economic grade of lead ore

In concentrating an ore containing these minerals it is usually desirable to recover the lead and the copper in one concentrate the perfect grade of which would be 100 galena plus chalcopyrite If “L” is the lead assay of the crude ore and “C” the copper assay it is easily shown that the ratio of concentration of perfect concentration is
