But flotation methods of concentrating copper ores have created a difficulty in the use of the blast furnace. The great rush of air in this type of furnace tends to blow finely-divided ore into the flues, necessitating ex pensive after-treatment and recovery of the flue dust. This diffi culty has to some extent been overcome by the development of the roasting and sintering machines such as

Copper Mining and Extraction: Oxide Ores
Copper is refined from ores in the ground, either through underground or open-pit mines. Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction: Sulfide Ores (11–14), but is introduced here because an important by-product of this process is used for the extraction of oxide ores. Pyroprocessing

Copper Ore an overview ScienceDirect Topics
The principal copper ore mineral is chalcopyrite (CuFeS 2), which is commonly smelted to yield a matte containing ∼50% copper. In the presence of silica flux, iron is selectively oxidized to a slag. Figure 14 shows a PSD for the Cu–Fe–S–O system at 1 atm SO 2 as a function of temperature (Rosenqvist 1978). Unlike the system for lead, the copper and Cu 2 S melts are nearly immiscible

Detailed production data for the year 2010 has been used to populate the inventory model for the copper ore extraction, and both the copper oxide and sulphides ore processing. For the few unit processes, where specific data for the “Cerro Bonito” facilities has not been available, the relevant information was estimated from other non-confidential data sources. Smelting facilities are

Copper: How it is Sold and Priced MarketCap
Copper concentrates are produced by the beneficiation, or upgrading, of copper ore. A typical copper ore would be 0.7% to 2% copper, a typical copper concentrate would grade around 25% to 35% copper. Copper concentrates are either smelted and refined in-house, or sold to custom smelters. The concentrate may be smelted to produce blister copper for sale to a custom refinery, or the blister
