Wad is an old mining term for any black manganese oxide or hydroxide mineral-rich rock in the oxidized zone of various ore deposits. Typically closely associated with various iron oxides. Specific mineral varieties include pyrolusite, lithiophorite, nsutite, takanelite and vernadite. Wad can be considered to be the manganese equivalent to the iron mineraloid limonite.
copper wad 10-80% leachable at ambient temperature with dilute sulphuric acid. cuprite 50% leachable at ambient temperature with dilute sulphuric acid. chalcocite partially leachable in sulphuric acid. leachability increases with temperature and with acid stength (eg. acid cure). native copper slow leaching in sulphuric acid at

Wad, or bog manganese is a brown, soft, earthy manganese ore, variable in composition ; it looks like bog iron ore, but is often darker, and is often found with pyrolusite. Asbolite, or earthy cobalt ore, resembles wad, but contains cobalt, sometimes enough to make it a cobalt ore. Lampadite is a variety of wad containing 3% to 13% of copper ...
Copper wad predominates in this mineralised body and only minor chrysocolla is found. Mineralisation at Capella Sur is lower grade and extends deeper into the basement rocks. At Capella Este the copper mineralised zones deepen into basement rock forming a more voluminous mineralized zone with dimensions of 550 by 550 metres at depths between 45 ...

It is often found associated with and altering too malachite, but is considerable less common than this mineral. Other commonly associated minerals include chalcocite ...
Copper. Copper (Cu) is an extremely useful industrial metal that is ductile (capable of being drawn into wire), malleable (capable of being hammered and molded) and an excellent conductor of electricity (only silver is better). Copper is found in many minerals that occur in deposits large enough to mine.

The copper content is furnished, on average, by 40 vol percent atacamite, 31 vol percent copper clays with minor chysocolla and copper wad. The Lower Oxide unit is more homogeneous. Atacamite accounts for 70 vol percent of the copper ore minerals with minor amounts of copper clays and chrysocolla. Copper and chlorine concentrations and porosity ...
Wad, wadd, and/or wadt were used as early miner's terms and used for various black mineral substances. The redundant name "black wad" has been frequently attributed to Richard Kirwan in his Elements of Mineralogy (1784) but Kirwan mentioned, but did not cite, neither Josiah Wedgwood's (1783) analysis of "black wadd" nor contemporary experiments with wad by Joseph Banks, nor any earlier …

Copper is an excellent conductor of electricity. Most copper mined today is used to conduct electricity - mostly as wiring. It is also an excellent conductor of heat and is used in cooking utensils, heat sinks, and heat exchangers. Large amounts are also used to make alloys such as brass (copper and zinc) and bronze (copper, tin, and zinc).

Las fases de "copper pitch y copper wad", analizadas con el TEM bajo gran aumento (75.000 veces), muestran estructuras fibrosas y hojosas, siendo sin embargo, de carácter amorfo de acuerdo a las imágenes de difracción obtenidas con el TEM (Figura 2).
Oxidized black copper ores are known for their difficulty in dissolving their components of interest through conventional methods. This is due to its non-crystalline and amorphous structure. Among these minerals, copper pitch and copper wad are of great interest because of their considerable concentrations of copper and manganese.

At the El Salvador porphyry copper deposit in northern Chile the majority of the exotic ore comprised a mixture of copper-bearing manganese oxyhydrates termed "copper wad." X-ray diffraction, scanning electron microscopy, and electron probe microanalysis show that the copper wad is composed of copper-bearing cryptomelane [K 1-2 (Mn 3+ Mn 4+ ) 8 ...
Hosted in porphyry intruded into Triassic and Palaeozoic rocks, the economic mineralisation is differentiated by mineral assemblage into an Upper Oxide unit – with 40% by volume of atacamite, 31% copper clays and minor chrysocolla and copper wad – and the Lower unit with 70% atacamite and minor copper clays and chrysocolla.
Copper is a common element in many minerals and sometimes occurs in pure, native form. Most of the world's copper comes from the minerals chalcopyrite and chalcocite. Chrysocolla and malachite also are mined for copper. Other copper-bearing minerals include atacamite, azurite, bornite, brochantite, cuprite (copper oxide), dioptase, rosasite ...
The resources were estimated only for oxide, mixed, wad and enriched copper mineralization which can be processed by heap leaching (HL) and run of mine (ROM) dump leaching to produce copper cathode.

Supergene processes in porphyry copper deposits are important for their economic potential (Sillitoe, 2005). Meteoric fluids oxidize the upper part of the sulfidic deposit; oxidation of certain sulfide minerals, such as pyrite, produces sulphuric acid and lowers the pH, resulting in the mobilization of divalent metal cations like copper. Copper may re-precipitate more at depth, depending on ...
