Antimony is classified as a critical/strategic metal. Its primary production is predominated by China via pyrometallurgical routes such as volatilization roasting—reduction smelting or direct reduction smelting. The performance of most of the pyro-processes is very sensitive to concentrate type and grade. Therefore, technology …
Depending on the grade of antimony in the concentrate, different pyrometallurgical methods can be used to extract antimony . For low-grade ores (5–25 …
In this series of tests, batch pressure leach tests were conducted with a low-arsenic, low-antimony concentrate (Concentrate C) blended with antimony sulphide (0 to 12%). These concentrate blends were added to the laterite ore at about 23.0% of the total solids to provide the acid required for the leaching of the concentrate and the laterite ore.
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 ...
