A mesophilic acidophiles culture was isolated from the acidic solution of the underground copper mine of Bor, Serbia. The nutrient medium was 9K at pH 1.6. 87% of the particles were <10 µm in size, with a pulp density of 8% (w/v). Bioleaching efficiencies of 89% for zinc, 83% for copper, and 68% for iron can be achieved in the examined ...

1. Introduction. As copper sulfide ore resources deplete around the world and their new deposits are increasingly difficult to be discovered, the exploitation and beneficiation of copper oxide deposits become a trend [,,,, ].The widespread and effective approach for enriching valuable minerals from their ores is of froth flotation [,,,, ].In the process of froth flotation, the mineral ...

Copper oxides are unusual in two respects. First, octahedral-site Cu(II): t 6 e 3 contains a single e hole in the 3d shell, which makes it orbitally degenerate and therefore a strong Jahn–Teller ion; consequently, Cu(II) ions normally occupy octahedral sites that are deformed to tetragonal (c/a > 1) symmetry by Jahn–Teller orbital ordering. However, in the absence of a cooperativity that ...

fide ore from volcanogenic massive sulfide deposits. The volcanogenic massive sulfide ore type is the most exploited type in Fennoscandia Shield.[16] The ore of Pyhäsalmi contains copper (Cu), zinc (Zn), iron (Fe), and sulfur (S). In general, the mineral composition of ore deposits varies in terms of changing ore minerals, their

Au-Cu mineralization at Palai-Islica occurs as disseminations in massive silicified volcanic rocks and, more abundantly, in sulphide-bearing quartz veins. The major ore minerals in the deposit are pyrite ± chalcopyrite, sphalerite and galena and there is a great variety of accessory minerals, including Au-Ag alloys and native gold.

Weathering processes and Supergene ore Deposits Sulfide ore bodies have been subjected to weathering at or near the surface of the Earth after eons of erosion removed overlying rocks. Sulfide minerals are not stable at the earth's surface and breakdown during weathering liberating metallic ions (e.g., Cu2+, Pb2+, Zn2+, Ag2+). The surface ...

Smith (2008) introduce the supergene oxide ore mineral assemblages observed for the Khanong copper deposit. Overall, there is very little previous information available on: (a) the nature of gold occurrence, and; (b) the timing of gold and copper mineralisation occurring in …

Nickel is commonly present in two principal ore types – sulfide or laterite ores. Sulfide ores are typically derived from volcanic or hydrothermal processes and usually include copper (Cu) and/or cobalt, and sometimes other precious metals such as gold or platinum and palladium (generally grouped as platinum group metals or PGMs).

There are two main types of copper ore of interest: copper oxide ores and copper sulfide ores. Both ore types can be economically mined, but they are processed in different ways. Copper sulfide ...

1.2. Chalcopyrite Ore Production The sulfide ore minerals including chalcopyrite (CuFeS 2), sphalerite (ZnS), galena (PbS) provide the major sources of the world's base metals (Cu, Zn, Pb, respectively), whereas pyrite is virtually ubiquitous as a metalliferous mineral in sulfide ore deposits (Crang and Vanghan, 1994).The first step in recovering metal from their mineral is that of finding ...

With a simple sulfide ore like chalcocite, once the sulfur has been burned off as sulfur dioxide (SO2) and the copper sulfide thus converted to copper oxide, the oxide can be reduced with charcoal, described above (Thompson 1958: 4). How the Indians happened on the roasting of sulfide ores may never be known. Obviously

Characterization of the PGM ore used in this study indicated that it was enriched in oxide minerals as a result of weathering and therefore oxidic. The maximum PGM flotation recovery achieved using sulphide co-collector schemes was 55.1% 3E (Pt, Pd, and Au). Application of the hydroxamate oxide collector improved the flotation recovery to 74.7% 3E.
