Copper is produced in the U. S. primarily by pyrometallurgical smelting methods. Pyrometallurgical techniques use heat to separate copper from copper sulfide ore concentrates. Process steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining. 12.3.2 Process Description2-4

The concentrate is a finely milled, dark gray material containing about 30 % copper (Cu), 30 % iron (Fe) and 30 % sulfur (S). The concentrate also often contains small amounts of precious metals and a range of other elements, which we process in the smelters.
PROCESS DESCRİPTİON Copper is leached from the concentrate by atmospheric reactor leaching, purified with copper solvent extraction and finally recovered through the traditional sulfate based copper electrowinning as shown in figure 1.
There are 458 processing of copper concentrate suppliers, mainly located in Asia. The top supplying country is China (Mainland), which supply of processing of copper concentrate respectively. Processing of copper concentrate products are most popular …

This is the same process for both copper and molybdenum porphyries. The smelter is basically a large furnace which melts the concentrate and drives off the sulfide to leave molten copper metal this is still contains impurities and it needs to be refined further to make it a salable product.
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.
The process of extracting copper from copper ore varies according to the type of ore and the desired purity of the final product. Each process consists of several steps in which unwanted materials are physically or chemically removed, and the concentration of copper is progressively increased.
Specifically, for the copper production partitioning of 210 Pb and 210 Po from uranium occurs into the copper concentrate during the smelting process. These radionuclides are vaporized at the smelting stage and may accumulate in dusts collected from off gases.

Copper concentrate smelting is a large scale, intensive process consisting of four stages: sulphur in the sulphide minerals is "burnt-off"; the metals are melted to form a "matte" and the waste material forms a "slag"; copper in the matte is electro-refined to copper metal; and the gold/silver is refined to doré.
The patented Alkaline Leaching (AL) process selectively leaches arsenic and antimony. Copper, lead and nickel are not solubilised (dissolved) in the process. The final product from the process is a cleaned saleable copper, lead or nickel concentrate – no expensive downstream metal …

These deposits eventually lead to tissue necrosis and fibrosis, causing a variety ...
Most copper ore currently being mined contains copper mainly as chalcopyrite. Since chalcopyrite by itself is only about 35 percent copper, it is difficult to upgrade a concentrate by flotation to more than about 25 to 28 percent copper without losing a significant amount of copper during the cleaning steps.

The Verti-Press filter is used at the end of the concentrator cycle to filter and dewater the copper slurry prior to the drying cycle and the smelting process. Prior to the Verti-Press Filter technology, Falconbridge used rotary vacuum drum and thermal dryers to filter, dewater and dry the copper concentrate slurry.
