“…Several much larger deposits are identified in the present study. Watterson et al 51 find this the richest of five established US mining areas surveyed for Te content although their data suggest the average Te concentration may be a lot lower than 10 g/t, too low to be of economic interest, except possibly as a by-product.…”

Previous estimates of Te and In availability for large scale use in photovoltaics have been based on considerations such as present refining capacities or on reserves calculated from the concentration of these metals in their respective Cu and Zn primary ores. The present work considers the pricing required to support direct mining of these scarce metals from ores of presently known quality. By deriving a general relationship between the market price of metals and the quality of ores from which they are mined, estimates of the market price of Te and In if mined from available ores are obtained. This allows specification of ore grades required for economic photovoltaic exploitation. Known ore deposits meeting requirements are also surveyed.

“…The stocks and associated volcanic rocks of the main part of the late Neogene magmatic arc are not alkalic, although alkalic rocks were erupted east of the volcanic front (Thompson, 1960;Noble et al, 1975;Noble and Bowman, 1976;Beckinsale et al, 1985). Although elevated Te contents are conventionally considered to be associated with alkalic rocks (e.g., Watterson et al, 1977;Bonham, 1988;Hastings, Specimens: 1, mean of 12 bulk specimens of rich enargite ore, Main Catas orebody; 2, mean composition, Cuye orebody; 3, mean composition, Main Catas orebody; 4, mean composition, Eastern Contact orebody; 5, mean composition, Antacaca orebody; 6, mean composition, Western Contact orebody; 7, mean composition of 12 samples of Pudsima Concepci6n ores cut by drill hole PC-1-86…”

Sedimentary rock-hosted disseminated precious metal mineralization at Purisima Concepcion, Yauricocha District, central Peru

Sedimentary rock-hosted disseminated gold ores lithologically and chemically similar to those of Carlin-type deposits of the western United States are present in the Yauricocha district, central Peru. The Purlsima Concepci6n deposit is located in the core of a steeply plunging anticline several hundred meters beyond large pipe-shaped Cu-Zn-Pb-Ag-Au replacement orebodies in limestone bordering a late Miocene granodiorite stock. The central part of the stock is potassium-silicate altered and contains high-salinity fluid inclusions. Mineralized impure limestone is generally decalcified and silicified and appears to have been carbonaceous. Original laminated bedding and other sedimentary structures are locally preserved. Characteristic minerals include quartz, rhodochrosite, pyrite, calcite, sericite, and barite. Pyrrhotite, arsenopyrite, plagionite (PbsSbsS17), and altaitc (PbTe) have been recognized locally. Although the chemical composition of the ores is generally similar to that of the Carlin deposit, rocks of Purlsima Concepci6n have higher Fe, Mn, Te, Ag, and T1 and lower Hg contents. Most of the Au-bearing rocks contain between 3 and 6 wt percent Fe, and Te (•4 ppm) and Mn (•4 wt %) are about two orders of magnitude higher than at Carlin. These elevated elemental concentrations are all epigenetic; there is no regional or local geologic or textural evidence for a syngenetic and/or diagenetic origin. The Ag/Au ratio of the ores is about 2.5. Gold correlates positively with Ag, As, Hg, Mo, Sb, Te, and T1 and Ag strongly with Mn. Porous, leached, but not silicified, beds tend to carry higher gold values than silicified rocks. The presence of enargite, tetrahedrite, and high S copper sulfide minerals in the replacement ores and of pyrophyllite, diaspore, alunite, anhydrite, and high-temperature (•400øC), cornpositionally complex, hypersaline fluid inclusions in altered rocks bordering enargite veins in the stock, and the intense dissolution of limestone during deposition of the polymetallic orebodies suggest that the fluids initially had low pH and high f o, andj•, values. The magmatic hydrothermal system may have been similar to that of Julcani and other enargite-tetrahedrite districts in Peru, with the differences in ore types at least in part reflecting the carbonate composition of the host rock at Yauricocha. The elemental chemistry of the Purlsima Concepci6n ores can be qualitatively explained by a process of hydrothermal differentiation in which selective precipitation of base metal and Ag sulfides and sulfosalts depleted the fluids in these components and produced a decrease in Cu/Zn, Cu/Pb, As/Sb, base metal/precious metal, and Ag/Au ratios. The moderate pH and lowfo• andj• values implied by the mineral assemblage of Purisima Concepci6n presumably reflect in part the presence of carbonaceous material. Similar deposits can be expected elsewhere in the Western Cordillera of central and northern Peru where hydrothermal fluids related to Neogene stocks encountered impure carbonaceous limestone beds of the Pari...

“…据Broadhurst等人 [28] 估计, 全球当前正开采的斑岩铜矿, 其矿石的Te品位主要介于0.1~1 g/t之间, 但一些矿床显示出更高的Te含量, 如美国Bingham矿床的铜钼金矿石中Te含量估计高达 4.8 μg/g [36] . 需要指出的是, 并不是所有的斑岩铜矿床中的Te都富集在硫化物矿石中, 如美国内华达Ely矿床, Te主要富集在铜矿体外围的硅化围岩中 [37] . PGE是地壳中含量最低的一组元素, 其地壳丰度分别为: Pt(1.5 ng/g)、Pd(1.5 ng/g)、Rh(无数据)、Ir (0.04 ng/g)、Os(0.04 ng/g)、Ru(0.56 ng/g) [18] .…”
