Dynamic material flow analysis of antimony resources in China
1. Introduction. Antimony is a hard, lustrous, silvery-grey metal. Antimony is unevenly distributed throughout the crust of the Earth, with China (32%), Russia (23%) and Bolivia (21%) as the top three countries in terms of their antimony reserves (Ding et al., 2021).It is extremely difficult to beneficiate antimony since the average abundance of …

Antimony Metallurgy | SpringerLink
The powdery crude antimony trioxide is reduced by a carbonaceous reductant in a reverberatory furnace at 1,000–1,200 °C to produce crude antimony. Crude antimony can be produced by the precipitation smelting process. The typical pyrometallurgical antimony production process using sulfide ore is shown in Fig. 1.
