The production of concentrates implies the crushing and later milling of the ore down to a particle size allows releasing copper by flotation. The concentrates from different regions have approximately between 24% up to 36% of copper. Copper concentrates are then submitted to a final filtration and drying process to decrease the humidity to 8-9%.

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.
Concentrate and copper marketing. Copper concentrates produced by mines are sold to smelters and refiners who treat the ore and refine the copper and charge for this service via treatment charges (TCs) and refining charges (RCs).
the region and wanted to prove up the concept of sulphide copper leaching at a commercial scale using the Albion Process TM A very cheap retrofit was undertaken on the existing oxide leach circuit and then fed a predominantly chalcopyrite/bornite concentrate (28-

In pyrometallurgy, copper concentrate is dried before being heated in a furnace. Chemical reactions that occur during the heating process cause the concentrate to segregate into two layers of ...
Copper, uranium, vanadium and other metals are produced by solvent extraction. The figure below is a simplified schematic of a typical copper solvent extraction process. Oxide copper ore, low-grade copper sulfide overburden, and other copper-containing materials are stacked into a heap.
Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.

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. In addition to copper, molybdenum concentrate, gold and silver are also produced by certain of FCX's North America copper mines.
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
