The Use of Flotation and High-Intensity Magnetic Separation to Improve Feldspar Concentrate Quality
Abstract
The flotation process and magnetic separation are the most common methods for feldspar beneficiation containing approximately 0.4% Fe2O3 and 0.04% TiO2. A model MIH (13) 111-5 Induced Roll dry high-intensity magnetic separator was used in this investigation to produce high-quality feldspar concentrate, and investigate the effects of magnetic field strength and roll speed on reducing coloring minerals. The best results were obtained at a magnetic field intensity of 16600 Gauss and a roller speed of 24 rpm. A feldspar concentrate containing 0.16% Fe2O3, 0.01% TiO2 and 10.31% alkali minerals (K2O+Na2O) was obtained with a mass recovery of approximately 69.24%. As a result, the products that met the white glaze and ceramic requirements were produced.
