Direct sulfide electrolysis extracts metal using less energy

Ores of metals including antimony, copper, nickel, and zinc are often compounds of sulfur. The metals are conventionally extracted by converting the ore into oxides by roasting at high temperatures, during which carbon and sulfur dioxide are emitted. The oxides are then converted to metals by heating them at temperatures over 1000°C.

Antimony metal and various antimony compounds (such as antimony trioxide and trisulphate) are produced from the ore. Exposure to antimony dust occurs during the mining, crushing and processing of the ore; however the highest exposures to both antimony dust and fumes are likely to occur in smelting and refining processes. Antimony is most ...
