Selective Leaching Trace Elements from Bauxite Residue (Red Mud) without and with Adding Solid NH<sub>4</sub>Cl Using Microwave Heating

Bauxite residue (red mud), which is an industrial byproduct, contains valuable trace elements. Solid NH<sub>4</sub>Cl was used as a chlorinating agent during the microwave heating of red mud to convert trace elements into soluble metal chloride. Red mud was heated using microwave ovens u...
