Copper processing or pyrometallurgical processes employ high-temperature chemical reactions to extract copper from its ores and concentrates. Generally, these processes are used with copper sulfides and, in some cases, high-grade oxides. Depending on the copper mineral and the type of equipment, pyrometallurgical recovery may take as many

Copper and bronze stains appear as green or muddy-brown and result from the action of moisture on nearby or embedded bronze, copper or brass items. Metal stains must be removed with a poultice.(See section on Making & Using a Poultice) Deep-seated, rusty stains are extremely difficult to remove and the stone may be permanently stained.
Mining is the extraction of valuable minerals or other geological materials from the earth from an orebody, lode, vein, seam, or reef, which forms the mineralized package of economic interest to the miner.. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain any material that cannot ...
Processes: copper mining and production. Copper is found in natural ore deposits around the world. This page explains copper mining: the production route taken from ore-containing rock to a final product that is the highest-purity commercial metal in existence and used in a wide variety of applications essential to modern living.

Granite - The Old School RuneScape Wiki. Mining has been significant part of the Maine economy at different times in different places, thanks to its geologic composition. Granite, slate, and gem extraction have been important local industries at certain points in the state's history.
copper extraction and purification - chemguide. Extracting copper from other ores. Copper can be extracted from non-sulphide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulphuric acid to produce a very dilute copper(II) sulphate solution.

Granite (/ ˈ ɡ r æ n ɪ t /) is a coarse-grained igneous rock composed mostly of quartz, alkali feldspar, and plagioclase.It forms from magma with a high content of silica and alkali metal oxides that slowly solidifies underground.It is common in the Earth's continental crust, where it is found in bodies called plutons.These range in size from dikes only a few inches across to batholiths ...

Extraction Ores are first mechanically crushed and ground so that nearly all copper mineral particles are freed from the gangue. Flotation by the injection of air and violent agitation is carried out with the pulverized ore held in suspension in water, to which surface-active agents have been added.
1. New: To split the granite, chisels forged from wrought iron were used (doctrine = the same tools as for limestone are used, this is to say tools made from copper) 2. New: To achieve a smooth surface, the stone is split along a row of holes.Because granite splits relatively smoothly, the stones have to be burnished and polished only slightly (doctrine = the granite is sawed with copper saws)

Many methods used a century ago are still in use, but with the addition of refinements. So looking at how large and small deposits were found will change over time. (Simple example of that would be that Romans and their contemporaries didn't use geophysics, but they did find major copper deposits in Spain.) Deposits are getting harder to find.
Jan 01, 1977· Higher concentrations are obtained by extraction with E.D.T.A. : in the different types of soil in Israel (rendzinas, alluvial soils, saline hydromorphic 31 soils, etc.) 2-7.5 p.p.m. of "available" copper were found, i.e. 7-1796 of total copper; in India, in alluvial soils, vertic soils.., the corresponding contents vary from 0.45 t o 12.3 p.p ...
