    MANAGERIAL REVIEW Examining the copper value chain

    Mining sulfidic ores The first step in the value is mining the ore. As the copper content of the ore has only % copper, it is enriched by flotation to a copper concentrate with about 2535 % copper to avoid processing of a high amount of gangue material. So copper concentrate is the first traded product with a value. There are mining companies with their own smelting and refining ...

    Cuprite (copper I oxide)

     · Cuprite (copper I oxide) Mineral Properties and Occurence. Cuprite is a minor ore of copper, usually appearing as secondary encrustations on primary copper ores. Nice and rare cuprite crystals are a popular among collectors. It is prized as a gemstone because of its vivid red internal reflection, but its softness precludes wide use in jewelry.

    copper ore sulfidic

    Generally copper ores are classified into sulfidic and oxidic copper ores whereas oxidic ores are a naturally oxidation product of sulfidic ores. Therefore usually oxidic and sulfidic copper ores are in adjoining sites. 1 Whereas sulfidic copper ores are mainly treated by pyrometallurgical processes.

    Consequently, sulfidic copper ores have received much attention. A review of Edmiston in 1984 describes 12 chloridebased processes. All managed to progress past the "laboratory beaker" stage of evaluation. In nine of these processes, copper is recovered electrolytically. Key features of these processes are summarized in Table 1. Table 1 shows that the processes must include a copper .

    Environmental Guidelines for Nickel Smelting and Refining

    Sulfidic ores, often found in conjunction with copper bearing ores, are mined from underground. Following is a description of the processing steps used for the two types of ores. Lateritic ore processing Lateritic ores have a high percentage of free and combined moisture which must be removed. Drying removes fee moisture and chemically bound water is removed by a reduction furnace which also ...

    Complex sulfide ores containing sulfides of copper, zinc, and lead are especially common, as are complex copper, nickel, cobalt, antimony, and mercury ores. Many sulfide ores contain Pt, Au, Ag, Cd, In, Se, and Te as admixtures. Most deposits of sulfide ores are endogenous, and among those, hydrothermal deposits predominate. The ore bodies are most often veins, but they may also be sheets ...
