Gold in porphyry copper deposits: its abundance and fate ...

Gold abundances in porphyry copper deposits vary greatly, complicating efforts to define gold-rich porphyry copper deposits. The original definition was based on the Au/Mo ratios of porphyry copper deposits with no reference to their copper content, and resulted in the suggestion that gold-rich deposits were found largely in island arc regions (Kesler, 1973).

Copper Mining and Extraction Sulfide Ores

The main ores of copper are sulfides and oxides. From their chemical formulas you can calculate the percentage of copper in each mineral.
