Cerro Verde, an affiliate of FreeportMcMoRan Inc., seeks to triple copper concentrator production at its Cerro Verde mine requiring additional sulfide ore processing capacity. Expansion of the concentrator facilities will increase production of primary sulfide ore and will increase annual production of copper and molybdenum concentrates beginning in 2016.

The process of liberation of copper ores depends upon whether they are oxide or sulfide ores. Subsequent steps depend on the nature of the ore containing the copper. For oxide ores, a hydrometallurgical liberation process is normally undertaken, which uses the soluble nature of the ore minerals to the advantage of the metallurgical treatment plant. For sulfide ores, both .

MultiG processes allow the separation of very fine particles to occur (in the range of 5 to 50 micron) by increasing the driving force of separation in order to increase the rate at which particles separate. In general, single G process are only capable of processing particles that are greater than approximately 80 micron in diameter.

· The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron(III) oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace. These materials are loaded into the blast furnace from the top while a blast of hot air is introduced into it from beneath via small pipes .

Commercially exploited deposits of copper ores are found in many parts of the world, frequently associated with mountainbuilding processes. Deposits occur at many loions in the western cordillera of the Americas, mainly in the United States and Chile, and in areas of the North American plains like Michigan, Ontario, Quebec and Manitoba, at sites associated with the PreCambrian shield ...

Extracted ore, no matter the mineral, is typically first crushed, and then must go through a beneficiation process to remove the unwanted impurities. Beneficiation can vary significantly from one ore type to the next. In most cases, however, beneficiation is carried out through a wet process that necessitates a subsequent drying step. Mineral drying at this stage offers .

Sometimes, leaching can be performed by microbes, a process that is an attractive and profitable process for the dissolution of metals from laterite ore. Microbebased leaching is often the preference when typical mining approaches are ineffective or too expensive. Such treatments have offered access to copper, gold, lead, nickel, and zinc. Sulfuroxidizing bacteria are .

Copper extraction refers to the methods used to obtain copper from its 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.. As in all mining operations, the ore must usually be beneficiated (concentrated).
