ore antimony sulfide

Antimony Statistics and Information | U.S. Geological Survey

The natural sulfide of antimony was known and used in Biblical times as medicine and as a cosmetic. Antimony in its elemental form is a silvery white, brittle crystalline solid that exhibits poor electrical and heat conductivity properties. Commercial forms of antimony are generally ingots, broken pieces, granules, and cast cake.

antimony | Definition, Symbol, Uses, & Facts | Britannica

Antimony is a lustrous silvery bluish white solid that is very brittle and has a flaky texture. It occurs chiefly as the gray sulfide mineral stibnite (Sb 2 S 3 ). History The ancients were familiar with antimony both as a metal and in its sulfide form. Fragments of a Chaldean vase made of antimony have been estimated to date to about 4000 bce.

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.
