Feb 14, 2014That's all the more impressive considering the accompanying decline in the richness, or grade, of the ore being mined. Anyone extracting a mineral resource goes for the richest, most easily mined deposits first, so ore grades ran from 10% to 20% copper until late in the 19th century and then plummeted to 2% to 3% in the early 20th century.
This is partly because Zambia's own copper production, at a little over 800 000 tonnes, is more than 20% lower than where it should be, due to the years of policy instability. Running a smelter half full is both a waste of income and particularly costly, as the asset value of a plant depreciates regardless of production levels.
