Microwave-Absorbing Characteristics and XRD Characterization of Magnetic Separation Products of Reductive Products of Ilmenite Concentrate

Abstract

Abstract:The microwave absorbing characteristics of magnetic separation products (magnetic and non-magnetic) of reductive products of ilmenite concentrate were measured by the method of microwave cavity perturbation and the magnetic separation products were characterized by X-Ray Diffraction (XRD). It was demonstrated that metallic iron was a strong microwave absorbing material, while TiO 2 was a weak microwave absorbing material. The decrease of a strong microwave absorbing material and an increase of weak microwave absorbing material resulted in the great decrease of microwave absorbing characteristics of magnetic products by using a current intensity from 2.5 to 3.0 A. FeTi 2 O 5 was a strong microwave absorbing material, the increasing content would lead to the significant increase of the microwave absorbing characteristics of non-magnetic products by using a current intensity from 2.0 to 4.0 A. The conclusions could help us to optimize the ilmenite concentrate processing by microwaves and microwave cavity design.
