Antimony

Antimony is identified by  atomic number 51 and symbol Sb (stibium) alongside lead (Pb), tin (Sn) and bismuth (Bi). It is mainly sourced in China and Myanmar in its sulfide mineral stibnite form. As a metalloid, it has a combination of metal and non-metal properties, which makes it a very versatile element. The oldest recorded use of Antimony is as kohl (cosmetic) during biblical times, in ancient Egypt and Southern Asia. Since then, many more forms and uses of Antimony have been developed and identified.

According to the international Antimony Association,   World Antimony resources were estimated at 5 million tons in 2011 by Bio Intelligence Service (2015). According to USGS in 2016 the world Antimony reserves amounted to 2 million tons, 80% of which is concentrated in three countries: China, Russia, and Bolivia (USGS, 2016).

The annual globally mined production of Antimony is approximately 175,500 tons (BGS, 2015), most of which is extracted in China and Myanmar.  Antimony is furthermore a co- or by-product of the production of gold, lead, copper, and zinc.

The pie chart provides an overview of the main uses of Antimony.  In all applications, only relatively small quantities of Antimony are needed to achieve the required function.  Even in such small quantities, Antimony enables the availability and performance of significant quantities of articles which are indispensable to society:

• Flame retardant textiles and plastics (43 million tons in 2015 (PlasticsEurope, 2016) which are crucial in saving the lives of millions of people
• PET resin used to produce PET bottles and many more lightweight recyclable food packaging materials helping to maintain the original properties of their contents (27.8 million tons in 2015 (PlasticsInsights, 2016)
• Polyester textiles used in fashion, domestic, automotive, IT hardware, and industrial applications
• Lead-based batteries which remain the most cost-efficient rechargeable batteries (demand of 478 million KVAh in 2014 – PR Newswire, 2016)
• Lead-based alloys, which enable cost-efficient solutions for construction, ammunitions, weights, solders, pewters, fusible alloys, and radiation shields
• High purity and transmission flat glass (global photovoltaic glass consumption reached 580 million m² in 2015 – Globe Newswire, 2017) which promotes increased sustainability in both energy production and consumption solutions
  … to name just a few.
