Feldspar Beneficiation & Flotation Process
Metallurgical ContentThe Feldspar Beneficiation & Flotation Process FlowsheetFeldspar Ore CrushingFeldspar Ore GrindingFiltering and Drying of Feldspar ConcentrateDesliming and Conditioning 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.

Table of ContentsConventional Feldspar Flotation Using HFThe Non-Hf Feldspar Flotation MethodProcess DescriptionExperimental Results Feldspathic deposits occur widely throughout the United States, but North Carolina, California, Connecticut and South Carolina accounted for over 80% of the total domestic feldspar output for the year 1973.
Beneficiation of feldspar ore for application in the ...
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.

Feldspar Mineral Processing | ArrMaz
Feldspar Mineral Processing. Feldspar ore is the main source of feldspar mineral concentrate or purified feldspar used in the manufacture of various grades of glass and ceramics including high-end ceramics and electronic-grade glass fibers.
Concentration of K-feldspar from a pegmatitic feldspar ore ...
Abundant reserves of Na-feldspar (albite) and K-feldspar (orthoclase or microcline) are found in granites, syenite, tracite and pegmatites. As both feldspar minerals have similar stone structure and physicochemical properties, their separation is challenging. Flotation is known to be the only technique to enable their separation.

present, the first flotation step may be bypassed. Sometimes the final flotation stage is omitted, leaving a feldspar-silica mixture (often referred to as sandspar), which is usually used in glassmaking. From the completed flotation process, the feldspar float concentrate is dewatered to 5 to 9 percent moisture.
Effects of Ultrasound on Desliming Prior to Feldspar Flotation
In this study, the effects of ultrasound on removal of impurities from raw feldspar were investigated by testing with a newly developed flotation cell with various frequency and power intensities prior to multistage feldspar flotation. Particularly, the quality of feldspar concentrates, the volume of removed slimes and the content of impurities were taken into account to reveal the impacts.
