Copper Ore Types: Sulfides vs. Oxides An Investor's

As with oxide ores, SX-EW tech is used to recover copper from a pregnant leach solution. Secondary sulfides, which are formed by supergene secondary enrichment, are resistant to sulfuric leaching
Details
Supergene (geology) Wikipedia

The reaction produces secondary sulfides with metal contents higher than those of the primary ore. This is particularly noted in copper ore deposits where the copper sulfide minerals chalcocite Cu 2 S, covellite CuS, digenite Cu 1.8 S, and djurleite Cu 31 S 16 are deposited by

Primary copper sulfides bioleaching vs. chloride leaching

However, comparisons are not available among technologies due to differences in scale and mineral/ore used in different studies. In this work, we have compared bioleaching and stone chloride leaching technologies (including sulfuric acid-sodium chloride ore pre-treatment) for a mainly primary copper sulfide ore.

Cobalt The primary minerals for cobalt is cobaltite. Some cobalt is also produced from weathered tropical orebodies. Columbium (see Niobium) Copper Most copper ore bodies are mined from minerals created by weathering of the primary copper ore mineral chalcopyrite. Minerals in the enriched zone include chalcocite, bornite, djurleite.

Copper Mining and Processing: Processing of Copper Ores

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different
Details
CHALCOCITE (Copper Sulfide)

Chalcocite is an important copper mineral ore. It has been mined for centuries and is one of the most profitable copper ores. The reasons for this is its high copper content (67% atomic ratio and nearly 80% by weight) and the ease at which copper can be separated from sulfur. It is not however the primary ore of copper due to its scarcity.

Copper extraction from primary copper sulfide ore from a typical porphyry copper deposit from Antofagasta, Chile, was investigated after leaching with a chloride-ferrous media at two temperatures. The study focused on whether this stone leaching system could be applied at an industrial scale. Leaching tests were conducted in columns loaded with approximately 50 kg of agglomerated ore; the

Rare-earth element Minerals and ores Britannica

Minerals and ores. The content of the individual rare-earth elements varies considerably from mineral to mineral and from deposit to deposit. The minerals and ores are generally classified as “light” or “heavy”; in the former group most of the elements present are the light-atomic-weight elements (i.e., lanthanum, cerium, praseodymium, neodymium, samarium, and europium), whereas most

Uses of Copper Supply, Demand, Production, Resources

In porphyry copper deposits, copper ore minerals are disseminated in igneous intrusions. Sediment-hosted stratabound copper deposits, in which copper is concentrated in layers in sedimentary rocks, account for about 20 percent of the world's identified copper resources. Globally, mines in these two deposit types produce about 12 million tons of

Copper Mineral Uses and Properties

Uses of Copper. Native copper was probably one of the early metals worked by ancient people. Nuggets of the metal could be found in streams in a few areas, and its properties allowed it to be easily worked without a required processing step. Today most copper is produced from sulfide ores. Copper is an excellent conductor of electricity.
