Total Materia - Copper Grades

Copper grades are divided into six families: coppers, dilute copper alloys, brasses, bronzes, copper-nickel alloys, and nickel-silver alloys. The first family, the coppers, is essentially commercially pure copper, which normally is soft and ductile and contains less than about 0.7% total impurities.

Thus for a copper–molybdenum mine, the percentage head grade of copper would be increased by adding the percentage of molybdenum in the milled ore multiplied by the ratio between the price of molybdenum and the price of copper. Similar calculations are made for mines containing gold, silver, cobalt, nickel, platinum group metals, lead and zinc as well as copper.
