The world's 20 largest copper mines produce nearly 9 million metric tons of the precious metal a year, about 40 percent of the world's total copper mine capacity. Chile and Peru, alone, account for about half of the copper mines on this list, but the U.S. does make the cut, with two mines among the top 20.
12.3 Primary Copper Smelting 12.3.1 General1 Copper ore is produced in 13 states. In 1989, Arizona produced 60 percent of the total U. S. ore. Fourteen domestic mines accounted for more than 95 percent of the 1.45 megagrams (Mg)
Miners indicate copper concentrations, although they may be spot checked by a third party when en route to the refiner. Additionally, penalties may be assessed against copper concentrate according ...
Copper ores containing chalcopyrite can be concentrated to produce a concentrate with between 20% and 30% copper-in-concentrate (usually 27–29% copper); the remainder of the concentrate is iron and sulfur in the chalcopyrite, and unwanted impurities such as silicate gangue minerals or other sulfide minerals, typically minor amounts of pyrite ...
This means that 95.7% of the copper present in the ore was recovered in the concentrate, while the rest was lost in the tailings. (c) The % Cu Loss can be calculated by subtracting the % Cu Recovery from : % Cu Loss = 100 – 95.7 = 4.3% This means that 4.3% of the copper …

Smelting: Then, copper concentrates are mixed with silica (sand) and limestone and heated in a furnace to form two naturally-separating layers. One layer is a waste containing iron and silica compounds and is discarded as slag slagByproduct left after a desired metal is thermally separated from its raw ore.. Approximately 75 percent of the ...
The value of the free copper, gold and silver in a copper concentrates for a copper smelter is depending on the recovery rate, LME copper price and LMBA gold and silver price. In this example the recovery rate for a copper smelter is 98.0%. The value of free gold and silver is normally greater than the value of the free metal for copper.
presses or vacuum filters (ceramic disk) the typical copper concentrate contains 25 – 35 % Cu and about 8 % moisture. The moisture content of the concentrate is a compromise between transporting water (cost) and avoiding dust generation during transport. Dewatered concentrates may heat
FCX operates seven open-pit copper mines in North America — Morenci, Bagdad, Safford, Sierrita and Miami in Arizona, and Chino and Tyrone in New Mexico. Molybdenum concentrate, gold and silver are also produced by certain of FCX's North America copper mines.

Copper in the USA: Bright Future Glorious Past Copper Producers. At the beginning of copper's flow through the economy are the mining companies, which process vast quantities of low-grade ore, mostly from open-pit mines in order to produce copper.
Bioleaching is the extraction of a metal from sulfide ores or concentrates using materials found native to the environment; namely, water, air and microorganisms. In other words, bioleaching is the commercialization of the ability of certain bacteria and archaea, found in nature, to catalyze the oxidation of sulfide minerals.
The anode copper, now 99.5 percent pure copper, is cast in copper anodes. Copper anodes are the output of the smelting process. SX-EW is an alternative method of producing purified copper from oxidized ores. In this process, a solution of sulfuric acid is poured over the copper concentrate, leaching the copper out of it.

In the case of copper, energy costs in most countries were about 30–35% of total expenses of smelters and refineries, and labour and other costs the remaining 65–70%. These figures agree with the cost structure suggested by ECORYS (ECORYS, 2011).
The capital cost of a CESL facility processing 50,000 tpy of high bismuth grade, copper concentrate was estimated to be in excess of $100M with an annual operating cost of $14M/yr. Economics were found to be breakeven for the remote, high-elevation refinery. The option was indistinguishable economically from
We produce copper, lead, nickel and zinc concentrates. The biggest source of raw materials for our smelters is metal concentrates. We also use certain intermediate forms and secondary materials. We purchase some of the raw materials from mines with which we have agreements.
