To be more specific, let us take the example of a copper ore whose grade, or copper content, is only 1% by weight. Let us assume that the sole copper mineral species in this ore be chalcopyrite, which is one of the most popular copper minerals found in copper ores in our planet. The chemical formula of chalcopyrite is known to be CuFeS2.
