China has near global monopolies on these exports, accounting for 98% of global gallium production, 93% of germanium production, and 49% of antimony production.

    Antimony is a rare earth mineral needed for the production of all modern artillery shells. The US has no antimony mines. China controls its extraction and owns like 90% of the mines in Hunan province. Other mines are located in Russia and South Africa. Bolivia is the second highest producer behind China. Pretty much no other nation produces it. That’s it. Four countries.

      While Antimony is certainly rare (contextually) and an earth mineral, using those terms are incorrect in the greater sense - One shouldn’t confuse it (as another reply did) for a ‘rare-earth metal’ or rare-earth element (REE) which is a wholly different group of elements with geo-political contexts.

      Antimony is a metalloid (not quite a metal) and is about as scarce as silver, tin and iodine in the Earth’s crust.

        Thanks for the context. Additionally, whether or not a metal is rare is a lot less important as to whether or not it can be found in concentrations good enough for extraction on an industrial scale. That’s where Hunan province comes in. They got the mines with the concentrations to make it worthwhile and they’ve got the economic and political willpower to get those mines running because it’s what they need. For that to happen in America we’d literally need to fully fund these publicly but of course we’d keep any profits private. Think of all the corruption and inefficiency you can imagine and there you’d have it.

      The US national stock pile is set to be depleted in 2025.

      It’s fucking crazy such a simple weapon hasn’t been simplified in its supply chain demand for over 100 years. Antimony is literally used to harden the metal casings of the shells. That’s fucking it. Seriously. That’s fucking it. For 100 years the greatest most capitalisticalist empire on earth couldn’t figure out how to more sustainably harden artillery shells without using a rare earth metal.

        It’s also a component for stable and reliable fuses.

        But yeah, I agree. You’d think there would be other options. There probably are. But in America’s hubris they most likely presumed they could just bully anyone into being suppliers for these materials.

          Ironically this isn’t the first time it’s had this problem. Japan stopped giving it to them around WW2.

      Antimony is a rare earth mineral needed for the production of all modern artillery shells.

      looked this up to find out what it goes into and apparently it is the best hardener for alloying lead
