SUGAR LAND--May 31, 2013--Written by John Egan for Industrial Info Resources (Sugar Land, Texas)--Capital and maintenance activity at copper mines and mills is scheduled to surge over the next two years, as producers get comfortable with copper prices above the $3 per pound mark. Copper prices hit a five-year low of $1.50 per pound in early 2009, then jumped to a five-year high of $4.50 per pound in 2011. While the metal has come down off those highs, it had traded above $3 per pound for two years.
