1. Background. Antimony is a silvery, white, brittle, crystalline solid that exhibits poor conductivity of electricity and heat. It has an atomic number of 51, an atomic weight of 122 and a density of 6.697 kg/m 3 at 26 °C. Antimony metal, also known as 'regulus', melts at 630 °C and boils at 1380 °C.Antimony and the natural sulfide of …

Dead roasting is the most commonly used roasting process and is mainly applied in our zinc roasters. When using a dead-roasting process for concentrates, the sulfides are completely transformed into oxides. The gas temperature in this type of plant is typically between 900 and 950°C. The hot gas generated in the process is used for heat recovery

ondary production of antimony is mainly restricted to the recycling of antimony-containing lead alloys from lead-acid battery recycling plants [3]. However, interesting future secondary sources could include industrial residues (e.g., mine tailings, process residues, manufacturing scrap) from the production of lead, copper, gold, and antimony [7].
