Potassium feldspar is one of the basic needs of glass, ceramic, electrical insulation and other industries. One of the challenging factors in feldspar processing industries is the presence of iron and silica in feldspar. In order to increase the quality of feldspar concentrate for use in related industries, flotation is one of the most common methods of reduce iron and silicon content in feldspar. Therefore, in this study, the ore was crushed for 15 minutes to reduce the particle size below 150 microns. Then the mineralogical and chemical composition of the crushed product were determined by conventional XRF and XRD methods. Based on the mineralogical and chemical composition of the crushed product, different flotation scenarios were designed to reduce the iron and silica content in feldspar were investigated. The amount of silica and iron in the samples used in this study were 73.31 and 0.31%, respectively. In the first stage, in order to reduce iron, reverse flotation experiments were performed. In reverse flotation experiments, using a combination of 800 g/ton of each of the two collectors Aero 801 and 845 with 100 g/ton of pine oil frother at a pH of 2.5-2.9, the iron content to a level of 0.11%, Decreased. Also, to reduce silica content up to 57.26%, 400 g/ton of fluoric acid detector with 200 g/ton methyl isobutyl carbinol (MIBC) frother was obtained at pH 2.8-3. Feldspar with this percentage of impurities is suitable for use in required industries such as ceramic and tile.
