This substitution process may lead to a change in the Sb concentration in the slurry.
In the metallurgical process, the extraction of lead and antimony metals from jamesonite is also one of the difficulties in industrial production due to the similar thermodynamic characteristics of a lead-antimony binary system (Derakhshan et al., 2005). The smelting process can separate Pb and Sb of jamesonite.
Stibnite is a mineral that is also known as Antimonite because of its antimony sulfide composition that gives it shape. Stibnite is also a lead-gray mineral with a long and pointy shape (similarly looking like the throne in Game of Thrones). Given these descriptions, handle your Stibnite with the utmost care, and do not let it touch your skin.
