  • Rock Mineralogy Oxide Copper Ores

    Several types of core leaching experiments have been designed to model the in situ systems of interest (Paulson, 1989). The main components of the experimental apparatus are non-reactive with the sulfuric acid leach solutions used in the experiments. The apparatus used for the experiments described in this paper consisted of an acrylic reaction cell in which the core was placed, and leach

    Table 1 shows copper heap leach mineralogy issues for rock and alteration minerals for oxidised copper ores, expressed in terms of the following parameters: Oxide/sulphide class e.g. oxide rock, oxide alteration, sulphide rock, precipitates, alteration products and original rock minerals in equilibrium with leach solution Mineral type, property

  • Copper Mining and Extraction: Oxide Ores

    Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in The process used to treat sulfide copper ores begins at the mine site, where the copper-bearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth

    oxide copper minerals is a function of source-rock and host-rock mineralogy, pyrite and other (copper) sulfide abundance and distribution, fracture density and distribution, phreatic and/or vadose zone occurrence and stability, and maturity of the weathering profile. The paragenesis of copper oxide mineral formation reflects local, dynamic changes in supergene solution composition

    The porphyritic stock at the center of the system may not contain enough of the copper minerals to be an ore deposit. The rock that surrounds the stock however may be rich in copper mineralization. Below: Eh-pH diagram for a copper deposit. Oxidation and reduction (Redox) reactions play an important role in the geochemical processes that produce enrichment of ores. Eh is a measure of reduction

    17/3/2017· Cuprite is a copper oxide, Cu 2 O, and an important ore of copper found in weathered zones of copper ore bodies. (more below) Cuprite is the compound cuprous oxide, with the copper in a monovalent state. Its Mohs hardness is 3.5 to 4. Its color ranges from the dark red-brown of this copper ore specimen to the spectacular crimson and scarlet shades you'll see in rock-shop specimens.

    Collectable Copper Ores and Minerals. This is a selection of the most commonly collected copper ores. Also included are a few other interesting ores of metals often alloyed with copper such as zinc, lead and bismuth. Illustrations are being added where available. The descriptions are mostly those of the vendors and give some of the fascinating background to the collection. They cannot always

    A copper ore is a mixture of copper minerals and other materials in the rock called gangue, from which it is economically viable to extract the metal. A typical copper ore contains between 0.5% and 2.0% copper. A high grade ore produces a high yield of metal. A low grade order produces a low yield of metal. Copper can be extracted from sulfide ores (usually higher grade ores) by direct

    copper sulfide mineralogy was provided by Enders (2000), but a detailed mineralogical study of super-gene enrichment is lacking. The Morenci mine in Greenlee County, Arizona (Fig. 1), produces copper from supergene and hypogene deposits. Historically, the highest-grade ores at Morenci were oxide copper deposits within skarn
