Chalcopyrite is a copper iron sulfide mineral that crystallizes in the tetragonal system. It has the chemical formula CuFeS2.
Chalcopyrite has
electrical characteristics suitable for use as a detector in Crystal Radios.
The "Perikon" Crystal Radio detector for example used two minerals, A Fixed Cup Chalcopyrite and
Zincite
or Bornite in the movable section.

It is also possible that
Chalcopyrite will also work in a standard cat whisker detector stand but may require some type of circuit biasing.
