For example, highgrade copper ores, which contain a high percentage of copper, are becoming harder to find and mine. There are some alternative methods to extract metals from lowgrade copper ...
Matte, crude mixture of molten sulfides formed as an intermediate product of the smelting of sulfide ores of metals, especially copper, nickel, and of being smelted directly to metal, copper ores are usually smelted to matte, preferably containing 40–45 percent copper along with iron and sulfur, which is then treated by converting in a Bessemertype converter.
Copper. Copper is mined in both open pits and underground mines, depending upon the ore grade and the nature of the ore deposit. Copper ore typically contains less that 1% copper in the form of sulphide minerals. Once the ore is delivered above the ground, it is crushed and ground to a powdery fineness and then concentrated for further processing.
Model for ferric sulfate leaching of copper ores containing a variety of sulfide minerals: Part II. Process modeling of in situ operations
The invention relates to a method for leaching an ore containing copper and cobalt in a reactor, where the copper and cobalt minerals of the ore are mainly oxidic and partially sulphidic. The copper and cobalt of the ground ore are leached at ambient pressure by means of a solution containing sulphuric acid, the pH of which has been regulated to the region of 3.
Copper ore typically contains less that 1% copper in the form of sulphide minerals. Once the ore is delivered above the ground, it is crushed and ground to a powdery fineness and then concentrated for further processing.
to limited copper reporting to the electrowinning circuit. This is a mediumbase resin, hence stripping of gold is done with dilute caustic solution containing some cyanide. Figure 1 Current and alternative flowsheets for copper and gold recovery from Au/Cu ores
In most cases copper ores contain between and 1 per cent of copper. Consequently one tonne of ore generates a maximum 6 to 10 kilograms of copper. In the case of platinum the yield is much lower: 1 tonne of ore usually contains between 3 and 6 grams of platinum. Nonetheless it is still worthwhile mining because the platinum price is high.
the continental crust contains about percent copper, or 58 parts per million. A deposit of copperbearing minerals is classed as an ore reserve if there are sufficient quantities and concentrations of minerals to be extracted at a profit. Commercial copper ore deposits today contain from to 6 percent copper, or between 100

Metals are extracted from their ores. Many copper ores contain only 2% of copper compounds. Copper is now extracted from ores containing a low percentage of copper compounds. Suggest two reasons why.
Ores that contain copper in the are typically mined in large, openpits. Copper processing facilities are usually located near mining or extraction sites. Significant waste volumes are associated with copper production. Mine wastes may contain radionuclides due to their natural presence in ores and can be a source of TENORM.
mately stable. In this context, before feeding the ore into the enrichment process, it is necessary to mix the ore to yield an initially high copper and low ore content. Therefore, when creating a mining plan in accordance with a production plan, it is necessary to plan for both ores containing a low copper content and a higher copper content.
Cobalt Ores. Sulfurous cobalt ores belong to the group of complex nickel, copper, and iron ores. The most prominent of them are magmatic coppernickel ores (in hyperbasic and basic rocks), as well as copperpyrite and scarnmagnetite ores. Pentlandite is the chief cobaltcontaining mineral in .
Matte is a molten mixture of sulphides. Of the greatest industrial importance is iron‐ copper matte which is an intermediate product in the extraction of copper from sulphide ores. In production of nickel, matte of copper‐nickel is an intermediate product. Next is copper‐ nickel matte.
Jan 21, 2015· Copper is common in the environment. You may be exposed to copper by breathing air, drinking water, eating food, and by skin contact with soil, water and other coppercontaining substances. Most copper compounds found in air, water, sediment, soil and rock are strongly attached to dust and dirt or imbedded in minerals.
Many copper ores also contain significant quantities of gold, silver, nickel, and other valuable metals, as well as large quantities of commercially useless material. Most of the copper ores mined in the United States contain only about % copper by weight. The most common sulfide ore is chalcopyrite, CuFeS 2, also known as copper pyrite or yellow copper ore.
Copper ore typically contains only about % of the actual copper mineral, the most common ore mined being chalcopyrite. The ore is attained using traditional methods of underground and open pit mining, the later accounting for 90% of the ore used in smelting.
Copper ores containing chalcopyrite can be concentrated to produce a concentrate with between 20% and 30% copperinconcentrate (usually 27–29% copper); the remainder of the concentrate is iron and sulfur in the chalcopyrite, and unwanted impurities such as silicate gangue minerals or other sulfide minerals, typically minor amounts of pyrite, sphalerite or galena. Chalcocite concentrates typically .
In this study, experiments were carried out on copper ore containing gold and silver obtained from Kisecik village of Hatay, which is in the south of Turkey. Analyses of original ore showed that the sample contained % Cu, % Co, % Zn, % Fe,, % S, g/t Au and g/t Ag.
