Similarly, in a copper or lead ore carrying gold associated with pyrite, it might be profitable to make an iron concentrate containing the gold. If the gold and silver can only be brought up in the desired concentrate by contaminating it with unwanted mineral, the mode of procedure must be determined by the economics of the case.
