Laterites are found in the tropics deposits as the residual soils and consists largely of aluminium and ferric hydroxides, with more or less free silica and other constituents, varying widely in composition and purity. The process of beneficiation may be defined as concentration or preparation for smelting iron ores that is facilitated by separating mineral aggregates into homogeneous materials. Hence, the heterogeneity of constituent minerals in laterites is the prerequisite of beneficiating laterites. The present paper deals with the experiments of beneficiating a lateritic ore from Phillipines. The constituent minerals such as goethite, hematite, maghemite, magnetite, ilmenite, chromite and pyrite have been identified under the microscope. The close examination of the characteristics of these minerals led us to develop a new process of beneficiating laterites, called "Roast-High Intensity-Thermomagnetic Separation." The description is given of the flowsheet for the treatment of laterites by means of the "R-H-T process." The results of separation are discussed in terms of chemical analyses, X-ray diffraction and electron-probe microanalyses.
