Maucherite is a very rare nickel sulfide mineral that was first discovered in 1956 in the Outokumpu ore deposit in Finland. This mineral has a complex chemical composition, and is named after German mineralogist, August Maucher. Due to its rarity, there are few synonyms for maucherite, and those that exist are highly technical terms primarily used in scientific settings. Some possible synonyms for the mineral might include nickel-arsenic sulfide, nickel-sulpharsenide, or arsenian nickeline. Other specific mineralogical names, such as millerite or heazlewoodite, may be used as related terms, but do not refer to the same mineral as maucherite.
