The average grade of copper ores in the 21st century is below 0.6% copper, with a proportion of economic ore minerals (including copper) being less than 2% of the total volume of the ore rock. A key objective in the metallurgical treatment of any ore is the separation of ore minerals from gangue minerals within the rock.

Iron ores that contain less than 50 percent iron are usually concentrated (to 60 percent iron) by magnetic separation or gravity dressing. Powdery and sulfurous (> 0.3 percent sulfur) rich ores, as well as beneficiation concentrates, are made into lumps by sintering; so-called pelleted iron ore is made from concentrates.

into a concentrate having approximately 20 percent copper. Also included in the concentrate are sulfur, iron, and a number of impurities that are hazardous air pollutants (HAPs), including arsenic, lead, cadmium, cobalt, manganese, nickel, selenium, antimony, beryllium, and mercury. Copper concentrate is the input to the smelting process.

Copper processing, the extraction of copper from its ores and the preparation of copper metal or chemical compounds for use in various products. In its pure form or as an alloy, copper (Cu) is one of the most important metals in society.

Currently the most common source of copper ore is the sulfide ore mineral chalcopyrite, which accounts for about 50 percent of copper production. Sulfide ores are processed via froth floatation to obtain copper concentrate. Copper ores containing chalcopyrite can produce a concentrate with 20 to 30 percent copper in concentrate.
