copper, lead, zinc, antimony, and arsenic in pakistanall lead localities found to date are of minor importance; there has been small production at one .locality in chasai district and in the southern part of the hazara district. zinc, antimony, and arsenic are sparse in pakistan and no important localities of these metals are reported.tetraethyllead tetraethyllead (commonly styled tetraethyl lead), abbreviated tel, is an organolead compound with the formula (ch 3 ch 2) 4 pb.it is a petrofuel additive, first being mixed with gasoline beginning in the s as a patented octane rating booster that allowed engine compression to be raised substantially. this in turn caused increased vehicle performance and fuel economy.the global flows of metals and minerals usgszinc during the 35 period are shown individually (fig. 3). aluminum consumption increased by more than three times, the most dramatic increase of the nonferrous metals, while copper and zinc consumption increased about twof. lead consumption increased the least during the period, about one and a half times.
