Alluvial mining for platinum is discussed less often than alluvial mining for gold and diamonds, and it has a shorter history. According to Johnson Matthey (LSE:JMAT), alluvial deposits of platinum were first mined in Russia's Ural Mountains back in 1823, and although they were the most dominant source of platinum by the end of the 19th ...
