Disc Magnetic Separator Applied to the Extraction of Magnetite in Bauxite Residuel reasons. Iron oxides, mainly goethite and hematite, are major constituents of bauxite residue that also have a potential economic value. Many attempts have been reported in the literature, of reducing these species to magnetic iron oxides, such as magnetite, followed by its recovery using magnetic

Comprehensive Utilization of Red Mud Through the Recovery of Valuable Metals and Reuse of the Residuidue is proposed. In this study, inductively coupled plasma atomic emission spectroscopy, X-ray fluorescence, X-ray powder diffraction, and vibrating sample magnetometer were used to characterize the process. The process includes sintering, alkaline leaching to recover Na and Al, and removal of lead

Vadim Lipin,Ekaterina Sofronovand Skeith III had suggested a completely different approach towards achieving FHE. They showed that the . operator can be realized in some . groups; consequently, homomorphically encrypting the elements of the group will yield an FHE scheme, without ciphertext noise to be bootstrapped. However, no o
