| Summary: | The purpose of this research is to preliminarily study the hornblende syenite processing. The study includes characterization,separation and evaluation. Characterization has been carried out using thin section, X-ray diffraction, X-ray fluorescenceand electrokinetic measurement. A variety of techniques such as magnetic separation, froth flotation and combinationof these techniques were used to separate feldspar from syenite. Evaluation of the separations has been done using data fromyield of feldspar, X-ray fluorescence and cone firing test. The feldspar yield was used to evaluate the process efficiency.Besides chemical analysis, cone shrinkage, fired color and degree of vitrification were used to monitor the quality of therecovered feldspars. The feldspars were furthermore compared to the standard feldspar samples obtained from a ceramicmanufacturer. Finally, the processed feldspars were graded for using in various kinds of ceramics.
