Generations of Ahtna people collected native copper found in the Wrangell Mountains, working it into art, utensils and arrowheads. Prospectors fooding into the area in the wake of the '98 Gold Rush knew there was copper as well as gold in these mountains, so it was no surprise when the Bonanza Mine was discovered in 1900.

For example, in the Kamoa mine in the DRC nearly 70% of mineralogy consist of the high copper content bornite, covellite and chalcocite. The above-mentioned mineralogy results in concentrate quality at above ~60% copper content. Finally, the copper rich minerals include significantly less iron, which drives a quality challenge at the process plant.

also use diesel fuel for surface hauling of ore to the mill. Approximately 155 pounds of explosives are used for every short ton of copper produced in underground mines.s The average grade of the ore mined, the ratio of overlying dirt and rock (overburden) to the ore body (stripping ratio), and the depth of the pit 5Gaines, supra note 3.

For example, the copper content of a good grade copper ore may be only one quarter of one percent. The gold content of a good grade gold ore may be only a few one-hundredths of a percent. Therefore, the next step in mining is grinding (or milling) the ore and separating the relatively small quantities of metal from the non-
