before chemists settled on the name **arsenopyrite**, German miners called this brassy iron-arsenic sulfide **mispickel** — a word of German origin that still surfaces in older mineralogical literature[1].\n\nThe modern name was coined in 1847 by the mineralogist Ernst Friedrich Glocker, as a contraction of *arsenical pyrite*[2]. Pyrite is the familiar iron sulfide the mineral visibly resembles; the *arsenical* prefix flagged the arsenic that distinguishes it. The new term was also a near-direct translation of the older German *arsenkies*, which had long sat alongside *mispickel* in mining and assay manuals. Both earlier names predate Glocker's coinage, and the mineral itself had been recognised and worked under them well before 1847[2].","claude-opus-4-7","1.7.0",{"markdown":935,"model_version":932,"prompt_version":933,"reviewed_at":11},"Arsenopyrite is, on paper, a principal ore of arsenic — its formula carries 46% arsenic by mass[1]. In practice, very little of today's arsenic comes from mining it. The metal is recovered primarily from the smelter dust of copper, gold, and lead refineries[2]. There it concentrates as an unwanted impurity in ores worked for other metals. When arsenopyrite is roasted in air the arsenic sublimes off as arsenic(III) oxide, leaving iron oxides behind[2] — but the same product falls out of copper smelting at much larger scale.\n\nThat leaves arsenopyrite's most consequential modern role outside the arsenic trade entirely. The mineral often hosts gold, locked inside its crystal structure so tightly that conventional cyanide leaching cannot reach it[3]. Such ores are called *refractory*. Recovering the gold requires a pre-oxidation step that breaks the arsenopyrite apart before cyanidation. Three methods are in industrial use: roasting in air, pressure oxidation in an autoclave, and bio-oxidation by acidophilic bacteria that metabolise the sulfide[4]. Each releases the gold; each also concentrates arsenic into a waste stream that has to be stabilised, not vented. For modern gold producers working refractory ore, arsenopyrite is the obstacle the whole flow sheet is designed around."]
