BGS Risk List (3)


If our countdown were in the leagues of the Olympics we would now be onto our bronze position element. Narrowly missing out on a podium spot last week was bismuth, but coming in 3rd place is antimony!


RANKING:
3

ELEMENT NAME AND SYMBOL:
Antimony (Sb)

RELATIVE SUPPLY RISK INDEX:
9.0

WHY?:
As will be seen below antimony is emerging as a much needed element due to its application in microelectronics. China holds 85% of the world’s deposits and accounts for 90% of the production, which is a huge proportion! Coming in at second place South Africa accounts for just 2.2%.

LEADING PRODUCER:
China

TOP RESERVE HOLDER:

China

WHY THE DEMAND?:
Antimony has few uses but is very much in demand for them. 60% of resources go into the production of flame-retardants, which are commonly integrated into children’s clothes and toys as well as aircraft and car seat covers. The remaining 40% is taken up by lead alloys, which are used in lead-acid batteries; as a fining agent to take bubbles out of glass; and as a pigment. Recently its use is growing in semiconductors and microelectronics, an application likely to grow.
