The antimony diversity of supply of both mining and refining is low. • Almost 70% of Sb is mined as by- or co-product. • Companion metals can both have higher and lower resilience. • An additional 25% of Sb production comes from post-consumer recycling. • Stockpiling has played a role in dampening and exacerbating supply disruptions.

The processes of parting may be tabulated as follows: Cementation. Melting with sulphide of antimony. Melting with sulphur, and precipitation of the gold from the regulus by silver, iron, or litharge. Parting by nitric acid. Parting by sulphuric acid, sometimes called "refining.". A combination of these last two methods.

The next stage in refining is the softening process where arsenic, antimony, tin, and other elements are removed by oxidation into a lead oxide-rich slag. In this operation, oxygen or oxygen-enriched air is injected into a pot held at around 600 °C. The resultant softened metal contains around 0.003% arsenic, 0.04% antimony, and <0.001% tin.
