    mineral chalcopyrite. Students paper Help

    Chalcopyrite is a sulfide mineral so this means it contains more than just copper. In addition to sulfur (S), chalcopyrite contains some iron (Fe) and the proportions of these metals in the mineral are expressed by its chemical formula: CuFeS2.

    Copper mining. Introduction.

    The main ores of copper are: chalcopyrite bornite malachite. The ores are extracted by either traditional mining (open pit or underground) or by leaching. The copper is then recovered using physical and chemical techniques. In this electronic resource, we'll look at the ways in which copper is mined and recovered from its ores.

    Chalcopyrite: The mineral chalcopyrite information and ...

    The Mineral chalcopyrite. " Peacock Ore " which is sold to many amateur mineral collectors often as a variety of Bornite, is in fact almost always Chalcopyrite treated with acid to produce an iridescent tarnish. Though some Chalcopyrite is naturally iridescent, wild colors such as strong blues and purples are usually formed from acid treatment.

    Copper Mining and Processing: Processing of Copper Ores ...

    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.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...

    "Chalcopyrite Mine" in Jefferson, MT, Copper Producer ...

    Copper deposits are documented at "Chalcopyrite Mine." Copper is present at a grade sufficient to have a strong effect on the economics of an excavation project. It may even be viable as the only commodity mined. At the time this deposit was surveyed, there was a tapped production. Mining opporations could be year round, intermittent, or seasonal.

    Copper extraction

    Copper ores containing chalcopyrite can be concentrated to produce a concentrate with between 20% and 30% copper in concentrate (usually 2729% copper); the remainder of the concentrate is iron and sulfur in the chalcopyrite, and unwanted impurities such as silicate gangue minerals or other sulfide minerals, typically minor amounts of pyrite, sphalerite or galena. Chalcocite concentrates typically grade between 37% and 40% copper in concentrate

    Chalcopyrite is an accessory mineral in Kambalda type komatiitic nickel ore deposits, formed from an immiscible sulfide liquid in sulfide saturated ultramafic lavas. In this environment chalcopyrite is formed by a sulfide liquid stripping copper from an immiscible silicate liquid. Occurrence. Chalcopyrite is the most important copper ore.
