· 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).
· In order to improve the purity or the whiteness of feldspar, flotation [3,4,5] and magnetic separation are typically used to remove associated minerals (such as quartz, and dark-colored minerals rich in iron) from feldspar [6,7,8]. Traditionally, there are two main
Potassium feldspar mining equipment mainly include jaw crusher, ball mill, desliming bucket, hydrocyclone, strong and week magnetic separator, flotation cell, etc. the main process is curshing-milling-magnetic-flotation, etc. 1. Crushing: firstly, use the jaw 3.

In this study, recovery of feldspar from trachyte by flotation was studied. A feldspar concentrate containing 5.72% K2O, 5.33% Na2O, 0.321% Fe2O3 and 0.080% TiO2 was obtained from a feed ...
· Feldspars are used as a fluxing agent in ceramics and glass production. However, the presence of iron-bearing minerals reduces whiteness of the ceramics. The objective of this work was to decrease the Fe 2 O 3 content of a foyaite to <1% by flotation and magnetic separation, individually or combined, to make the sample suitable for white ceramics manufacture.

· After magnetic separation, 450 g/t of mixed collector MSD and 3000 g/t of regulator H 2 SO 4 are added to the pulp slurry for feldspar roughing flotation. For every flotation procedure, the final product of concentrates and tailings were filtered, dried, weighed and analyzed for Li 2 O.
· Traditionally, magnetic separation has only been introduced into the processing flow sheet of a feldspar operation at the dry stage, late in the process. Flotation is used to remove most other contaminants, explains Paul Fears, Marketing Director, of Eriez Magnetics ...
minutes. Magnetic separation is used as a backup process to remove any iron minerals present. Following the drying process, dry grinding is sometimes performed to reduce the feldspar to less than 74 µm (200 mesh) for use in ceramics, paints, and tiles

1. A froth flotation process for separating feldspar from quartz-feldspar sands ore consisting essentially of the steps of subdividing said ore to produce at least a fraction having a particle size less than about 1 mm, collecting said fraction and washing the same with water to effect desliming, introducing the washed fraction at a solid ...
The combined magnetic separation / froth flotation route produced feldspar concentrates from the granite fines with Fe203 contents approaching the specifications of glass-grade feldspar. Although Fez03 contents of <0.1 % are generally quoted for glass-grade material, levels as high
Generally, in the flotation process performed by using a reagent of Aero801 and Aero825 mixture in natural pH medium, both Fe 2 O 3 and TiO 2 can be removed at a rate of up to 90%, but magnetic separator can only remove Fe 2 O 3 mineral. 1. Introduction
An improved process for separating feldspars from feldspathic ores by means of froth flotation wherein a combination of a higher aliphatic amine salt and a higher aliphatic or aromatic sulfonate is used as a flotation reagent, eliminating the necessity for activation with ...
