The extraction of antimony involves both underground and surface mining methods, depending on the ore deposit's characteristics. After extraction, the ore undergoes crushing and flotation processes to concentrate the antimony content. The concentrate then goes through a smelting process to produce antimony metal or antimony oxide.

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.Stibnite was used in ancient Egypt …
Further, Niehuser pointed out that the U.S. has an inadequate supply of antimony in its National Defense Stockpile, 1,100 tons at the end of last year, according to the USGS. In comparison, the U.S. consumed 22,000 tons of antimony in 2023. The analyst approximated that Stibnite could backstop about half of U.S. antimony consumption for six years.
Lead - Antimony alloys have high corrosion resistance in most enviroments. They form a protective, impermeable film even faster than pure lead and in some cases even faster than chemical lead. It is found that except in the presence of florine compunds, 6% antimonial lead is more resistant to corrosion than is soft lead. 6% Antimony, 92% Lead this is by far the most …
Antimony is a metalloid. A metalloid is an element that has characteristics of both metals and non-metals. The metalloids can be found on either side of the staircase line on the right side of the periodic table (with the exception of aluminum, which is not considered a metalloid). Antimony is primarily used in alloys, ceramics and glass, plastics, and flame retardant materials.
