In this research, Effect of thermal treatment on beneficiation of low-grade laterite nickel by calcination-magnetic separation method was studied. In order to determine the components and elements of the sample, to recognize the main and minor minerals and their bond, and phase transformation caused by thermal treatment, Chemical analysis (XRF and ICP), microscopic studies and XRD analysis ...
The purpose of the present study is to investigate the boundary layer separation point in a magnetohydrodynamics diffuser. As an innovation, the Re value on the separation point is determined for the non-Newtonian fluid flow under the influence of the non-uniform magnetic field due to an electrical solenoid, in an empirical case. The governing equations include continuity and momentum are solve...
toluidine blue o (tbo) is a cationic dye which is extensively used in the industries. in the present paper a simple and efficient wet chemical method was introduced for removal of tbo from waste aqueous solution. magnetic multi-walled carbon nanotubes were synthesized using commercially available multi-wall carbon nanotubes and magnetic iron oxide nanoparticles which were examined for removal o...
Low-intensity magnetic separators are widely used in the research works and the industry. Advancement in the magnetic separation techniques has led to an expansion in the application of this method in different fields such as enrichment of magnetic mineral, wastewater treatment, and medicine transfer in the human body. In the mineral processing industry, the main application of wet magnetic sep...
In this research, a seawater desalination system has been studied and simulated by magnetic-electric method. The electric field is considered to ionize seawater and the magnetic field to isolate it. The equations of motion of water and salt particles are modeled by the Euler-Lagrangian method. Particularly important for the separation of micron diameter salts, the magnitude of the electric and ...
in this research, some more applicable ferrofluids are produced and their mechanical specifications are measured, experimentally. also, their treatments in the ventilated cavity geometry are assessed numerically. the magnetite nanoparticles are produced by a chemical combination of fe2+ and fe3+ with nh3. in order to solve the nanoparticles in the new mediums, a proper coating is added to them....
