Thus, electrical energy is an acid (incoming from previous stages of leaching and solvent important cost factor in copper EW plants. extraction) are reduced on cathode surfaces as pure metallic The production level and energy efficiency in copper EW copper using high dc currents. In this way, copper ore impu- processes are determined by the following: 1) the current ef- rities are not,Chapter 7 Energy Use in the Copper Industry,Energy Requirements in Proven and New Copper Processes,re- port prepared for the U.S. Department of Energy, contract no, EM-78-S-07-1 743, December 1980. The hypothetical open-pit mine described in table 7-2 uses an average of 20 million Btu of energy per ton of cathode copper produced, or about 21 percent of the energy consumed in pro-Copper in Sustainable Energy,Copper is an integral part of renewable energy systems and equipment because of its reliability, efficiency and performance. The use of copper wiring, tubing, busbar, cable, bushings, bearings and myriad electrical and mechanical parts keeps these systems operating longer, and at higher efficiencies. This allows the increased power that is generated
Energy and Environmental Profile of the U.S. Mining Industry 5.1.3 Copper Processing Prior to pyrometallurgical, the ore (which often contains less than one percent copper) is crushed and ground with water and placed in a concentrator. The rock/water slurry is subjected to physical and chemical actions (i.e., air sparging and hydrophobic chemicalEvaluation of energy efficient distiller/concentrator,,Both plants use vertical pressure tube reactors, in which heat is transferred to boiling light water, as heat sources. A part of the energy in the steam is converted to electrical energy in steam turbinegenerators; the energy in the turbine exhaust steam is used to heat sea water in the turbine condensers. The sea water flows to an adjacent distillation plant for the production of fresh water. Two plant sizes areCOPPER Copper production - Repository,The copper recovery efficiency is over 90 %. About 95 % of About 95 % of the ore input goes into the tailings, which are stored in large dams near the mine and are used for

At Kennecott, we continue to look for new ways to improve energy efficiency and increase our on-site-generated power supply. The $10 million, 6.2 MW combined heat and power (CHP) system – large enough to power 6,000 average-sized homes – is one example of how we are doing this: Generating enough power to supply up to 50% of the electrical needs of the refinery.
