Antimony SmeltingsciencedirectWhat is antimony ore processing?Like most mineral processing, antimony ore processing consists of ore crushing, grinding, classification (gravity separation and cyclones) and flotation. The feed ore typically contains stibnite along with other gangue minerals. In China, it is pyrite, quartz, calcite, barite, kaolin, and gypsum.Antimony in the metallurgical industry: A review of its chemistry and
sciencedirectIs Antimony mining a risk factor for supply disruptions?From 1990 to 2018 antimony mining was highly concentrated. The vertical integration of the largest mining and refining companies in 2018 also indicated a lower diversity of supply on a company level. We found that based on production volume, most antimony is mined as a by-product, which increases the vulnerability to supply disruptions.Resilience in the antimony supply chain
sciencedirectWhat is antimony used for?While societies from thousands of years ago used it in the form of stibnite for decoration, in modern times it is used to make semiconductor devices, batteries, low-friction metals, cable sheathing and flame-proofing materials, paint, ceramic enamels, glass and pottery. The traditional method of producing antimony metal is through heat smelting.MIT's accidental smelting discovery unlocks the potential of antimony
