The need for depressants depends on the liberated gangue minerals occurring in the stibnite ore. Sodium cyanide has been usually employed to depress gangue minerals such as pyrite (Bhatti et al., 2014; Brinker, 1935) and arsenic-bearing minerals including arsenopyrite and gersdorffite (Davis et al., 1986; Lager and Forssberg, 1989b).

The primary sources of antimony extraction are stibnite (antimony trisulfide) and valentinite (antimony xide). The extraction process typically involves several steps, including mining, concentration, and smelting.
The extraction of antimony involves both underground and surface mining methods, depending on the ore deposit's characteristics. After extraction, the ore undergoes crushing and flotation processes to concentrate the antimony content. The concentrate then goes through a smelting process to produce antimony metal or antimony oxide.
