Antimony is a silverly, lustrous grey metal that exhibits poor heat and electrical conductivity. It is relatively soft, measuring only 3.25 on Moh's scale of mineral hardness. Known as "stibium" in classical Latin, antimony is represented by the chemical symbol Sb. A member of the arsenic group of elements, antimony is commonly found in ...Web
Antimony (Sb) is an impurity element that is increasingly encountered in the mineral processing/metallurgical industries of gold, copper and lead. Its occurrence in metallurgical feedstocks is in the form of various antimony minerals with stibnite, Sb 2 S 3, being the most important one. During processing antimony is mobilized reporting to ...Web
