It can be seen from Eq. () that Sb 2 S 3 is deposited on the surface of gold particles, forming a dense product layer and hindering the diffusion of CN − and O 2 to the gold particles, leading to low leaching ratio [3, 4].Effect of Antimony on Pretreatment Process. The melting point of antimony compounds, generated in the roasting process …

This explains the name and logo. Antimony is the 51st element on the periodic table and it is known as the "wolf of metals", devouring everything except gold. According to Rob, antimony bonds well with other materials and was used to purify gold during the age of alchemy. Hence, the double wolf head symbolizes being "bonded by …

Antimony Metallurgy. Antimony metallurgy is the technology that extracts antimony metal from antimony ores or produces antimony compounds. Antimony was discovered in the ancient time, and its name was derived from antimonite. In 1604, a process was invented to extract antimony and antimony sulfide as described by B. …

The yield and antimony content of the leaching residue were 92.0% and 0.23%, respectively. Compared with the leaching of clairite (Celep et al., 2011) and jamesonite (Yang et al., 2005) in the alkaline sodium sulfide system, a higher antimony recovery was obtained for the antimonial refractory gold ore.

4.1. Cellular Mechanisms Associated with Antimony Entry and Processing. Antimony enters the cells via aquaporin channels [207,208,209]. More specifically, it has been proven that Sb(III) enters the cells through the GlpF aquaporin channel in Escherichia coli, the same channel that mediates the entry of As(III) into that organism [210,211].
