Copper extraction - Wikipedia

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.

Gold in iron oxide copper–gold deposits - ScienceDirect

Iron oxide copper–gold (IOCG) deposits contain economic or anomalous gold. • The gold is present as native gold, electrum, and gold–bismuth–antimony–tellurium alloy. • The gold distribution is controlled by gold contents in host rocks and the efficiency of precipitation mechanism.

A research project is also included in this chapter. Let the learners choose one industry and research the different aspects of mining covered in this chapter for their chosen industry. The following mining industries can be researched: gold, iron, copper, diamond, phosphate, coal, manganese, chromium or platinum group metals (PGMs).

Smelting - Wikipedia

Smelting is a process of applying heat to ore in order to extract a base metal.It is a form of extractive metallurgy.It is used to extract many metals from their ores, including silver, iron, copper, and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.

Electric Smelting Furnace of Ore

While most of the current interest in electric smelting relates to pyritic gold ores, actually more data are available on other ores, notably zinc and copper. Accordingly, we shall consider the status of electric smelting of several types of ores individually, based on the factors enumerated. Zinc Ore Smelting

how to copper oxide - Gold Refining Forum.com

Iron oxide copper-gold (IOCG) mineralization at the Imiter ...

Iron oxide copper-gold deposits (IOCG) comprise a type of mineralization formed in the geological time scale, from the Archean to Phanerozoic with most important occurrences in Australia and South America but also in Africa (Nisbet et al., 2000; Williams et al., 2005). Generally, these deposits contain massive and disseminated iron oxides ...

Ore - Wikipedia

Ore is natural rock or sediment that contains desirable minerals, typically metals, that can be extracted from it. Ore is extracted from the earth through mining and refined, often via smelting, to extract the valuable element or elements.. The grade of ore refers to the concentration of the desired material it contains. The value of the metal an ore contains must be weighed against the cost ...

Copper - Wikipedia

The cuprous oxide is converted to blister copper upon heating: 2 Cu 2 O → 4 Cu + O 2. The Sudbury matte process converted only half the sulfide to oxide and then used this oxide to remove the rest of the sulfur as oxide. It was then electrolytically refined and the anode mud exploited for the platinum and gold it contained. This step exploits ...

copper sulfate in the flux - Gold Refining Forum.com

Mar 21, 2016· hi, i dont remember who (it was from a knowledgable member so the trust is there), but longtime ago someone told me that i could use copper sulfate in a melt to upgrade the copper content on a copper/iron anode bar. but looking at copper sulfate stat is says i doent melt it "decompose" a 600deg to form anydrous copper sulfate than decompose some more to make copper oxide way …

How is Iron Refined from Ore? (with pictures)

Feb 10, 2020· The iron is periodically drained into a mold from a port at the bottom of the blast furnace, where it cools. The pig iron can then be converted into wrought iron by mixing it with silicon, or processed further to create steel. Steel is a form of iron mixed together with 0.5% - 1.5% carbon but no oxygen, silicates, or other impurities.
