How to Separate Gold from Pyrite
So far no account has been taken of the loss of gold which is contained in pyrites, as it has been assumed that these are saved by concentration if they are valuable, and this subject is dealt with in earlier. Nevertheless, as this gold comes under the head of non-amalgamable gold, its physical state and the causes of its disinclination to unite with mercury may conveniently be considered here

University of Minnesota’s Mineral Pages: Chalcopyrite
Chalcopyrite has a brassy yellow color that is distinct from gold’s more buttery yellow. Gold is also very ductile and easily deformed by pressure, whereas chalcopyrite is brittle and will shatter if struck. Finally, most specimens of chalcopyrite exhibit a slight, to a pronounced, iridescent tarnish that does not occur in gold. …

Chalcopyrite: Mineral Uses and Properties
The most obvious physical properties of chalcopyrite are its brassy yellow color, metallic luster, and high specific gravity. These give it a similar appearance to pyrite and gold. Distinguishing these minerals is easy. Gold is soft, has a yellow streak and has a much higher specific gravity. Chalcopyrite is brittle and has a greenish gray streak.
