldspar will float unless activated. Following the flotation of mica, titanium and iron oxide minerals may be removed at the same pH using an anionic collector (e.g. a petroleum sulphonate) at a dose rate of about 0·5–2·0 kg t −1. Again, neither quartz nor feldspar will float unless activated.
2012). If desired, separation of feldspar from quartz can be provided after flotation of heavy minerals. Firstly, feldspar is activated by hydrofluoric acid, and then floated by amines at pH 2.5-3.5 (Gulsoy et al., 2004). Also, the non-HF process for flotation of feldspar was developed by using diamine acetate

Magnetic separation alone decreased the iron contents of the feed to a range between 0.10 and 0. 12 % iron oxides with an average yield greater than 85 %. Flotation with HF provided a feldspar recovery of 45-55 % with a concentrates assaying 17-17.35 % Al 2O 3. Iron contents were ...
Potassium feldspar and quartz are all silicate minerals with frame structure,and have the similar crystal structure and physicochemical properties. Therefore, flotation has become the main method to separate potassium feldspar from quartz. The separation of potassium feldspar from quartz with anion and cation mixed collector was studied in the paper.
