    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

  • 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
