Pyrites is a kind of stone that mixes sulphur with a metal — most often iron, sometimes iron and copper. Iron pyrites is brassy yellow and shiny, so people have long taken it for gold and then felt foolish; English also calls that kind fool's gold. If you strike it, it can spark, which is how it got a “fire” name. You meet the word in geology and in old mining stories more than at the dinner table. Though actually, pyrites looks plural, and scientists often say pyrite for the iron one and another name for the copper-iron one. In looser English, pyrites still covers that sulphur-and-metal mix.
黃鐵礦(鐵的那種,俗稱愚人金);含銅的是黃銅礦
組成From Greek, basically a “fire-stone”, because it can spark. The fire piece is the same Greek pyr you meet in pyre. I am sure of that broad story; I will not pretend to recite a longer Latin path.
