Abstract | The present work represents research results of properties of monomineral fractions, extracted from red muds. Main fractions of a red mud are hematite, chamosite and calcite. These fractions were obtained by methods of beneficiation. Material composition and physical properties (signs) of monomineral fractions were defined such as specific magnetic susceptibility and a true density and also the contrast coefficient between separate fractions on each of physical signs was calculated. Maximum values of contrast coefficients 3.75 and 2.3 on a specific magnetic susceptibility respectively were received between hematite, calcite and chamosite. As first steps within a process flow sheet it enabled to predict a main and a cleaning high-gradient magnetic separation with the induction of the magnetic field 1.4-1.5 T, the values of which were obtained by studying dependence of a specific |
