Copper concentrators typically treat up to 100 000 t of ore per day. They are located directly at the mines to achieve low transport costs. The copper recovery efficiency is over 90 %. About 95 % of the ore input goes into the tailings, which are stored in large dams near the mine and are used for water recycling to the flotation stages.

and auxiliary equipment for the processing circuit. A diesel-powered generator would burn about 100 gallons or more per day to process an equal amount of ore. Based on hydrogen's energy-to-weight ratio (2.8 times greater than fossil fuel) it is estimated that 60 pounds per ton of zinc will produce enough hydrogen to operate the
than 55,000 tons of ore per day and produce 591,000 pounds of gold per year. The operator hired several contractors and subcontractors to construct the mine on a fast track within five months. The operator approached Anixter with a bill of materials including the copper and fiber cable, switches and cabinets it needed for the project.

Reserves. Copper is a fairly common element, with an estimated concentration of 50–70 ppm (0.005–0.007 percent) in earth's crust (1 kg of copper per 15–20 tons of crustal rock). A concentration of 60 ppm would multiply out to 1.66 quadrillion tonnes over the 2.77e22 kg mass of the crust, or over 90 million years' worth at the 2013 production rate of 18.3 MT per year.
