IDENTIFYING OPPORTUNITIES TO REDUCE THE

Providing information on energy use is only partially solving the problem of determining new opportunities to reduce energy use, and in turn comply with EEOs. Along with energy use, information’s required on what is actually happening in the plant at the time, in other words there has to be context supporting the energy use. For example near real

Primary production uses about 170 x 10/sup 12/ Btu total energy annually (about 100 x 10/sup 6/ Btu/ton pure copper produced from ore). Mining and milling use about 60% of the total consumption, because low-grade ore (0.6% copper) is now being mined. Most copper is extracted by smelting sulfide ores, with concomitant production of sulfur dioxide.
