Copper extraction is distinctly profitable when the selling price of copper is above 6kg. It is unprofitable for some operations when the selling price falls below 3kg. At the former price, the industry tends to expand. At the latter, it begins to contract. The selling price of copper in mid-2011 was 9kg.

copper and the skin effect work together to reduce attenuation at high frequencies. Nickel coatingsare used for conductors that operate between 200 C and 450 C. At these high temperatures, copper oxidizes rapidly if not nickel plated. One drawback of nickel, however, is its poor solderability. Class B, C and D Copper Strand
