Abstract

• lowest expansion coefficient of all metals. The quality and the costs of producing the metal greatly depends on the efficiency of the concentrating steps performed at the rather limited number of mining sites. In this work, the tungsten (W) and tin (Sn) were produced in wolframite ore from Kanbouk mine by calcinations process and their structural properties were analyzed by using X-ray diffraction method. The elemental analysis was done by Energy Dispersive X-rays Fluorescence (EDXRF) method. The electric and magnetic properties of these samples were also observed PERMAGRAPH L and LCR meter.
