The Beneficiation flowsheet shown with this study is particularly adapted to the concentration of tungsten ore in small tonnages. Tungsten minerals are generally in the friable class and therefore concentrating processes are hindered by the excess amount of fines produced in the crushing and grinding steps.

Tungsten, abbreviated as W on the periodic table, is a rare and valuable metal known for its exceptional physical and chemical properties. Tungsten ore refers to the natural rock or mineral containing tungsten in its compound form. Tungsten is commonly found in nature in the form of tungstates, such as scheelite (CaWO4) and …

Essentially, it is easy to obtain higher separation efficiencies when jigs are employed for the physical beneficiation of HMs, especially when there is a relatively high difference in the SG between the HM particles in the ore deposit. Also, good beneficiation may be very feasible when there is a wide range of the particle sizes in the mineral ...

elements that have the highest risk [2]. Primarily, tungsten is produced from scheelite and wolframite ores with 0.08 1.5% tungsten trioxide (WO 3) [3]. These tungsten minerals are friable in nature compared to the associated gangue minerals; hence, fine tungsten particles are excessively generated during the necessary comminution processes.
