· Gold form in several different environments, from different processes. However, typically gold occurs as minute particles of the pure or relatively pure, silver and other elements are usually present mineral native gold mixed in with and surrounded by pyrite, quartz, various carbonates, other metal sulfides and metal arsenic sulfide minerals, etc.
characteristic crystalline form. are a mixture of minerals: they are processed to yield an industrial mineral or treated chemically to yield a single or several metals. that are generally processed for only a single metal are those of iron, aluminium, chromium, tin, mercury, manganese, tungsten, and some of . Gold
Group. was one of the first metals to be worked into implements and the first metal to be smelted from . Its excellent ductility and high conductivity assure its use in modern society.
The principal copper ore mineral is chalcopyrite CuFeS2, which is commonly smelted to yield a matte containing ~50% copper. In the presence of silica flux, iron is selectively oxidized to a slag. Figure 14 shows a PSD for the Cu–Fe–S–O system at 1 atm SO 2 as a function of temperature Rosenqvist, 1978.

· Malachite and sulphides are major deposits in Kenya, with elemental composition of found at Macalder in South Nyanza-Kenya Ogola, 1987 . According to DuBois and Walsh 1970 4–6% Cu mineral deposits have been reported at Kitere near Kisii and 3–4.55% Cu …
weighs 2.265 gram per cubic centimeter or 2 265 kilogram per cubic meter, i.e. density of is equal to 2 265 kg/m³. In Imperial or US customary measurement system, the density is equal to 141.3993 pound per cubic foot [lb/ft³], or 1.3093 ounce per cubic inch [oz/inch³] .
· 4. “While some of the lead found in an artifact may have been introduced from flux or when other metals were added to the , lead so added in Bronze Age processing would usually have the same isotopic as the lead in the .” So, all 3. 5.
Metal like , zinc and lead are minute quantities contrasted to the whole of the earth. makes up only 0.0058% of the earths crust by credence. Since these minerals are rare in a geological sense, sites for mining should have fairly elevated concentrations of the mineral.
Bornite, a - mineral, and iron sulfide Cu5FeS4. Typical occurrences are found in Mount Lyell, Tasmania Chile Peru and Butte, Mont., U.S. Bornite, one of the common minerals, forms isometric crystals but is seldom found in these forms. It alters readily upon weathering
Copper ores The main copper sulphide minerals are Cu2S, covellite CuS, bornite Cu5FeS4, tetrahedrite Cu,Fe12Sb4S13 and enargite Cu3AsS4. The largest source of copper is from porphyry ore deposits in which one or a combination of …
