Copper is used in many different industries, including building construction, transportation, electronics and consumer goods. minerals are concentrated in specific types of geologic formations ore bodies, which are where mining takes place. these ore bodies may already contain naturallyoccurring radioactive materials norm.

Mineral deposit mineral deposit native metals only two metals, gold and platinum, are found principally in their native state, and in both cases the native metals are the primary ore minerals. silver, copper, iron, osmium, and several other metals also occur in the native state, and a few occurrences are large enoughand sufficiently richto be ore deposits.

Copper can be extracted from various types of ores, most of which belong to the sulfidic ores such as chalcopyrite, bornite, covellite, digenite and chalcocite. chalcopyrite is the most common copperbearing mineral and accounts for approximately 70 of the copper deposits in the world.1 at present,

Ore minerals. the copper deposits of the white pine mine are large stratiform deposits in the nonesuch shale of upper precambrian age. the ore is typically finely disseminated barely seen in the shale. copper concentrations average 12 copper. higher grade zones occur in open fractures from a second pulse of mineralization and the copper can ...

The ore is then ground finely before the copperbearing sulfide minerals are concentrated by a flotation process which separates the grains of ore mineral from the waste material, or gangue. depending on the type of copper bearing minerals in the ore and the treatment processes used, the concentrate typically contains between 25 and 30 copper ...

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 most common nickel mineral in these ores is pentlandite, ni,fe 9 s 8. the atomic ratio of nickel to iron in pentlandite ranges between 0.34 and 2.45. most often, though, it is about 1.15. common minerals that accompany pentlandite are pyrrhotite, fe 8 s 9, and chalcopyrite, cufes 2. cobalt and platinumgroup elements are also present ...

Vein matter is the mineral mass filling the vein it may or may not be valuable. the whole may be of value, for example, fluorspar and barite veins. or the value may be in minerals like gold, silver, copper, and other ores scattered through quartz, calcite, or other mineral forming the main part of the vein matter, the gangue.

Extraction and refining. the extraction of copper from ore is normally carried out in three major steps. the first step, mineral processing, is to liberate the copper minerals and remove waste constituentssuch as alumina, limestone, pyrite, and silicaso that the copper minerals and other nonferrous minerals of value are concentrated into a product containing between 20 and 30 percent copper.

A typical copper sulphide ore contains various levels of iron sulphide types that generally include pyrite fes2 and pyrrhotite fe1xs. often gold and silver are present which may either be associated with the sulphides or are free. the gangue particles can consist of a range of silicate minerals from quartz to talc and clays. carbonate ...
