This article presents a study of the chemical–mineralogical composition, granulometric distribution, and physicochemicalproperties of feldspar raw material obtained from the Sultan Uvays deposit located in the Republic of Karakalpakstan, Lower AmuDarya region.According to the results of X-ray diffraction analysis, the sample predominantly consists of microcline (60–65%), albite (21–25%),quartz (7–10%), and calcite (2–3%).To obtain a concentrate suitable for the glass industry, a four-stage dry beneficiation technology has been developed and experimentallytested. This process includes magnetic separation (H = 80–1300 kA/m) and electrostatic separation methods.The beneficiation results demonstrate that the SiO₂ content in the feldspar fraction increased from 68.44 wt.% to 74.60 wt.%, while thetotal iron content (Fe₂O₃ + FeO) decreased from 0.29 wt.% to 0.01 wt.%.The obtained results confirm that feldspar from the Sultan Uvays deposit meets the requirements of GOST 22557-2019 and can bewidely used as an independent raw material in the production of glass and enamel coatings
