Fool's Gold and Real Gold
Chalcopyrite (a copper iron sulfide) has very similar properties to pyrite. It has a lower hardness than pyrite (3.5 to 4) and a lower specific gravity than pyrite (4.1 to 4.3), but the same tests can separate chalcopyrite from gold.

1911 Encyclopædia Britannica/Pyrites
When employed as a group-name the constituent species are distinguished by prefixes: thus the type is called iron pyrites, whilst other species are known as copper pyrites, arsenical pyrites, &c. The original word pyrites (from Gr. vriip, fire) had reference to the fact that sparks might be elicited on striking the mineral violently, as with ...

Pyrite: Fool's Gold with a Heart of Metallic Brilliance
Pyrite, commonly known as "fool's gold," is an iron sulfide mineral that has been used and valued by humans for centuries. With its brassy yellow color and metallic luster, pyrite has a superficial resemblance to gold, leading many amateur collectors and miners to mistake it for the precious metal.However, while pyrite may not contain gold …
Copper-arsenic decoupling in an active geothermal …
Over the past few decades several studies have reported that pyrite hosts appreciable amounts of trace elements which commonly occur forming complex zoning patterns within a single mineral grain. These chemical zonations in pyrite have been recognized in a variety of hydrothermal ore deposit types (e.g., porphyry Cu-Mo-Au, epithermal Au deposits, …
Chalcopyrite | Common Minerals
Some economic chalcopyrite deposits form as hydrothermal fluids dissolve copper from igneous rocks and then precipitate it in surrounding contact-metamorphosed sedimentary rocks. Chalcopyrite is most often found with pyrite and other sulfide minerals, as well as sphalerite, galena, dolomite, tourmaline or quartz.
