Analysis of the current technical solutions for the processing of iron ores showed that the high-grade ores are directly exposed to metallurgical processing; by comparison, low-grade ores, depending on the mineralogical and material composition, are directed to beneficiation including gravitational, magnetic, and flotation processes or their As one of the most important strategic rare metal (Mohan 2010), bismuth has been widely used in electronics, medical treatment, military and other high technologies fields (Kumar et al. 2021). Sodium sulfide has been widely used as a bismuth depressant in the flotation separation of molybdenum–bismuth sulfide ores. However, the selectiveDepression Mechanism of Sodium Sulfide in Flotation

The 1-hour and 2-hour tests resulted in a lead bullion containing 0.47 percent bismuth and 0.13 percent bismuth, respectively, while in the 3-hour test, bismuth was decreased to 0.03 percent. The amount of lead recovered was comparable for all three tests. The centrifuge was operated for times of 5, 10, and 20 minutes.Flotation cells can be divided in two groups: mechanical and pneumatic machines. The first group comprises the traditional cells which employ a mechanical agitation, and the second group is related to pneumatic cells which do not have mechanical devices for maintaining the slurry under agitation.
